Spreads and Combinations Available on CME Globex

This topic describes the spread and combination instrument types available on the CME Globex platform.

A spread or combination instrument represents the simultaneous purchase and/or sale of two or more different but related instruments (legs), depending upon spread definition.

All multilegged instruments are technically defined as 'Combinations' in CME Group reference data services, and are commonly referred to as Spreads.

This table shows available exchange-recognized spread and combination types available on CME Globex.

BF Butterfly

SecuritySubType=BF

A Butterfly is a differential spread composed of three legs having equidistant expirations—the near and deferred expirations of a product on one side of the spread, and twice the quantity of the middle expirations of a product on the other side (1:2:1).

A Butterfly has:

One Product
Three legs

Leg1 (buy leg) must be the nearest expiration
Leg2 (sell leg) must be the middle expiration compared to legs 1 and 3 for two lots
Leg3 (buy leg) must be the most deferred expiration

Quantity/side ratio of the legs is +1:-2:+1
Expiration sequencing for Butterfly:

Leg 1 month < Leg 2 month < Leg 3 month
In addition, expirations differentials must be sequential and equal, Leg 2 month – Leg 1 month = Leg 3 month – Leg 2 month
Example: SR1:BF M9–U9–Z9, the June – Sept. – Dec. butterfly, 9 – 6 = 12 – 9
There are some exceptions to this (grains, meats)

Expiration sequencing for a Broken Butterfly (aka Broken Fly) is:

Leg 1 month < Leg 2 month < Leg 3 month
Example: SR1:BF H9–M9–Z9

Expiration order is the same as the Butterfly, however the equal expiration differential rule is waived

Buying a Butterfly buys leg1, sells 2 * leg2, buys leg3
Selling a Butterfly sells leg1, buys 2 * leg2, sells leg3

Example

Instrument Symbol = SR1:BF M9–U9–Z9

Leg1 = +1 SR1M4
Leg2 = -2 SR1U4
Leg3 = +1 SR1Z4

Pricing

The Butterfly Trade Price is = Leg1 – (2 * Leg2) + Leg3

Leg Price Assignment

Leg1 and leg2 are the anchor legs and assigned fair market price
Leg3 is calculated:

Trade Price + Leg 2* Leg2 – Leg1

If leg3 price is outside the daily limits, Leg3 will be adjusted to daily limit and Leg2 is recalculated
- Leg1 = Trade Price + (2 * Leg2) – Leg3

Leg2 = (Leg1 + Leg3 – Trade Price)/2
If leg2 is now outside the daily limits, leg2 will be adjusted to the daily limit and leg1 recalculated

Pricing Example

Butterfly trades at 13.5

Leg1 has Fair Market Price of = 9812.5
Leg2 has Fair Market Price of = 9857.5
Leg3 = ((Trade Price) – leg1 + (2 * leg2))
Leg3 = 9916

Pricing Example Legs Calculated Outside of Daily Limits

Leg3 outside daily limit; leg3 reset to daily limit and leg 2 is recalculated

Butterfly trades at 13.5

Leg1 has Fair Market Price of = 9812.5
Leg2 = (Leg2 Settlement Price + Leg3 – Trade Price)/2 (calculated price of leg 2 is off tick since there are two legs. Round one leg up to the nearest on tick price and round one leg down to the nearest on tick price. Those two new prices should sum to the collective calculated price of leg 2)
Leg2 = 9859.50
Leg2 = 9860
Leg3 has a Fair Market Price of = 9901

Leg2 outside daily limit; leg2 reset to daily limit and leg1 recalculated

Butterfly trades at 13.5

Leg1 = Trade Price + (2 * Leg 2) - Leg 3
Leg1 = 13.5 + 19740 – 9875.5 = 9878
Leg2 has a Fair Market Price of = 9870
Leg3 has a Fair Market Price of = 9875.5

Leg1 outside daily limit; leg1 is reset to daily limit and all legs are recalculated starting at leg3.

This process will continue for two rounds. If an on-tick price cannot be determined for the final leg (leg 1) after two attempts, the price stands. Customers can receive a non-settled price for the recalculated leg.

Leg1 outside daily limit; leg1 reset to daily limit and leg3 recalculated.

Butterfly trades at 13.5

Leg1 = 9814
Leg2 has a Fair Market Price of = 9870
Leg3 = ((Trade Price) – leg1 + (2 * leg2))
Leg3 = 9939.5

BO Butterfly

SecuritySubType=BO

The Butterfly is an options spread involving the simultaneous purchase (sale) of a call (put), the sale (purchase) of two calls (puts), and purchase (sale) of a call (put) at different equidistant strike prices with the same expirations.

A Butterfly has:

One Product
Three legs
- Leg1 (buy leg) must be a call at the lowest strike price (herein known as strike1) for a quantity of one lot
- Leg2 (sell leg) must be a call at the middle strike price (herein known as strike2) for a quantity of two lots
- Leg3 (buy leg) must be a call at the highest strike price (herein known as strike3) for a quantity of one lot
- The strikes must satisfy this equation (see below, strikes must be equidistant):

All three legs must be the same expiration
For a call Butterfly

For a put Butterfly
- strike1 – strike2 = strike2 – strike3

Leg1 (buy leg) must be a put at the highest strike price (herein known as strike1) for a quantity of one lot
Leg2 (sell leg) must be a put at the middle strike price (herein known as strike2) for a quantity of two lots
Leg3 (buy leg) must be a put at the lowest strike price (herein known as strike3) for a quantity of one lot
The strikes must satisfy this equation (see below, strikes must be equidistant):

Quantity/side ratio of the legs is +1:-2:+1
Buying a Butterfly buys leg1, sells leg2, and buys leg3
Selling a Butterfly sells leg 1, buys leg2, and sells leg3

Example

Instrument Symbol = UD:1N: BO 0808912345

Leg1 = +1 LOU8 C6600
Leg2 = -2 LOU8 C6800
Leg3 = +1 LOU8 C7000

The differential of the legs cannot be priced less than zero. Orders placed for at a price less than zero will be rejected. This spread cannot trade at a negative price.

Pricing

The BO Butterfly Trade Price is = leg1 – (2*leg2) + leg3

Leg Price Assignment

Calculate Fair Price of the Butterfly based on fair prices of the legs.
Calculate the difference between the Butterfly trade price and the calculated fair price of the spread.
Spread Trade Price = Fair Market Price; no remainder to distribute to the legs.
Any adjustment of the outright leg prices due to remainder will be assigned according to options combination leg pricing assignment rules.

Pricing Example – Equal Distribution

Butterfly trades at 57

Leg1 has Fair Market Price of = 141
Leg2 has Fair Market Price of = 46
Leg3 has Fair Market Price of = 12
Spread Fair Market Price = 141 + 12 – (2*46) = 61
Spread Trade Price - Fair Market Price = 57 – 61 = -4
There are 4 ticks to distribute
The adjustment is applied evenly as follows:

Leg1 = 141 +1 = 142
Leg2 = 46 + 1 = 45 (Note: this leg is a two lot, so the price adjustment counts double)
Leg3 = 12 - 1 = 13

Pricing Example – Unequal Distribution

Butterfly trades at 59

Leg1 has Fair Market Price of = 141
Leg2 has Fair Market Price of = 46
Leg3 has Fair Market Price of = 12
Spread Fair Market Price = 141 + 12 – (2*46) = 61
Spread Trade Price - Fair Market Price = 59 – 61 = -2
There are 2 ticks to distribute
The adjustment is applied as follows:

Leg1 = 141 -2 = 139
Leg2 = 46
Leg3 = 12

DF Double Butterfly

SecuritySubType = DF

A Double Butterfly is composed of two different Butterfly spreads with the nearest Butterfly expiration purchased (sold) and the furthest Butterfly expiration sold (purchased). The spacing of expirations in both Butterfly spreads needs to be identical, i.e. both need to be “three month” Butterflies. This causes the actual construction of the Double Fly to look like this:

Buy (sell) one of the nearest expiration, sell (buy) three of the second nearest expiration, buy (sell) three of the third nearest expiration, and sell (buy) one of the most deferred expiration.

A Double Butterfly has:

One Product
four legs

Leg1 (buy leg) must be the nearest expiration
Leg2 (sell leg) must be the next nearest expiration
Leg3 (buy leg) must be the third nearest expiration
Leg4 (sell leg) must be the most deferred expiration

Quantity/side ratio of the legs is +1:-3:+3:-1
Expiration sequencing for Double Butterfly:

Leg1 month < Leg2 month < Leg3 month < Leg4 month
In addition, expiration differentials must be sequential and equal, i.e. if Leg1 expires in June and Leg2 expires in Sept., the next two legs must have an expiration differential of three months as well, so Leg3 must expire in Dec. and Leg4 must expire in March of the next year (see symbol below for an example of this)

Example: Instrument Symbol = SR1:DF M9U9Z9H0

Leg1 = +1 SR1M4
Leg2 = -3 SR1U4
Leg3 = +3 SR1Z4
Leg4 = -1 SR1H0
Buying of Double Butterfly buys leg1, sells three of leg2, buys three of leg3, sells leg4
Selling of Double Butterfly sells leg1, buys three of leg2, sells three of leg3, buys leg4

This spread can trade at zero and at a negative price.

Pricing

The Double Butterfly Trade Price is = Leg1 – (3 * Leg2) + (3 * Leg3) – Leg

Leg Price Assignment

Leg1, leg2 and leg3 are assigned most recent price update
Leg4 is calculated using the differential of the traded spread price:

Leg1 – (3 * Leg2) + (3 * Leg3) – Trade Price

If leg4 price is outside the daily limits, Leg4 will be adjusted to daily limit and Leg1 is recalculated

Leg1 = Trade Price + (3 * Leg2) - (3 * Leg3) +Leg4

If leg1 recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

Pricing Examples

Double Butterfly trades at 13.5

Leg1 = 9812.5
Leg2 = 9857.5
Leg3 = 9857.0
Leg4 is calculated:

9812.5 – (3 * 9857.5) + (3 * 9857.0) – 13.5
Leg4 = 9797.5

Pricing Example Legs Calculated Outside of Daily Limits

Leg4 outside daily limit; leg4 reset to daily limit and leg1 is recalculated

Double Butterfly trades at 13.5

Leg1 has a calculated price:

Leg1 = Trade Price + (3 * Leg2) - (3 * Leg3) +Leg4
Leg1 = 13.5 +29572.5 – 29571.0 + 9797.5
Leg1 = 9812.5

Leg2 = 9857.5
Leg3 = 9857.0
Leg4 = 9797.5

Calendar

SecuritySubType=SP, EQ, FX, SD, EC

A Calendar spread consists of 2 instruments with the same product with different expiration months. There are variations in Calendar spreads base on the product. Each Calendar spread variation is designated through the use of a different spread type code.

