Silver Calendar Spreads
The CME Globex platform lists both outright futures and calendar spreads for Silver. The Strategy Type Code 'RT' supports Silver calendar spreads as defined in tag 762-SecuritySubType of the Security Definition (tag 35-MsgType=d) message.
The Silver calendar spread is constructed: Leg 1 – Leg 2 = Spread.
Spread Type | Leg 1 | Leg 2 | Calendar Spread Pricing |
|---|---|---|---|
RT | Buy | Sell |
|
Silver spreads have the following processing rules:
Silver calendar spreads trade in tick increments of 1.
Last Best Price data block in Market Data Incremental Refresh (tag 35-MsgType=X) messages are disseminated for the spread but not for the legs.
Trade data blocks are not disseminated for legs due to spread trades. Volume will be updated on subsequent Market Data Incremental Refresh messages due to outright trades on the legs.
Trade data blocks are disseminated for the actual outright spread trades.
Settlement prices for all futures and spreads tick in increments of 1.
| Info |
|---|
When a Settlement price on a Leg is in an increment of 1 and no Last Best Price is created for the next day, an order submitted with a price of "Last" will be rejected with the error "Invalid tick price", since the outright legs tick in increments of 5. |
...
Calendar spread trades with the strategy type of 'RT' use the leg with the most recent trade price as the anchor.
If the most recent trade price is in leg 1, then the formula is: Leg 2 = Leg 1 (Anchor) – Spread Price.
If the most recent trade price is in leg 2, then the formula is: Leg 1 = Leg 2 (Anchor) + Spread Price.
If there is no trade price available in either contract, the leg with the most recent settlement price is the anchor for pricing calculations.

Implied IN Pricing Example
There is a Bid in SIZ6 at 13955.
There is an Ask in SIG7 at 14025.
This creates an Implied IN Bid in the Silver calendar spread SIZ6-SIG7 at -70.
...
Implied OUT orders from calendar spreads in the Silver futures are generated by calculating the price of a leg from resting Bids or Offers in the other outright futures contract and the actual resting bid or offer in the Silver calendar spread.
Implied OUT orders in the Silver futures are disseminated.
Implied OUT orders in the Silver futures are generated at standard tick increments.
Implied Bid prices are always rounded down.
Implied Ask prices are always rounded up.
Implied OUT Bid Rounding from Calendar Spreads Example
There is a Bid in SIZ6 at 13955.
There is an Ask in the Silver calendar spread of SIZ6-SIG7 at -74.
This creates an Implied OUT Bid in SIG7 at 14029.
All implied OUT bids are rounded down to the next standard tick.
Implied OUT Bid is created in SIG7 at 14025.
Implied OUT Ask Rounding from Calendar Spreads Example
There is an Ask in SIZ6 at 13955.
There is a Bid in the Silver calendar spread of SIZ6-SIG7 at -74.
This calculates an Implied OUT Ask in SIG7 at 14029.
All implied OUT asks are rounded up to the next standard tick.
Implied OUT Bid is created in SIG7 at 14030.
Due to the rounding of implied OUT orders, resting orders may receive fills at prices fractionally better than that at which they were displayed.