Not all CME Group futures spread markets follow the convention where Buying the Spread indicates Buying the front expiry and selling the back expiry. The following markets use the logic for calendar spreads where Buying the Spread sells the front expiry month and buys the back expiry month:

CME FX
Equity

SP Standard Calendar

The Standard Calendar Spread is a futures spread involving the simultaneous purchase (sale) of one product with a nearby expiration and a sale (purchase) of the same product at a deferred expiration. The listing convention of this spread and its corresponding symbol is to have the nearby expiration first and the deferred expiration second, creating a differential spread of nearby expiration minus the deferred expiration.

A Standard Calendar Spread has:

One Product
Two legs

Leg1 (buy leg) must be the nearest expiration
Leg2 (sell leg) must be the deferred expiration

Quantity/side ratio of the legs is +1:-1
Buying a Standard Calendar Spread buys leg1, sells leg2
Selling a Standard Calendar Spread sells leg1, buys leg2

Example

Instrument Symbol = NGZ9-NGF0

Leg1 = +1 NGZ9
Leg2 = -1 NGF0

This spread can trade at zero and at a negative price. In addition, the pricing mechanics explained below correspond to CME Globex match engine price assignment. Member firms can designate a default way to handle price assignment to these legs in Clearing. As a result, it is possible to have different leg prices assigned by Clearing that will not match the prices obtained from CME Globex. This process that allows leg price adjustment on traded calendar spreads is commonly referred to as SLEDS (Single Line Entry of Differential Spreads).

Pricing

The Standard Calendar Spread Trade Price is = Leg1 – Leg2

Leg Price Assignment

Determine the anchor leg of the Standard Calendar Spread
- The leg with the most recent price update (last price update or settlement price) is the anchor leg.
- In the event of no price updates, the leg with the nearest expiration will be determined to be the anchor leg
Calculate the non-anchor leg:

If Leg 1 is used as the anchor leg, then Leg 2 = Leg 1 price – Spread Price
If Leg 2 is used as the anchor leg, then Leg 1 = Leg 2 price + Spread Price

If the calculated price is outside the daily limits, set the leg's price to its limit and recalculate the price of the anchor leg

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

In this example leg1 has the most recent price

Leg1 is the anchor leg
Leg2 is calculated:
- Leg2 = Leg1 – Trade Price of spread

Pricing Example

Standard Calendar Spread trades at -105

Leg1 = anchor price of 2558, therefore this is automatically assigned
Leg2 = 2558 – 105 = 2453

In this example leg2 has the most recent price

Leg2 is the anchor leg
Leg1 is calculated:
- Leg1 = Leg2 + Trade Price of spread

Pricing Example

Standard Calendar Spread trades at -105

Leg2 = anchor price of 2558, therefore this is automatically assigned
Leg1 = 2558 + (-105) or Leg1 – 105 = 2453

top

EQ Calendar

This Calendar Spread is a futures spread involving the simultaneous purchase (sale) of a deferred expiration with a sale (purchase) of a nearby expiration within one product. The price of this Calendar Spread is a differential between the two expirations (deferred minus nearby).

While the contract symbol convention for this spread lists the deferred leg second, buying this spread represents purchase of the second leg and sale of the first leg. This is different from other Calendar Spreads listed on CME Globex.

This Calendar Spread has:

One Product
Two legs

Leg1 (sell leg) must be the nearest expiration
Leg2 (buy leg) must be the furthest expiration

Quantity/side ratio of the legs is -1:+1
Buying this Calendar Spread sells leg1, buys leg2
Selling this Calendar Spread buys leg1, sells leg2

Example

Instrument Symbol = ESU9-ESZ9

Leg1 = - 1 ESU9
Leg2 = +1 ESZ9

This Calendar Spread may have a smaller minimum tick than the outright futures legs or the same tick for both as the legs. This spread can trade at zero and at a negative price. In addition, the pricing mechanics explained below correspond to CME Globex match engine price assignment. Member firms can designate a default way to handle price assignment to these legs in Clearing. As a result, it is possible to have different leg prices assigned by Clearing that will not match the prices obtained from CME Globex. This process that allows leg price adjustment on traded calendar spreads is commonly referred to as SLEDS (Single Line Entry of Differential Spreads).

Pricing

This Calendar Spread Trade Price is = Leg2 – Leg1

Leg Price Assignment

Determine the anchor leg of this Calendar Spread
- The anchor leg is the prior day settlement price of Leg1
Calculate the non-anchor leg:

Leg 2 = Spread Price + Leg1 price

If the calculated price is outside the daily limits, set the Leg2 price to its limit and recalculate the price of Leg1

Leg1 = Leg2 – Spread Price

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

Pricing Examples

This Calendar Spread trades at 80.65

Leg1 has a prior day’s settlement of 2880.30
Leg2 = Trade Price + Leg1

80.65 + 2880.30

Leg2 = 2960.95

This Calendar Spread trades at 80.65

Leg2 has a lower limit price of 2967.95
Leg1 = Leg2 – spread trade price

2967.95 – 80.65

Leg2 = 2887.30

top

FX Deferred Calendar

SecuritySubType = FX

The Deferred Calendar Spread is a futures spread involving the simultaneous purchase (sale) of one product with a deferred expiration and a sale (purchase) of the same product at a nearby expiration. The listing convention of this spread and its corresponding symbol is to have the further expiration listed first and the nearby expiration listed second, creating a differential spread price of deferred expiration price minus the nearby expiration price.

A Deferred Calendar Spread has:

One Product
Two legs

Leg1 (buy leg) must be the deferred expiration
Leg2 (sell leg) must be the nearby expiration

Quantity/side ratio of the legs is +1:-1
Buying a Deferred Calendar Spread buys leg1, sells leg2
Selling a Deferred Calendar Spread sells leg1, buys leg2

Example

Instrument Symbol = GDX9-GDV9

Leg1 = +1 GDX9
Leg2 = -1 GDV9

This spread can trade at zero and at a negative price. In addition, the pricing mechanics explained below correspond to how the Globex Matching Engine assigns prices.

Pricing

The Deferred Calendar Spread Trade Price is = Leg1 – Leg2

Leg Price Assignment

Determine the anchor leg of the Deferred Calendar Spread

The anchor leg is the prior day settlement for leg2.

Calculate the non-anchor leg:

Leg 2 is used as the anchor leg, then Leg 1 = Leg 2 price + Trade Spread Price

If the calculated price is outside the daily limits, set the leg1 price to its limit and calculate the price of leg2

Leg2= Leg1 - Trade Price of the spread

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

In this example leg2 has prior day’s settlement price

Deferred Calendar Spread trades at 10

Leg2 prior day settle is 39905
Leg1 is calculated
- 39905 + 10
- Leg1 = 39915

Leg1 = Leg2 + Trade Price of the spread

top

SD Calendar

SecuritySubType = SD

This Calendar Spread is a futures spread involving the simultaneous purchase (sale) of one product with a deferred expiration and a sale (purchase) of the same product at a nearby expiration. SecuritySubType = SD is specific to FX Calendar spreads. The listing convention of this spread and its corresponding symbol is to have the further expiration listed first and the nearby expiration listed second, creating a differential spread price of deferred expiration price minus the nearby expiration price.

This Calendar has:

One Product
Two legs

Leg1 (buy leg) must be the deferred expiration
Leg2 (sell leg) must be the nearby expiration

Quantity/side ratio of the legs is +1:-1
Buying this Calendar buys leg1, sells leg2
Selling this Calendar sells leg1, buys leg2

Example

Instrument Symbol = 6BM7-6BJ7

Leg1 = +1 6BM7
Leg2 = - 1 6BJ7

This Calendar may have a smaller minimum tick than the outright futures legs or the same tick for both as the legs. This spread can trade at zero and at a negative price. In addition, the pricing mechanics explained below correspond to how the Globex Matching Engine assigns prices. It is common for member firms to designate a default way of handling price assignment to these legs in Clearing. As a result, it is common to have different leg prices assigned by Clearing that will not match the prices obtained from Globex. This process that allows leg price adjustment on traded calendar spreads is commonly referred to at CME as “SLEDS”.

Pricing

This Calendar Trade Price is = Leg1 – Leg2

Leg Price Assignment

Determine the anchor leg of the Calendar

The leg with the most recent price update is the anchor leg.

In the event of no price updates, the leg with the nearest expiration will be determined to be the anchor leg

Calculate the non-anchor leg:

If Leg 1 is used as the anchor leg, then Leg 2 = Leg 1 price – Spread Price
If Leg 2 is used as the anchor leg, then Leg 1 = Leg 2 price + Spread Price

If the calculated price is outside the daily limits, set the leg's price to its limit and recalculate the price of the anchor leg

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

In this example leg1 has the most recent price

This Calendar trades at 10

Leg1 = 14965
Leg2 is calculated

Leg1 – Trade Price of the spread
14965 - 10

Leg2 = 14955

In this example leg2 has the most recent price

This Calendar trades at 10

Leg2 = 14960
Leg1 is calculated
- 14960 + 10
- Leg1 = 14970

Leg1 = Leg2 + Trade Price

EC Calendar

SecuritySubType = EC

The EC Calendar Spread is a calendar future spread involving the simultaneous purchase (sale) of one product with a nearby expiration and a sale (purchase) of the same product at a deferred expiration. The listing convention of this spread and its corresponding symbol is to have the nearby expiration first and the deferred expiration second, creating a differential spread of the nearby expiration minus the deferred expiration.

The EC Calendar strategy type currently supports TAS,TAM and BTIC calendar spreads.

EC Calendar Spread structure:

One Product
Two legs

Leg1 (buy leg) must be the nearest expiration
Leg2 (sell leg) must be the deferred expiration

Quantity/side ratio of the legs is +1:-1
Buying an EC Calendar Spread buys leg1, sells leg2
Selling an EC Calendar Spread sells leg1, buys leg2

Example

Instrument Symbol = CLTX1-CLTZ1

Leg1 = +1 CLTX1
Leg2 = -1 CLTZ1

Pricing

The EC Calendar Spread trade price is = Leg1 - Leg2

Leg Price Assignment

Leg1 is the anchor leg and priced at zero
Leg2 is calculated:

Leg1 - Spread Trade Price

EC Calendar Spreads Leg Price Assignment

Trades executed in the EC Calendar spreads are at a to be determined price. The final leg prices are assigned by clearing.

Leg1 is always priced at zero
Leg2 is always priced at zero minus the EC Calendar Spread traded price

If the EC Calendar Spread traded price is zero, the resulting Leg2 price will be zero
If the EC Calendar Spread traded price is negative, the resulting Leg2 price will be positive
If the EC Calendar Spread traded price is positive, the resulting Leg2 price will be negative

The following examples are of the EC Calendar Spread, using the underlying TAS futures outright contract settlement prices:

Leg1 TAS underlying contract CLX1 settle price = 4961
Leg2 TAS underlying contract CLZ1 settle price = 4980

EC Calendar Spread traded price is 0

CLTX1 is priced at 0
CLTZ1 is priced at 0
Clearing assigns the following:

CLX1 assigned price = 4961
CLZ1 assigned price = 4980

EC Calendar Spread traded price is -2

CLTX1 is priced at 0
CLTZ1 is priced at 2

0- (-2) = 2

Clearing assigns the following:
- Leg2 = 4980 + 2 = 4982

CLX1 assigned price = 4961
CLZ1 assigned price = 4980- (-2) = 4982

EC Calendar Spread traded price is 3

CLTX1 is priced at 0
CLTZ1 is priced at -3

0 – 3 = -3

Clearing assigns the following:

CLX1 assigned price = 4961
CLZ1 assigned price = 4980 -3 = 4977

CF Condor

SecuritySubType=CF

A Condor is a differential futures spread composed of one product with four different expirations. Buying (selling) a Condor buys (sells) the nearest and most deferred expirations while simultaneously selling (buying) the middle two expirations.

In its purest form, a Condor’s component expirations are equidistant and consecutive. On CME Globex, this is not the case with every listed Condor. As a result, the above definition represents what a customer may find as a listed Condor instrument on CME Globex.

A Condor has:

One Product
Four legs

Leg1 (buy leg) must be the nearest expiration
Leg2 (sell leg) must be the second nearest expiration
Leg3 (sell leg) must be the third nearest expiration
Leg4 (buy leg) must be the most deferred expiration

Quantity/side ratio of the legs is +1:-1:-1:+1
Expiration sequencing for Condor:

Leg1 month < Leg2 month < Leg3 month < Leg4 month
Example: SR1:CF M9U9Z9H0

Buying a Condor buys leg1, sells leg2, sells leg3, buys leg4
Selling a Condor sells leg1, buys leg2, buys leg3, sells leg4

Example

Instrument Symbol = SR1:CF M9U9Z9H0

Leg1 = +1 SR1M4
Leg2 = -1 SR1U4
Leg3 = -1 SR1Z4
Leg4 = +1 SR1H4

This spread can trade at zero and at a negative price.

Pricing

The Condor Trade Price is = Leg1 – Leg2 – Leg3 + Leg4

Leg Price Assignment

Leg1, Leg2 and Leg3 are anchor legs and assigned prices based on one of the following rules (priority given to the lowest number rule that applies)

Last traded price
Significant bid or offer that did not trade
Settlement price

Leg4 is calculated:
- If leg1 has a calculated price outside of the daily limit, leg1 is adjusted to daily limit and leg2 price is recalculated
- If leg2 has a calculated price outside the daily limits, leg2 will be adjusted to the daily limit and leg3 recalculated

Trade Price – Leg1 + Leg2 + Leg3
If leg4 price is outside the daily limits, Leg4 will be adjusted to daily limit and Leg1 is recalculated

If leg3 has a recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

Pricing Example

Condor trades at 13.5

Leg1 most recent price update = 9812.5
Leg2 most recent price update = 9857.5
Leg3 most recent price update = 9875.5
Leg4 is calculated:

Trade Price – leg1 + leg2 + leg3
13.5 – 9812.5 = -9799 + 9857.5 + 9875.5
Leg4 = 9934

Pricing Example - Legs Calculated Outside of Daily Limits

Leg4 outside daily limit; leg4 reset to daily limit and leg1 is recalculated

Condor trades at 13.5

Leg1 is recalculated:

Leg1 = Trade Price + leg2 + leg3 – leg4
13.5 + 9857.5 + 9875.5 – 9900
Leg1 = 9846.5

Leg2 has Fair Market Price = 9857.5
Leg3 has Fair Market Price = 9875.5
Leg4 = daily limit

Leg4 = 9900

Leg1 outside daily limit; leg1 reset to daily limit and leg2 recalculated

Condor trades at 13.5

Leg1 = daily limit

Leg1 = 9814

Leg2 is recalculated:

Leg2 = leg1 – leg3 + leg4 – Trade Price
9814 – 9875.5 + 9900 – 13.5
Leg2 = 9825

Leg3 has a Fair Market Price of = 9875.5
Leg4 = daily limit

Leg4 = 9900

Leg2 outside daily limit; leg2 reset to daily limit and leg3 recalculated

Condor trades at 13.5

Leg1 = 9814
Leg2 = daily limit

Leg2 = 9870

Leg3 is recalculated:

Leg3 = leg1 – leg2 + leg4 – Trade Price
9814 – 9870 + 9900 – 13.5
Leg3 = 9830

Leg4 = 9900

CO Condor

SecuritySubType=CO

The Condor is an options spread involving the simultaneous purchase (sale) of a call (put), sale (purchase) of a second call (put), sale (purchase) of a third call (put), and purchase (sale) of a fourth call (put). All strike prices must be equidistant (i.e. the interval between the first and second strike must match the interval between the second and third strike, as well as between the third and fourth strike), and of the same expiration.

A Condor has:

One Product
Four legs

For a call Condor
- Leg1 (buy leg) must be a call at a certain strike price
- Leg2 (sell leg) must be a call at a higher strike price than leg1
- Leg3 (sell leg) must be a call at a higher strike price than leg2
- Leg4 (buy leg) must be a call at a higher strike price than leg3
For a put Condor

Leg1 (buy leg) must be a put at a certain strike price
Leg2 (sell leg) must be a put at a lower strike price than leg1
Leg3 (sell leg) must be a put at a lower strike price than leg2
Leg4 (buy leg) must be a put at a lower strike price than leg3

Example

Instrument Symbol =

Leg1 = +1
Leg2 = -1
Leg3 = -1
Leg4 = +1

Example

Instrument Symbol = UD:1V: CO 0911959621

Leg1 = +1 ESU8 C2870
Leg2 = -1 ESU8 C2875
Leg3 = -1 ESU8 C2880
Leg4 = +1 ESU8 C2885

This spread can trade to a minimum price of zero.

Pricing

The Condor Trade Price is = [Leg1+Leg4] – [Leg2+Leg3]

Leg Price Assignment

Calculate Fair Price of the Condor based on fair prices of the legs.
Calculate the difference between the Condor trade price and the calculated fair price of the spread.
Spread Trade Price = Fair Market Price; no remainder to distribute to the legs.
Any adjustment of the outright leg prices due to remainder will be assigned according to options combination leg pricing assignment rules.

Pricing Example – Equal Distribution

Condor trades at 150

Leg1 has Fair Market Price of = 2900
Leg2 has Fair Market Price of = 2550
Leg3 has Fair Market Price of = 2150
Leg4 has Fair Market Price of = 1850
Spread Fair Market Price = [2900+1850] – [2550+2150] = 50
Spread Trade Price - Fair Market Price = 150 – 50 = 100
There are 4 ticks to distribute.
The adjustment is applied evenly as follows:

Leg1 = 2900 + 25 = 2925
Leg2 = 2550 – 25 = 2525
Leg3 = 2150 – 25 = 2125
Leg4 = 1850 + 25 = 1875

Pricing Example – Unequal Distribution

Condor trades at 175

Leg1 has Fair Market Price of = 2900
Leg2 has Fair Market Price of = 2550
Leg3 has Fair Market Price of = 2150
Leg3 has Fair Market Price of = 1850
Spread Fair Market Price = [2900+1850] – [2550+2150] = 50
Spread Trade Price - Fair Market Price = 175 – 50 = 125
There are 5 ticks to distribute.
The adjustment is applied as follows:

Leg1 = 2900 + 50 = 2950
Leg2 = 2550 – 25 = 2525
Leg3 = 2150 – 25 = 2125
Leg4 = 1850 + 25 = 1875

C1 Crack One-One

SecuritySubType=C1

The Crack One-One is a futures differential spread involving the simultaneous purchase (sale) of a distilled product (i.e. Gasoline or Ultra Low Sulfur Diesel) with a corresponding sale (purchase) of the raw product from which it was produced (i.e. WTI Crude Oil). The Crack One-One is priced in terms of the raw product which necessitates a mathematical conversion of the distilled product’s price.

A Crack One-One has:

Two different products belonging to the same product group (e.g. energy)
Two legs

Leg1 (buy leg) must be the distilled product
Leg2 (sell leg) must be the raw product

Quantity/side ratio of the legs is +1:-1
Buying a Crack One-One buys leg1, sells 2
Selling a Crack One-One sells leg1, buys 2

Examples

Instrument Symbol = CL:C1 RB-CL M5

Leg1 = +1 RBM5
Leg2 = -1 CLM5

This spread can trade at zero and at a negative price.

Pricing

The Crack One:One Trade Price is = (Leg1*42/100)-Leg2 price

Leg Price Assignment

Determine the anchor leg of the Crack One-One

The leg with the most recent price update is determined to be the anchor leg
The leg1 price must always be rounded to the nearest 50 tick increment
If leg2 is used as anchor leg, leg2 must be re-calculated once leg1 price is calculated and rounded
Leg1 = [(Spread Price + Leg 2) *100/42], rounded to the nearest 50 tick increment
Leg2 = [(Leg1 * 42) / 100] – Spread Price

If neither leg as a price update then the most recent settlement price of the legs will determine the anchor leg.
If a calculated leg price is outside the daily limits, additional processing will be applied.

Pricing Examples

Example: Leg1 as anchor leg

Crack One-One trades at 2620

Leg1 has Fair Market Price of = 23120

Leg1 = 23120
Leg1 = 23100 (rounded to nearest 50 tick)

Leg2 is calculated

Leg2 = (23100*42/100)-2620
Leg2 = 9702 -2620
Leg2 = 7082

Example: Leg2 anchor Leg

Crack One-One trades at 2620

Leg2 has most recent price

Leg2 = 7112

Leg1 is calculated:

Leg1 = (2620 + 7112) * 100/42
Leg1 = 973200/42
Leg1 = 23171.4286
Leg1 = 23150 (rounded to nearest 50 tick)

Calculate Leg2:

Leg2 = (23150*42/100)-2620
Leg2 = 9723-2620
Leg2 = 7103

PK Pack

SecuritySubType=PK

The Pack is a futures spread involving the simultaneous purchase (sale) of a series four consecutive quarterly instruments (in year duration groups) within the same product. The Pack is an average net differential between the current market price of the legs and the prior day settlement price of the legs.

A Pack has:

One Product
Four legs
Total legs in the pack must be evenly divisible by 4
Expiration of all the legs must be consecutive quarterly outright futures
Quantity/side ratio of the legs is +1:+1:+1:+1
Buying a Pack buys all components
Selling a Pack sells all components

Example

Instrument Symbol = SR1:PK 01Y Z9

Leg1 = +1 SR1Z3
Leg2 = +1 SR1H4
Leg3 = +1 SR1M4
Leg4 = +1 SR1U4

This spread can trade at zero and at a negative price.

Pricing

The Pack trade price is the average price of the differentials of each leg from its prior day’s settlement price

Leg Price Assignment

Obtain trade price of Pack
Price obtained is the differential for all legs, averaged

Integer portion of the Pack trade price is applied to all legs initially
- If the Pack trades +1.25, all legs are initially assigned a price of +1 from their respective settles
- If the Pack trades at -5.75, all legs are initially assigned a price of -2 from their respective settles
Adjust most deferred legs up or down a full point until the average differential of the legs is equal to the traded price of the Pack.
The following method calculates the number of legs of the Pack that will not have any further adjustment to their prices.

If the traded Pack price has a decimal of .25, the number of legs not given an additional point adjustment equals the number of years of the pack is multiplied by 3.
If the traded Pack price has a decimal of .50, the number of legs not given an additional point adjustment equals the number of years of the pack is multiplied by 2.
If the traded Pack price has a decimal of .75, the number of legs not given an additional point adjustment equals the number of years of the pack is multiplied by 1.

As a corollary, the number of legs that need to be adjusted up or down a point can be calculated by taking the result of the above calculation and subtracting it from the total number of legs in the product.

Examples

In all pricing examples, we will be using the SR1:PK 01Y Z4 contract.
Components and settlement prices are as follows:

Leg1 = SR1M4, prior day’s settle 9873
Leg2 = SR1U4, prior day’s settle 9858.5
Leg3 = SR1Z4, prior day’s settle 9834.5
Leg4 = SR1H4, prior day’s settle 9821

Pack trades at 5

All legs are adjusted up 5 points

The decimal portion is zero, so no additional adjustments are needed
Results

Leg1 = 9873 + 5 = 9878
Leg2 = 9858.5 + 5 = 9863.5
Leg3 = 9834.5 + 5 = 9839.5
Leg4 = 9821 + 5 = 9826

Pack trades at -5.50
- All legs are adjusted by down 5 points
- The decimal portion is .50, so (1 year * 2 = 2) legs will not receive an additional adjustment, and 2 (4 total legs – 2 leg that are not changing) will need an additional adjustment
- Results

Leg1 = 9873 - 5 = 9868
Leg2 = 9858.5 - 5 = 9853.5
Leg3 = 9834.5 - 6 = 9828.5
Leg4 = 9821- 6 = 9815

Pack trades at +5.25
- All legs are adjusted by up 5 points
- The decimal portion is .25, so (1 year * 3 = 3) legs will not receive an additional adjustment, and 1 (4 total legs – 3 leg that are not changing) will need an additional adjustment
- Results

Leg1 = 9873 + 5 = 9878
Leg2 = 9858.5 + 5 = 9863.5
Leg3 = 9834.5 + 5 = 9839.5
Leg4 = 9821+ 6 = 9827

RT Reduced Tick

SecuritySubType=RT

The Reduced Tick Calendar Spread is the simultaneous purchase (sale) of one product with a nearby expiration and a sale (purchase) of the same product at a deferred expiration. The listing convention of this spread and its corresponding symbol is to have the nearby expiration first and the deferred expiration second, creating a differential spread of nearby expiration minus the deferred expiration. Spreads with SecuritySubType RT will have a smaller tick than their corresponding outright legs.

A Reduced Tick Calendar Spread has:

One Product
Two legs

Leg1 (buy leg) must be the nearest expiration
Leg2 (sell leg) must be the deferred expiration

Quantity/side ratio of the legs is +1:-1
Buying a Reduced Tick Calendar Spread buys leg1, sells leg2
Selling a Reduced Tick Calendar Spread sells leg1, buys leg2

Example

Instrument Symbol = ZNZ9-ZNH0

Leg1 = +1 ZNZ9
Leg2 = -1 ZNH0

This spread can trade at zero and at a negative price. In addition, the pricing mechanics explained below correspond to how the CME Globex match engine assigns prices. Member firms can designate a default method to handle price assignment to these legs in Clearing. As a result, it is possible to have different leg prices assigned by Clearing that will not match the prices obtained from CME Globex. This process that allows leg price adjustment on traded calendar spreads is commonly referred to as SLEDS (Single Line Entry of Differential Spreads).

Pricing

The Reduced Tick Calendar Spread Trade Price is = Leg1 – Leg2

All prices below are in a fractional pricing format.

Leg Price Assignment

Determine the anchor leg of the Reduced Tick Calendar Spread
- The leg with the most recent price update is the anchor leg.
- In the event of no recent price updates, the prior day settle of the nearby leg will be the anchor leg.
Calculate the non-anchor leg:

If Leg 1 is used as the anchor leg, then Leg 2 = Leg 1 price – Spread Price
If Leg 2 is used as the anchor leg, then Leg 1 = Leg 2 price + Spread Price

If the calculated price is outside the daily limits, set the leg's price to its limit and recalculate the price of the anchor leg

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

Pricing Examples

Leg1 is the anchor leg

Reduced Tick Calendar Spread trades at 1040

Leg1 = anchor price of 129300
Leg2 = 129300 – 1040 = 128260

Leg2 is the anchor leg

Reduced Tick Calendar Spread trades at 1040

Leg2 = anchor price of 129310

Leg1 = 129310 + 1040 = 130350

FS Strip

Spread type = FS

A Strip is the simultaneous purchase (sale) of one product in consecutive month expirations at the average of the price of the legs. A Strip may be Exchange- or User-Defined. For any single market, only an FS or SA User-Defined Spread type will be recognized.

Spread types Average Price Strip (SA) and Futures Strip (FS) are not supported in the same market. Currently, the FS Strip for 30-Day Federal Funds Futures (ZQ) and Ethanol Futures (EH) is settled to zero. As a result, the trade entry price is a net change from settlement.

A Strip has:

One Product
Minimum of two legs
Maximum of 26 legs
Quantity/side ratio of +1:+1...+1
All legs must have same tick size

Example

Instrument Symbol = ZQ:FS 03M H0

Leg1 = +1 ZQH0
Leg2 = +1 ZQJ0
Leg3 = +1 ZQK0

This spread cannot trade at zero and at a negative price.

Pricing

The Strip Trade Price is = (Leg1 + Leg2 + Leg3…LegN)/Total number of legs

Leg Price Assignment

Calculate strip settlement price by averaging all of the legs' most recent settlement prices
Subtract the result from step 1 from the Trade Price
Add the differential from step 2 to each leg's settlement price
Leg prices may not be identical

Pricing Example

Strip trades at 13490

Average leg settlement price is 13550

Leg1 last settle price is 13750
Leg2 last settle price is 13550
Leg3 last settle price is 13350

13490 (Trade price) - 13550 (Average leg settlement price) = -60

Leg1 = 13750 (last settle price) - 60 = 13690
Leg2 = 13550 (last settle price) - 60 = 13490
Leg3 = 13350 (last settle price) - 60 = 13290

SA Average Price Strip

SecuritySubType=SA

The Average Price Strip is a CME recognized future or options spread type involving the simultaneous purchase (sale) of multiple related legs priced as the average of all included legs. Customers trading this product will receive legs priced at the Average Price Strip spread traded price.

This pricing model is unique to this spread type.

Products created with related legs and consecutive expirations will receive spread type SA in their security definition message (both in the tags 55-Symbol and in tag 762-SecuritySubType). Products designated spread type SA are priced as an average.

Products created with related legs and non-consecutive expirations will receive spread type GN in their security definition message (both in the tags 55-Symbol and in tag 762-SecuritySubType). Products designated spread type GN are priced as additive.

Spread types Average Price Strip (SA) and Futures Strip (FS) are not supported in the same market.

An Average Price Strip has three different variations according to whether it is Exchange listed, a User Defined Instrument for futures, or a User Defined Spread for options:

One Product
Minimum of 2 legs
Maximum of 26 legs
For a future Average Price Strip

All legs must be buy side futures
All expirations will be consecutive
Expirations can be measured in days or months depending on the futures contained in the Average Price Strip
Instruments can be exchange listed or user defined. See examples below for symbology.

For an Option Average Price Strip

All legs must be buy side options
All legs must be calls or puts
All legs must have the same strike price
All expirations must be consecutive
Expirations can be measured in days, weeks, or months depending on the Options contained in the Average Price Strip

Quantity/side ratio of the legs is +1 for each individual leg
Buying an Average Price Strip buys each individual leg of the spread
Selling an Average Price Strip sells each individual leg of the spread

Pricing

The Average Price Strip Trade Price is = the average price of all included legs

Leg Price Assignment

The Spread Trade Price is assigned to each leg

Pricing Example – Futures Spread Equal Distribution

Average Price Strip (SA) trades at 1657

For illustration purposes, the spread in this example contains three legs
The trade price is the average of the individual legs

The trade price is applied equally to each of the legs as follows:

Leg1 = 1657
Leg2 = 1657
Leg3 = 1657

Pricing Example – Futures Spread Equal Distribution

Average Price Strip (GN) trades at 1657

For illustration purposes, the spread in this example contains three legs
The trade price is the addition of the individual legs

The trade price is applied equally to each of the legs as follows:

Leg1 = 1657
Leg2 = 1657
Leg3 = 1657

For these spreads, there is no possibility of Unequal Distribution of Prices.

SB Balanced Strip

SecuritySubType=SB

The SB Balanced Strip Spread is the simultaneous purchase or sale of futures strips at the differential price of the legs. SB is only available in futures markets in both Exchange-Defined and User-Defined spreads.

An SB Strip has

One product
Two legs
Quantity/side ratio of +1:-1
Expiration of all legs must be different and symmetric

FS, SA or AB Strips must have the same number of legs
FS, SA or AB Strips must not share any outright legs
FS, SA or AB Strips must have the same duration (3 months, 6 months, etc.)

Pricing

The Spread Trade Price is the differential of the strip legs
Leg price assignment
1. Determine anchor strip leg
  1. Leg with most recent trade, best bid/best offer, or Indicative Opening Price; else Leg1
2. Calculate the non-anchor leg:
  1. If Leg 1 is used as the anchor leg, then Leg 2 = Leg 1 price – Spread Price
  2. If Leg 2 is used as the anchor leg, then Leg 1 = Leg 2 price + Spread Price

Pricing Example

SB Balanced (SA) Strip Spread NG:SB 05M X6-X7 trades at 4

Strip Leg1 has the most recent trade at price 3229 and is designated the anchor

Strip Leg1 = 3229
Strip Leg2 = 3225 (Leg1 Price - Spread Trade Price)

Individual legs will be assigned prices according to FS Strip, SA Strip or AB Average Priced Bundle leg pricing rules.

SR Strip

SecuritySubType=SR

The Strip is an options spread involving the simultaneous purchase (sale) of a series of calls or puts at the same strike price comprised of four equidistant expirations.

A Strip has:

One Product
Four legs
- Leg1 must be a call in Exp1
- Leg2 must be a call in Exp2
- Leg3 must be a call in Exp3
- Leg4 must be a call in Exp4
- Leg1 must be a put in Exp1

Leg1 = +1 SR1Z3 C9675
Leg2 = +1 SR1H4 C9675
Leg3 = +1 SR1M4 C9675
Leg4 = +1 SR1U4 C9675

The minimum tradeable price of a Strip is the sum of the minimum prices of the legs provided it results in a tradeable tick for the combination. Orders entered below this minimum price or at an untradeable tick will be rejected. This spread cannot trade zero or negative.

Pricing

The Strip Trade Price is = Leg1 + Leg2 + Leg3 + Leg4

Leg Price Assignment

Calculate Fair Price of the Strip based on fair prices of the legs.
Calculate the difference between the Strip trade price and the calculated fair price of the spread.
Spread Trade Price = Fair Market Price; no remainder to distribute to the legs.
Any adjustment of the outright leg prices due to remainder will be assigned according to options combination leg pricing assignment rules.

Pricing Example – Equal Distribution

Strip trades at 206.5

Leg1 has Fair Market Price of = 41
Leg2 has Fair Market Price of = 48.5
Leg3 has Fair Market Price of = 54
Leg4 has Fair Market Price of = 59
Spread Fair Market Price = 202.5
Spread Trade Price - Fair Market Price = 206.5 – 202.5 = 4.0
There are 8 ticks to distribute.
The adjustment is applied evenly as follows:

Leg1 = 41 + 1 = 42
Leg2 = 48.5 + 1 = 49.5
Leg3 = 54 + 1 = 55
Leg4 = 59 + 1 = 60

Pricing Example – Unequal Distribution

WS Unbalanced Strip

SecuritySubType=WS

Unbalanced Strip is a spread between two strips in the same product (Intra-commodity), but with differing durations (to allow for spreads between Winter and Summer, etc.). An Unbalanced Strip is constructed by buying the first expiring strip and selling the later expiring strip (Buy 1 stripExp1, Sell 1 stripExp2). The durations of each strip cannot be equal. The balance of the strip will continue to expire until only one expiration month remains.

Construction: Buy StripLeg1exp1 Sell StripLeg2exp2

Security Definition Example: GL:WS X2-J3

Example: Buy the Spread

Buy 1 November 2012 5Month Strip (GL:SA 05M X2) and

Sell 1 April 2013 7Month Strip (GL:SA 07M J3)

IS Inter-Commodity Futures

SecuritySubType=IS

The Inter-Commodity is a futures spread involving the simultaneous purchase and sale of two instruments in different products with similar ticks. There can be variations in the leg pricing assignments in the Inter-Commodity futures spreads based on the components of the spread.

There are different methods for leg assignment depending on the products composing the Inter-commodity spread.

A Inter-Commodity futures spread has:

Two different products
Two legs

Leg1 is the buy leg
Leg2 is the sell leg

Quantity/side ratio of the legs is +1:-1
Buying a Inter-Commodity spread buys leg1 and sells leg2
Selling a Inter-Commodity spread sells leg1 and buys leg2

Example

Instrument Symbol= NKDU9-NIYU9

Leg1 = +1 NKDU9
Leg2 = -1 NIYU9

Pricing

The Inter-Commodity futures spread Trade Price is equal to Leg1-Leg2.

When a match occurs in an Inter-Commodity spread, the traded differential is applied to either Leg1 or Leg2 to arrive at the price of the other leg.

Nikkei Inter Commodity spread

Example

Instrument Symbol= NKDU9-NIYU9

Leg1 = +1 NKDU9
Leg2 = -1 NIYU9

Leg Price Assignment

The anchor leg price is assigned at Fair Market Price
Calculate the non-anchor leg price:

If Leg1 is used as the anchor leg, then Leg2 = (Leg1 price – Spread Price)
If Leg2 is used as the anchor leg, then Leg1 = (Leg2 price + Spread Price)

A recent significant bid or offer from either outright futures leg. To be significant, a bid must be greater than settle or the most recent traded price of the instrument, or an offer must be less than settle or the most recent traded price of the instrument.
An Indicative Opening Price can be a significant bid or offer in the prior rule.
Most recent traded outright leg in either NKD or NIY products pertaining to the spread in question, i.e. if the spread is NKDU9-NIYU9, an anchor price could be determined by the most recent trade in either NKDU9 or NIYU9.
The previous day’s settlement of the NKD outright futures
Calculate the non-anchor leg price:

If Leg1 is used as the anchor leg, then Leg2 = (Leg1 price – Spread Price)
If Leg2 is used as the anchor leg, then Leg1 = (Leg2 price + Spread Price)

Pricing Example

Example1 – Leg1 as anchor leg

Leg1 NKDU9 assigned Fair Market Price

Nikkei Inter-Commodity Spread - NKDU9-NIYU9 trades at 30

Leg1 = 21260
Leg2 = Leg1 price – Spread price

= 21260-30

=21230

Differential applied to Leg2:

Leg1 = 21260
Leg2 = 21230

Example2 – Leg1 as anchor leg

Leg1 NKDU9 assigned Fair Market Price

Nikkei Inter-Commodity Spread - NKDU9-NIYU9 trades at 30

Leg1 = 21250
Leg2 = Leg1 price – Spread price

= 21250-30

=21220

Differential applied to Leg2:

Leg1 = 21250
Leg2 = 21220

Example3 – Leg2 as anchor leg:

Leg2 NIYU9 assigned Fair Market Price

Nikkei Inter-Commodity Spread - NKDU9-NIYU9 trades at 30

Leg2 = 21245
Leg1 price = Leg2 + Spread price

= 30 + 21245

=21275

Differential applied to Leg1:

Leg1 = 21275
Leg2 = 21245

Example4 – Leg1 as anchor leg:

Leg1 NKDU9 assigned Fair Market Price

Nikkei Inter-Commodity Spread - NKDU9-NIYU9 trades at 30

Leg1 = 21200
Leg2 price = Leg1 price - Spread price

= 21200 - 30

= 21170

Differential applied to Leg2:

Leg1 = 21200
Leg2 = 21170

The Cross-Commodity Strip Spread is a futures spread involving the simultaneous purchase (sale) of one Average Priced Strip (SA) against the sale (purchase) of a second Average Priced Strip (SA) with the same expiration. Each Averaged Priced Strip must contain the same number of component parts (i.e. three consecutive futures contracts), and each Average Priced Strip must be of a different but related product (i.e. the first Average Priced Strip is WTI Crude while the second Average Priced Strip is Brent Last Day Financial Crude). After the first month of the strip from the first leg of the Cross-Commodity Strip Spread expires, the leg becomes a “balance of” spread. The balance of the Cross-Commodity Strip Spread will continue to decay until only one expiration month remains.

Important!

Average Priced Strips trade as the average price of all components, and leg assignment to those components will be the price assigned to the Average Priced Strip.

A Cross-Commodity Strip Spread has:

Two Products
Two legs
Each Leg is an Average Priced Strip with the same expiration and duration (number of component contracts)

Leg1 (buy leg) must be one product
Leg2 (sell leg) must be a related but different product from Leg1

Quantity/side ratio of the legs is +1:-1
Buying an Cross-Commodity Strip Spread buys leg1, sells leg2
Selling an Cross-Commodity Strip Spread sells leg1, buys leg2

Example

Instrument Symbol = PW:XS 02M EJL-B6L X9
- EJLX9
- EJLZ9
- B6LX9
- B6LZ9

Leg1 = +1 EJL:SA 02M X9 (2 Month Strip)
Leg2 = -1 B6L:SA 02M X9 (2 Month Strip)

This spread can trade at zero and at a negative price.

Pricing

The Cross-Commodity Strip Spread Trade Price is the differential between the two Average Priced Strips = Leg1 – Leg2

Leg Price Assignment

Determine the anchor leg of the Cross-Commodity Strip Spread
- The leg with the most recent price update of the strip (last price update or settlement price) is the anchor leg.
Calculate the non-anchor leg:

If Leg 1 is used as the anchor leg, then Leg2 = Leg1 price – Cross-Commodity Strip Spread Price
If Leg 2 is used as the anchor leg, then Leg1 = Leg2 price + Cross-Commodity Strip Spread Price

Pricing Example

In this example Leg1 has the most recent price.

Cross-Commodity Strip Spread WS:XS 02M CL-BZ G0 trades at -325

Leg1 traded at 5757
- Leg1 is the anchor, and assigned a price of 5757
- CLG0 is assigned a price of 5757
- CLH0 is assigned a price of 5757
Leg2 has its price calculated
- Leg2 = 5757 – (–325) = 5757 + 325 = 6082
- BZG0 is assigned a price of 6082
- BZH0 is assigned a price of 6082

DI Inter-Commodity

SecuritySubType=DI

The DSF Inter-Commodity Calendar is a futures spread involving the simultaneous purchase (sale) of one interest rate product with a corresponding sale (purchase) of a second interest rate product. Both products will have the same monthly expiration. Both products will also have the same underlying term (i.e., both products will be five year notional instruments).

The DSF Inter-Commodity Calendar has:

Two Products
Two legs
- This leg will have the same monthly expiration as Leg1
- This leg will have the same underlying term as Leg1

Leg1 (buy leg) will be an interest rate product
Leg2 (sell leg) will be a different interest rate product

Quantity/side ratio of the legs is +1: -1
Buying the DSF Inter-Commodity Calendar buys leg1, sells leg2
Selling the DSF Inter-Commodity Calendar sells leg1, buys leg2

Example

Instrument Symbol = ZNZ9-N1UZ9

Leg1 = +1 ZNZ9
Leg2 = -1 N1UZ9

This spread can trade at zero and at a negative price.

Pricing

The Interest Rate Inter-Commodity Spread Trade Price is = Leg1 – Leg2

All prices below are in a fractional pricing format.

Leg Price Assignment

The anchor leg will have the most recent price update; otherwise the prior day’s settlement price from Leg1 is the anchor leg
Calculate the non-anchor leg:
- Leg2 = Leg 1 price - Trade Price
- Leg 1 = Leg 2 price + Trade Price

If Leg 1 is used as the anchor leg
If Leg 2 is used as the anchor leg

If the calculated price is outside the daily limits, set the leg's price to its limit and recalculate the price of the anchor leg

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

Pricing Examples

Example: Leg1 as anchor leg

DSF Inter-Commodity Calendar trades at 50

Leg1 has the most recent trade at 130295
Leg2 is calculated:

Leg2 = Leg1 - Trade Price
130295 - 50

Leg2 = 130245

Example: Leg2 as anchor leg

DSF Treasury Inter-Commodity Calendar trades at 50

Leg2 has the most recent trade at 129290
Leg1 is calculated:

Leg1 = Leg2 + Trade Price
129290 + 50

SI Soy Crush

Spread type = SI

The Soy Crush Spread is a differential spread involving the simultaneous purchase between the raw product (Soybeans), and the yield of its two processed products (Soybean Meal, Soybean Oil). The fixed ratio per leg represents the amount of processed products that can be obtained from the given amount of raw product.

This spread type, also known as the Soybean Crush.

A Soy Crush Spread has:

Three different but related products
Three legs
All legs must be of the same expiration

Leg1 (buy leg) must be a related processed product of leg3
Leg2 (buy leg) must be a related processed product of leg3 but different from Leg1
Leg3 (sell leg) must be the raw but related product of leg1 and leg2

Quantity/side ratio of the legs is +1:+1:-1
Buying a Soy Crush Spread buys leg1, buys 2, sells leg3
Selling a Soy Crush Spread sells leg1, sells 2, buys leg3

Example

Instrument Symbol = SOM:SI K3-K3-K3

Leg1 = +1 ZMK3
Leg2 = +1 ZLK3
Leg3 = -1 ZSK3

This spread can trade at zero and at a negative price.

The Soy Crush Spread trades at a reduced tick (.25) and is priced in terms of the raw product which necessitates a mathematical conversion to convert Soybean Meal and Soybean oil into cents per bushel.

Pricing

The Soy Crush Spread Trade Price is = (Price of leg1 * .22) + (Price of leg2 * .11) – (Price of leg3)

Leg positions used in this example:

Leg1 – Soybean Meal Futures

Leg2 – Soybean Oil Futures

Leg3 – Soybean Futures

Leg Price Assignment

Anchor legs are the Fair Market Price of two of the three legs

Calculate non-anchor leg:
- If calculated price is off tick - Adjust to on tick- off tick price < half the tick round down otherwise round up.
- If calculated price outside limits; round down for high limit violation and round up for low limit violation.
- If calculated price is off tick - Adjust to on tick- off tick price < half the tick round down otherwise round up.
- If calculated price outside limits; round down for high limit violation and round up for low limit violation.
- If calculated price is off tick - Adjust to on tick- off tick price < half the tick round down otherwise round up.
- If calculated price outside limits; round down for high limit violation and round up for low limit violation.

Leg1 = (Trade Price + Leg3) – (Leg2 * .11)) / .22
Leg2 = (Trade Price + Leg3) – (Leg1 *.22)) / .11
Leg3 = (Leg1 * .22) + (Leg2 * .11) – Trade Price

Leg2 will be adjusted to the closest price that will yield an on-tick price for Leg3. Leg 2 price adjustments should be within 12 X (tick of 1) in the normal case
Recalculate the Leg3

This spread can trade at a negative price.

IP Inter-Commodity

SecuritySubType = IP

The Inter-Commodity Spread (ICS) calendar spread for futures (commonly known as a “box spread") allows customers to trade Inter-commodity spreads as a single instrument, eliminating leg execution risk. The Inter-Commodity Spread is the net differential between the two ICS spreads.

An Inter-Commodity Spread has:

Two Products
Four legs

Leg1 (buy leg) is first leg of the first inter commodity calendar spread of near expiration
Leg2 (sell leg) is second leg of first the inter commodity calendar spread with the same expiration as leg1
Leg3 (sell leg) is first leg of the second inter commodity calendar spread of deferred expiration
Leg4 (buy leg) is second leg of second inter commodity calendar spread with the same expiration as leg3

Quantity/side ratio of the legs is +1:-1:-1:+1
Buying a Inter-Commodity Spread buys leg1 , sells leg2, sells leg3, buys leg4
Selling a Inter-Commodity Spread sells leg1, buys leg2, buys leg3, sells leg4

Example

Instrument Symbol = NG:HH K1-F2

Leg1 = +1 NGK1
Leg2 = -1 HHK1
Leg3 = -1 NGF2
Leg4 = +1 HHF2

This spread can trade at zero and at a negative price. The spread trade tick is smaller than outright legs.

Pricing

The Inter-Commodity Spread Trade Price is the net differential between the two inter commodity calendar spreads = Leg1 – Leg2 – Leg3 + Leg4

Leg Price Assignment

Leg1, Leg2 and Leg3 are anchor legs and assigned the most recent update price.
Leg4 is calculated:
- Spread Trade Price – Leg1 + Leg2 + Leg3
If leg4 price is outside the daily limits, Leg4 will be adjusted to daily limit and Leg1 is recalculated

Pricing Example

Inter-Commodity Spread trades at 1

Leg1 = most recent price update 6889
Leg2 = most recent price update 7092
Leg3 = most recent price update 6834

Reduced Tick Inter-Commodity Spread

SecuritySubType = RI

The Reduced Tick Inter Commodity is a futures spread involving the simultaneous purchase (sale) of two products with a corresponding sale (purchase) of a second related product. Spreads with SecuritySubType RI will have a smaller tick than their corresponding outright legs.

A Reduced Tick Inter Commodity has:

Two different products
Two legs

Leg1 is the buy leg
Leg2 is the sell leg

Quantity/side ratio of the legs is +1:-1
Buying a Reduced Tick Inter Commodity buys leg1, sells leg2
Selling a Reduced Tick Inter Commodity sells leg1, buys leg2

Example

Instrument Symbol = HPZ9-HHZ9

Leg1 = +1 HPZ9
Leg2 = -1 HHZ9

This spread can trade at zero and at a negative price. In addition, the pricing mechanics explained below correspond to how CME Globex assigns prices. Member firms commonly designate a default way of handling price assignment to these legs in Clearing. As a result, it is not unusual to have different leg prices assigned by Clearing that will not match the prices obtained from CME Globex. This process allowing leg price adjustment on traded calendar spreads is referred to as “SLEDS” (Single Line Entry Differential).

Pricing

The Reduced Tick Inter Commodity Trade Price is = Leg1 – Leg2

Leg Price Assignment

Determine the anchor leg of the Reduced Tick Inter Commodity

The leg with the most recent price update is the anchor leg.
In the event of no recent price updates, the prior day settle of the nearby leg will be the anchor leg.

Calculate the non-anchor leg:

If Leg 1 is used as the anchor leg, then Leg 2 = Leg 1 price – Spread Price
If Leg 2 is used as the anchor leg, then Leg 1 = Leg 2 price + Spread Price
If the calculated price is outside the daily limits, set the leg's price to its limit and recalculate the price of the anchor leg

If the recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.

Pricing Examples

Leg1 is the anchor leg

Reduced Tick Inter Commodity trades at 3.00

Leg1 = anchor price of 2656
Leg2 = 2656 – 3.00 = 2653

Leg2 is the anchor leg

Reduced Tick Inter Commodity trades at 3.0

Leg2= anchor price of 2653
Leg1= 2653 +3.00 = 2656

Security Definition Example: ZQF8G8-SR1Z3

Pricing

The Inter-Commodity Reduced Tick Ratio Spread Trade Price is the average net differential between the current market price of the two legs of one commodity and one leg of another commodity.

Spread Trade Price = AvgPx(2 sets of Com1) – Com2

If necessary, CME Globex will adjust Com1 leg prices to equal the spread price.

Leg Price Assignments

Leg 3 (Com2) is the anchor and assigned the most recent available price from the outright market; trade, best bid/best offer, or Indicative Opening Price.
Legs 1 and 2 (Com1) are assigned prices in line with the outright markets but adjusted if necessary to equal the Spread Trade Price.

Example of trade with leg price adjustment

This example illustrates the leg price assignments after adjustment.

Spread ZQF8G8-SR1Z3 trades at 0.1425

ZQF8 Early Expiry = 98.9750
ZQG8 Later Expiry = 98.9050
SR1Z3 Qtry Expiry = 98.8000

(98.9750+98.9050) / 2 = 98.9425 - 98.8000 = 0.1400

Most Recent Market Prices: (98.9750 + 98.9100) / 2 = 98.9425 - (988.000/10) = 0.1425

Adjusted Leg Prices Assigned:

ZQF8 Early Expiry = 98.9750
ZQG8 Later Expiry = 98.9100

(98.9750 + 98.9100) / 2 = 98.9425 - 98.8000 = 0.1425

GT Guts

SecuritySubType=GT

The Guts is an options combination involving the simultaneous purchase (sale) of call and a put within the same expiration. Unlike a Straddle and Strangle, a Guts combination has the strike price of the put higher than the strike price of the call.

A Guts combination has:

One Product
Two legs

Both legs must be the same expiration
Leg1 (buy leg) must be a call
Leg2 (buy leg) must be a put at a higher strike price than Leg1

Quantity/side ratio of the legs is +1:+1
Buying a Guts buys leg1, buys leg2
Selling a Guts sells leg1, sells leg2

Example

Instrument Symbol = UD:1N: GT 1016922333

Leg1 = +1 LOF9 C6900
Leg2 = +1 LOF9 P7350

The minimum price of the spread is the sum of the minimum ticks of the legs. The resulting tick must be a tradeable tick or the price will be rejected.

Pricing

The Guts Trade Price is = Leg1 + Leg2

Leg Price Assignment

Calculate Fair Price of the Guts based on fair prices of the legs.
Calculate the difference between the Guts trade price and the calculated fair price of the spread.
Spread Trade Price = Fair Market Price; no remainder to distribute to the legs.
Any adjustment of the outright leg prices due to remainder will be assigned according to options combination leg pricing assignment rules.

Pricing Example – Equal Distribution

Guts trades at 883

Leg1 has Fair Market Price of = 450
Leg2 has Fair Market Price of = 423
Spread Fair Market Price = 873

CV Covered

SecuritySubType=CV

The CV Covered is the simultaneous purchase or sale of outright options or options spreads or combination with one or more outright futures; for example, buying call options and selling futures or selling put options and selling futures. The creator of the UDS is responsible for defining the direction, delta, price, and expiration of the futures leg(s). Covereds pricing and leg assignments follow the rules of the options leg; i.e., an outright options covered with a future is priced following the rules of the option leg and a VT Vertical covered with a future is priced following the rules of the VT Vertical. The CV Covered is identified with tag 762-SecuritySubType=CV:XX, where XX is either "FO" for an outright option or the options spread type (e.g., "GN", "VT"). CV Covered is available as an options-futures User-Defined Spread only.

A CV Covered has:

Many products
At least one and up to 25 outright futures legs, with defined directions, deltas, prices and terms
At least one options outright or options spread
Any quantity ratio, so long as the ratio has the least common denominator possible
Any side ratio, as long as the first option outright or options spread leg is a buy

Pricing

The Spread Trade Price is the price or differential of the outright options or options spread legs
- A CV Covered SA Strip follows the SA pricing rules
- A CV Covered GD Strip Spread follows the GD pricing rules

Leg price assignment
1. If options leg(s) are a spread or combination, the Spread Trade Price is calculated following the defined spread rules
  1. If options leg is an outright, the Spread Trade Price is assigned to the options leg
2. Multiply the Delta times the total number of traded options
3. Assign the futures quantity at the Futures Leg Price

Pricing Example

CV Covered trades 100 lots at 25

Leg1 is a 1 lot buy options outright
Leg2 is a 1 lot sell futures outright, Delta 47 and price 200,000

Outright options Leg1 is assigned Spread Trade Price of 25
1. Futures outright Leg2 sells 47 lots (Delta * traded options quantity) at defined price of 200,000.

Both products must be of different NYMEX Energy Product Groups of unequal ticks

Leg1 (buy leg) must be an outright option with Globex Symbol beginning ON (ex. ONX8 C3150)
Leg2 (sell leg) must be an outright option with Globex Symbol beginning LNE (ex. LNEX8 C3150)
There are no requirements for option type, strike price, or expiration between the two legs
If both legs are calls or puts, the resulting instrument is a Spread
If one leg is a call and one leg is a put, the resulting instrument is a Combination

Quantity/side ratio of the legs is +1:-1
Buying a Reduced Tick Options Spread or Combination buys leg1 and sells leg2
Selling a Reduced Tick Options Spread or Combination sells leg1 and buys leg2

Example

Instrument Symbol = UD:1T: EO 1026911365

Leg1 = +1 ONX8 C3150
Leg2 = -1 LNEX8 C3150

The differential of the legs must be a tradeable tick for the new combined instrument. Orders submitted with an untradeable tick will be rejected. This spread can trade to a price of zero. This spread can also trade at a negative price.

Pricing

The EO Reduced Tick trade price is = Leg1 – Leg2

Leg Price Assignment

Calculate Fair Price of the Reduced Tick Options Spread or Combination based on fair prices of the legs.

GN Generic

SecuritySubType=GN

If the spread or combination requested by the user is not identified as one of the CME Globex recognized spread types, but has a valid construction, the instrument will be created exactly as the user requested and designated in market data as 'GN' (generic).

Under the generic designation, the user can create options spread instruments composed of multiple spread types. For example, a unique options spread instrument can be created by combining the configurations of a Vertical options spread and Xmas tree options spread into a unique Generic instrument.

Generic spreads can contain up to 26 outrights. This count is irrespective of leg ratio. For example, when the user submits a proposed user defined spread to CME Globex containing an options butterfly (buy1, sell2, buy1) as a leg, CME Globex will count that instrument as 3 (buy/sell/buy) instruments against the 26 instrument limit.

For additional information, see User-Defined Spread (UDS).

CME FX Link (XF, YF)

CME FX Link is traded on CME Globex as the differential between CME FX Futures and OTC Spot FX, resulting in the simultaneous execution of FX Futures cleared by CME Group, and OTC Spot FX transactions subject to bilateral OTC relationships. The CME FX Link spreads consist of OTC FX Spot vs. each of the front three quarterly CME FX Futures. Three consecutive CME FX Link months are listed for eligible currency pairs. A new spread will be added two weeks prior to the last trade date of an expiring CME FX Future. The OTC FX Spot leg is only tradeable as part of the CME FX Link spread.

The spreads are traded as a differential between FX Futures and OTC spot, with both legs expressed in OTC quote convention. Therefore, the spread construction is either non-inverted or inverted, depending on whether the quoting convention of the related futures leg is inverted or non-inverted with respect to the typical OTC convention for that currency pair.

With a non-inverted CME FX Link Spread (XF):

- The CME FX Future follows the same convention as the OTC market.
- The buyer of the spread buys CME FX futures and sells OTC spot. The seller sells CME futures and buys OTC spot.

With an inverted CME FX Link Spread (YF):

- The CME FX Future is inverted from the standard OTC convention.
- The buyer of the spread sells CME FX futures and sells OTC spot. The seller buys CME futures and buys OTC spot.

Non-Inverted CME FX Link Spread (XF)

Construction: Buy1FXFutureExp1 Sell1FXOTCSpot

Security Definition Example: 6E:XF:EURUSD:M8

Example: Buy the Spread

Buy 1 March 2018 CME Euro FX Future and

Sell 1 Euro / US Dollar Spot

Example: Sell the Spread

Sell 1 March 2018 CME Euro FX Future and

Security Definition Example: 6J:YF:USDJPY:M8

Example: Buy the Spread

Sell 1 March 2018 Japanese Yen Future and

Sell 1 US Dollar / Japanese Yen Spot

Example: Sell the Spread

Buy 1 March 2018 Japanese Yen Future and

Buy 1 US Dollar / Japanese Yen Spot

Selling an inverted FX futures contract is the same as buying the contract in OTC terms.

Pricing

This section provides an overview of FX Link Pricing. For more detailed pricing information, consult the FX Link quotation and pricing guide. The full economic terms of the spot instrument will be available on CME STP.

Pricing Overview

The formula for spot rate for non-inverted and inverted spreads is outlined below. The FX Link spot leg is rounded based on the Security Definition minimum tick precision (tag 969-MinPriceIncrement), after the calculations below are performed. The trade date for FX Link is the market data trade date, not the clearing trade date. Tag 527-SecondaryExecID allows linking the spread summary fill notice with the leg fill notices to determine price information.

Pricing Formula

Non-Inverted (XF)
- Spot Price = Future Price – Spread Price
Inverted (YF)
- Spot Price = (1/ Futures Price) – Spread Price

Notional Calculations

Non-Inverted (XF)
- Base Notional = Contract Size * Contract Quantity
- Quote Notional = Base Notional * Spot Price
Inverted (YF)
- Base Notional = Quote Notional / Spot Price
- Quote Notional = Contract Size * Contract Quantity

Value Date

USD/CAD = T+1 business days, all other currency pairs are T+2 business days
Value date must be a valid day in both currencies’ calendars.

AE Fixed Price Ratio Inter-Commodity

SecuritySubType=AE

The AE spread is the simultaneous purchase(sale) of two contracts of different leg quantity ratios where the spread will trade at a fixed price ratio of 1:1.

Construction

The Fixed Price Ratio Inter-Commodity futures spread is a a Fixed Price Ratio spread involving the simultaneous purchase (sale) of two different products with either the same or different expirations of different pre-determined leg ratios (e.g. 8:1).

A Fixed Price Ratio Inter-Commodity futures spread has:

Two products
Two legs
- Leg1 is the buy leg and must be the same expiration or different expiration as leg2
- Leg2 is the sell leg and must be the same expiration or different expiration as leg1
Quantity/side ratios are predetermined and detailed in the outright leg quantities
Buying the Fixed Price Ratio Inter-Commodity futures spread buys leg1 and sells leg2
Selling the Fixed Price Ratio Inter-Commodity futures spread sells leg1 and buys leg2

Example

Instrument Symbol = NGM2-NNN2

Leg1 = +1 NGM2
Leg2 = -1 NNN2

Pricing of the AE is at a Fixed Price Ratio and does not consider the outright leg quantity ratios. The spread can trade at a negative or zero. The spread can also trade at a reduced tick.

Pricing

The Fixed Price Ratio Inter-Commodity Trade Price = Leg1 - Leg2

Leg Price Assignment:

Leg1 = is the anchor and assigned the most recent market price
Leg2 = is calculated
- Leg1 is used as the anchor leg, then leg2 = leg1 price – Spread Price
- If leg2 price is calculated outside the daily limits, leg2 will be adjusted to daily limit and leg1 is calculated.

The same leg price will be applied to all legs on the side with a ratio, e.g., for NG-NN at 8:1, all 8 NG legs will be priced at the same price.

If the leg1 calculated price is outside the daily limit, the price will stand. Customers can receive a non-settled price for the recalculated leg1.

Leg pricing examples:

A quantity side ratio of +8:-1 will be used in the below example.

The Fixed Price Ratio Inter-Commodity trades at 0.00025

Leg1 = 2.574
Leg2 is calculated:
- Leg1 - Spread Trade Price
- 2.574 - 0.00025
Leg2 = 2.57375

Resulting legs:

Leg1 Buy 8 lots of NGM2 at 2.574
Leg2 Sell 1 lot of NNN2 at 2.57375

Pricing Example Leg2 Calculated Outside of Daily Limits

The Fixed Price Ratio Inter-Commodity trades at 0.00025

Assuming leg2 daily low limit is 2.6

- Leg1 = 2.574
- Leg2 is calculated:
  - Leg1 - Spread Trade Price
  - 2.574 - 0.00025
- Leg2 = 2.57375
- Since leg2 is less than low limit, reset leg2 to daily low limit 2.6
- Leg1 is calculated
  - Leg2 + Spread Trade Price
  - 2.6 + 0.00025 = 2.60025

Leg1 Buy 8 lots of NGM2 at 2.60025

Leg2 Sell 1 lot of NNN2 at 2.6

RV Curve Ratio

SecuritySubType=RV

The Curve Ratio (RV) spread trades at a yield differential. The yield books will be inverted as in a typical yield market and the Curve Ratio (RV) spread quoted prices will be in basis points, represented in decimal notation (-43.750) of the yield as quoted in percentages: -.43750%. Although the spread is traded at a yield differential and quoted prices in decimal notation, the outright legs are quoted in conventional prices; this will require a price-to-yield and yield-to-price conversion for leg price assignments.

Inverted Yield Book Example

Examples of an inverted yield book in a typical yield market are shown below.

Example: Inverted RV Curve Ratio Yield Book

In a typical yield market, the bid is higher than the ask.

Level	UB10:30	Bid	Ask	UB10:30
Inverted Book in a Typical Yield Market
Level	Price Type	Price	Price	Price Type	Level
1	Yield	-43.750	-43.751	Yield	1

Leg Quantity Ratios

Curve Ratio (RV) spreads will support quantity ratios to keep approximate DV01 neutrality. The Curve Ratio (RV) spread leg ratios are static at the instrument level and dynamic at the product level based on spread construction. The ratios can be different for different spread instruments. The quantity ratio of legs is defined in the repeating group of the Curve Ratio (RV) spread MDP3 Security Definition (tag 35-MsgType=d) message in tags 623-LegRatioQty and tag 624-Side for the leg ratio.

Quantity ratios maybe re-assessed when a new underlying (leg) is listed due to a new auction.
If a new ratio is required, an additional spread will be listed.
Curve Ratio (RV) spread quantity ratios are integers in all cases, e.g. 10:7, 5:2.
Minimum order quantity is 1.
- The quantity must be multiplied by the leg quantity ratios of the the spread (e.g. 2:10; quantity of 5 would be 10:50.).

Spread Construction

The Curve Ratio (RV) spread has:

2 products
2 legs
- Maturity 1 shall be the shorter tenor
- Maturity 2 shall be the longer tenor
Quantity/side ratio of +n:-n

Quantity Side Ratios

Quantity/side ratio of +n:-n - Ratios are static and predetermined based on spread construction.

Pricing Examples

The Curve Ratio (RV) spread is priced as the yield differential of two US Treasury Active tenors.

The RV Spread = Leg1 - Leg2

Price to Yield and Yield to Price Conversion

The spread is traded at a +- yield differential with inverted prices (bid higher than offer). The outright legs will trade in prices requiring price to yield and yield to price conversions.

Example: Curve Ratio (RV) Spread Trade and Leg Price Assignments

RV Spread UB10:30 trades 5 at -43.750 (the decimal notation of the yield as quoted in percentages: -.43750%)

Leg1 = +1 UST 10YR Bond
Leg2 = -1 UST 30YR Bond

Leg Price Assignment

Leg2 is the anchor and assigned the most recent traded price of 114.375; therefore, this is automatically assigned.
Leg1 is calculated requiring a price to yield and yield to price conversion.
- Example: calculations of yield to price and price to yield.
  - Leg1 = Spread Trade Price + PtY(Leg2 Price)
    - Trade Price of -43.750 conversion to percent for price conversion
      - -.43750% + PtY(114.375)
      - -.43750% + 1.7530838%
    - Convert Leg1 back to price:
      - Leg1 in calculated yield terms (YtP) = 1.3155838%
      - Leg1 yield to price (PtY) = 103.9695740

TB Gasoil Crack

SecuritySubType=TB

The Gasoil Crack spread is the differential spread involving the simultaneous purchase (sale) of a distilled product (e.g., Low Sulphur Gasoil) with a corresponding sale (purchase) of the raw product from which it was produced (e.g., Crude Oil). The Gasoil Crack spread will trade at a reduced tick (1) and is priced in terms of the raw product which necessitates a mathematical conversion of the distilled product's price.

The Gasoil Crack Spread has:

2 different products belonging to the same product group (e.g. energy)
2 legs
Both legs must be of the same expirations
- Leg1 (buy leg) must be the distilled product
- Leg2 (sell leg) must be the raw product
Quantity/side ratios of the legs is +4:-3
Buying a Gasoil Crack spread buys Leg1, sells Leg2
Selling a Gasoil Crack spread sells Leg1, buys Leg2

Example

Instrument Symbol = 7FV2-BZV2

Leg1 = +4 7FV2
Leg2 = -3 BZV2

Pricing of the Gasoil Crack spread is at a fixed price ratio and does not consider the outright leg quantity ratios. The spread can trade at a negative or zero price. The spread also trades at a reduced tick.

Spread Pricing

The Gasoil Crack spread Trade Price is = (Leg1 / 7.45) – Leg2 * 1

The Gasoil Crack spread is priced in terms of the raw product (e.g., Crude Oil) which necessitates a mathematical conversion of the distilled product’s (e.g., Low Sulphur Gasoil) price:

For Gasoil: 1 metric ton = 7.45 barrels

Leg Price Assignment Example

Leg2 = the anchor leg is calculated starting with the Leg2 fair market price
- Leg2 + Trade Price
  - Round to nearest 20-point increment
- Rounded (Leg2 + Trade Price) – Trade Price = Finalized rounded Leg2 price

Leg1 = calculated using a mathematical conversion and rounded to the nearest 1 cent

Leg1 = Rounded (Leg2 + Trade Price) * 7.45

The same leg price will be applied to all legs on each side with a ratio, e.g., for 7F-BZ at 4:3, all 4 7F legs will be priced at the same price and all 3 BZ legs will be priced at the same price.

Leg Pricing Example

A quantity side ratio of +4:-3 is used in the example below.

The Gasoil Crack spread trades at 1121

Leg2 has Fair Market Price of = 7778
- 7778 + 1121 = 8899
  - Rounded to nearest 20-point increment = 8900
- 8900 – 1121 = 7779

Leg1 is calculated using a mathematical conversion and rounded to the nearest 1 cent
- 8900 * 7.45 = 66305

Resulting legs:
- Leg1 = Buy 4 lots of 7FV2 at 66305
- Leg2 = Sell 3 lot of BZV2 at 7779

TG HOGO Inter-Commodity Ratio Futures

SecuritySubType=TG

The HOGO spread is the differential spread involving the simultaneous purchase (sale) a energy product (i.e., Heating Oil) with a corresponding sale (purchase) of a related energy product (i.e., Gas Oil).

A HOGO spread has:

Two different products belonging to the same product group (e.g., energy)
Two legs
Both legs must be of the same expirations
- Leg1 is the buy leg
- Leg2 is the sell leg
Quantity/side ratios of the legs is +3:-4
Buying the HOGO spread buys leg1 and sells leg2
Selling the HOGO spread sells leg1 and buys leg2

Example

Instrument Symbol = HOZ3-7FZ3

Leg1 = +3 HOZ3
Leg2 = -4 7FZ3

Important

Pricing of the HOGO spread is at a fixed price ratio and does not consider the outright leg quantity ratios. The spread can trade at a negative or zero.

The HOGO spread trade tick (1), with leg2 (Gas Oil) will trade at a smaller tick (1) than outright trading tick (25).

Pricing

The HOGO spread Trade Price is = Leg1 * 1 - Leg 2 * 1/3.129

Conversion Factor

The HOGO Spread is priced in terms of the gallons which necessitates a mathematical conversion of the price from metric tons to gallons.

Conversion factor 1 metric ton = 312.9 gallons
Conversion factor used in spread trade price = 3.129 gallons

Leg Price Assignment:

Leg1 = is the anchor and assigned Fair Market Price
- Calculate Leg1 - Trade Price
  - Round to nearest 1000 - point increment
- Calculate Leg1 final price
  - Rounded (Leg1 - Trade Price) + Trade Price
Leg2 = is calculated and rounded to the nearest 1 cent
- Convert from metric tons to gallons
  - Leg2 = Rounded (Leg1 - Trade Price) * 3.129

The same leg price will be applied to all legs on the side with a ratio, e.g., for HO-7F at 3:4, all 3 HO legs will be priced at the same price; and all 4 7F legs will be priced at the same price.

Leg Pricing Examples:

A quantity side ratio of +3:-4 will be used in the below example.

The HOGO spread trades at 2583

Leg1 has Fair Market Price of = 25210
- 25210 - 2583 = 22627
  - Rounded to nearest 1000 - point increment = 23000
- Leg1 = 23000 + 2583 = 25583
Leg2 is calculated rounded to the nearest 1 cent
- 23000 * 3.129 = 71967
Resulting legs:
- Leg1 Buy 3 lots of HOZ3 at 25583
- Leg2 Sell 4 lot of 7FZ3 at 71967

To convert leg2 to gallons use leg2/3.129

RB Butterfly

SecuritySubType=RB

The RB Butterfly is a 3-leg spread at a fixed ratio.

The RB Butterfly spreads are constructed using three separate US Active tenors.

3 Products
3 Legs
- Leg1 - Must be shortest tenor
- Leg2 - Must be the middle tenor compared to legs 1 and 3
- Leg3 - Must be the longer tenor
Quantity/side ratio of X:-Y:+Z
Buying a RB Butterfly buys Leg1(X), sells Leg2(Y), buys Leg3(Z)
Selling a RB Butterfly sells Leg1(X), buys Leg2(Y), sells Leg3(Z)

Quantity Side Ratios

Quantity/side ratio of +X:-Y:+Z Ratios are static and predetermined based on spread construction.

The RB Butterfly spreads are priced as the yield differential in basis points of three US Treasury Active Active tenors. The minimum price increment is 1/10th of one basis point.

The RB Butterfly spreads = Leg1 – (2 * Leg2) + Leg3

Price to Yield and Yield to Price Conversion

RB Butterfly spreads must be traded as a +- yield differential with a +1:-2:+1 leg price ratio (in yield). US Treasury Actives legs are traded in price, requiring price to yield and yield to price conversions.

Example: Leg Price Assignment

Leg2 and Leg3 are the anchor and assigned the most recent traded price; therefore, this is automatically assigned.
Leg1 is calculated requiring a price to yield and yield to price conversion.
- Spread price (in Yield) + 2 * PtY(Leg2 Price) - PtY(Leg3 Price)
- Trade price in basis points converted to percent for price conversion
- Trade price converted to decimal for yield to price conversion
- Convert calculated Leg1 yield into price
- Final leg1 price rounded to the same decimal precision of Leg1

RB Butterfly 3Y/5Y/7Y 2:8:5 trades 10 at 300 (the basis point notation of the yield as quoted in percentages: 3%). A ratio of 2:8:5 is being used as the leg price example.

Contract details:

Contract Type	Long Name	Ratio
Spread	3Y/5Y/7Y 2:8:5	2:8:5
Leg1	3 YEAR	2
Leg2	5 YEAR	8
Leg3	7 YEAR	5

Leg2 = 99.0078125
Leg3 = 99.453125
Leg1 is calculated requiring a price to yield and yield to price conversion.
- Example: Leg1 calculations:
  - Leg1 = Spread Trade Price + 2 * PtY(Leg2 Price) - PtY(Leg3 Price)
    - Trade Price of 300 converted to 3% percent for price conversion
      - 3% + 2 * PtY(99.0078125) - PtY(99.453125)
      - 3% + 2 * (3.4187995200941588)-(3.3284821616988167)
    - Trade Price of 3% converted to decimal for yield to price conversion
      - 3.00 + 6.837599040188-3.3284821616988167
      - = 6.509116878489
    - Convert the calculated leg1 PtY back to YtP:
      - Leg1 = YtP(91.3209739126597500) (rounded to 91.32097391)

Example: Leg Quantity and Price Assignment

Execution Report Type	Quantity and Price
Spread Fill	10@300 (trade price)
Leg1 Fill	20@91.32097391 (calculated price)
Leg2 Fill	80@99.0078125 (anchor price)
Leg3 Fill	50@99.453125 (anchor price)

Balanced Strip Butterfly

SecuritySubType=BB

The Balanced Strip Butterfly spread is identified by FIX tag 762-SecuritySubType=BB in the MDP3 security definition message; and strategyType=BB in the CME Reference Data API.

The Balanced Strip Butterfly spread will represent a differential spread composed of three legs having equidistant expirations—the near and deferred expirations of a Balanced Strip Butterfly on one side of the spread and twice the quantity of the middle expirations of a pack on the other side (1:2:1). The Balanced Strip Butterfly is aka a "spread of spreads".

A Balanced Strip Butterfly has:

One Product
Three legs
Quantity/side ratio of the legs is +1:-2:+1
Expiration of all legs must be different and symmetric
Legs must be either FS Strip Spread, SB Balanced Strip Spread, AB Average Priced Bundle or SA Strip
Buying a Balanced Strip Butterfly buys leg1, sells 2 * leg2, buys leg3
Selling a Balanced Strip Butterfly sells leg1, buys 2 * leg2, sells leg3

Example

The below example is for illustrative purposes only--using the Average Priced Bundle Packs as the butterfly legs.

Instrument Symbol = SR3:BB U3-U4-U5
- Leg1 = SR3:AB 01Y U3
- Leg2 = SR3:AB 01Y U4
- Leg3 = SR3:AB 01Y U5
