CPT FIX to CME STP

Introduction

This topic is for users migrating from the EBS Central Post Trade (CPT) FIX API to the CME STP API. CME STP supports FIX and FIXML API. Mappings apply to both APIs and provide CPT FIX equivalent fields in the CME STP that should be used with the CME STP documentation in related resources.

CME STP is the strategic solution for CME Post Trade services based on the industry standard FIX and FIXML protocol.

Overview

CPT FIX and CME STP FIX are both based on FIX 4.4, which should make the migration relatively straightforward; there are some key differences between the APIs.

Subscription, Configuration and format changes

The table below describes differences in Session management between CME STP FIX and CPT FIX. FIXML is a different session protocol so it is inherently different to CPT FIX, CPT does not support FIXML and not compared in the table below.

CPT FIX

Initialisation

Logon must always have tag 141-ResetSeqNumFlag=Y to reset sequence numbers with every session. Sequence numbers are not needed for recovery as client systems use TradeCaptureReportRequest (tag 35-MsgType=AD) for subscription or recovery of tickets. 

Logon must never have tag 141-ResetSeqNumFlag=Y (either omit or set to "N") as persistence is integral to recovery following a disconnection. 

Subscription

Client systems send a TradeCaptureReportRequest (tag 35-MsgType=AD) with tag263-SubscriptionRequestType=1 to initiate a subscription for tickets.

There can be only one subscription per established FIX Session.

Tickets are sent as soon as a session is connected and tickets are available

Recovery

Client systems can use TradeCaptureReportRequest (tag 35-MsgType=AD) with tag263-SubscriptionRequestType=0 to initiate trade recovery.

CPT uses FIX Session recovery to send messages that were not sent previously, user has no ability to re-request a message already sent.

Configuration/Filters

Client systems can use filters defined in TradeCaptureReportRequest (tag 35-MsgType=AD) to limit the scope of returned tickets. Different filter parameters are applicable to Subscription or Recovery request.

CPT is configured by CME and changes are only applied on the weekend

Message format

The TradeCaptureReport is a single sided message

The TradeCaptureReport is a two-sided message.



CPT FIX to CME STP FIX Mappings

A large difference between the CPT FIX message and the CME STP FIX message is the use of the sides group. On CPT FIX there were always 2 sides to the message with side 1 reflecting party 1 in the trade and side 2 reflecting party 2 (the counterparty). On CME STP there is one side and instead the 2 parties are represented by specific PartyRoles. The PartyRole mapping is handled in a separate table below this main one.

571

TradeReportID

Unique Identifier of the TradeCaptureReport. 

Used to identify duplicate tickets. 

Y

Y

571

TradeReportID

RptID

Same usage as CPT FIX.

Used to identify duplicate tickets. 

Note, when supported, Amends and Cancels will have a new TradeReportID value.

1003

TradeID

Deal ID, the globally unique EBS identifier for the trade.

Y

Y

1003

TradeID

TrdID

Same usage as CPT FIX

For relating to the trading APIs this maps to:

  • tag 17 on ER from Ai

  • tag 1797 on ER from iLink

  • tag 17 on ER from EBS Direct LC API

  • tag 11 on NOS to EBS Direct LP API

This is the unique deal ID that is common to the maker and taker. For Prime Banks that consume 2 tickets per trade the ticket ID (571) will be unique but the trade ID will be common. 

1040

SecondaryTradeID

LP assigned Trade Identifier. Up to 64 characters.

For LCs this field contains the same value as field 527, SecondaryExecID, on the FIX 4.4 API Execution Report. (Relevant only for MarketID=FXQDM.)

Y

N

527

SecondaryExecID

ExecID2

Only provided for EBS Direct disclosed tickets to LCs. Provides the LP's ExecID in the ER returned to EBS Direct by the LP.

For relating to the trading API it is mapped to:

  • tag 17 on ER from EBS Direct LP API

Note: 1040 on CME STP has a different ID with different meaning.

829

TrdSubType

The only valid value for this tag is “40” (Wash Trade)

N

N/A

99103

PostTradeType

PostTrdTyp

On CPT this indicated the Prime Broker (and Prime of Prime) Synthetic tickets only. 

On CME STP this maps to value 4 - Prime Give Up (Synthetic) tickets.

Note that Prime Customers will also see value 4 (as that is a Synthetic ticket) so 829=40 maps to 99103=4 only for Prime Broker and Prime of Prime Broker Synthetic tickets. To programmatically differentiate between Prime Customer Synthetic tickets and Prime (and Prime of Prime) Broker Synthetic tickets please use PartyRole 79, which is only present on tickets to Prime (and Prime of Prime) Brokers.

150

ExecType

Describes the purpose of the TCR.
Values:
F = Trade (standard trade)

For eFix, clients have the option of receiving a reference ticket at the time of the match, followed by a restated ticket when the trade price is fixed. These will be reported with the following ExecTypes: 
z  =  Reference Trade (Match-time eFix ticket containing a reference rate.) - custom value
D = Restated (updated eFix ticket containing the fixing rate)

If the client opts to wait until after the fixing for the eFix ticket to be issued, then they will receive a single standard eFix ticket. (ExecType=F).

In future releases, additional ExecType values will support trade corrections and cancels.

N

N/A







CME STP does not provide match tickets, for eFix there is no equivalent of this tag on CME STP.

572

TradeReportRefID

When providing a 2nd eFix ticket (a restated trade) this is a reference to the TradeReportID of the original (match time) ticket. It is only provided on the 2nd eFix fixing ticket.

N

N/A







CME STP does not provide match tickets, for eFix there is no equivalent of this tag on CME STP.

Party ID Mappings - CPT FIX to CME STP 

In general there are direct mappings between the CPT Party Group PartyID tag (tag 448), which is defined by supporting tags PartyRole (tag 452) and PartyIDSource (tag 447), and the CME STP Party Group PartyID tag (tag 449). The same is true for the PartySubID (tag 523), which is defined by the PartySubIDType (tag 803). In some cases CME STP does not support the same PartyRole/PartyIDSource anymore. This detail is shown in the table below.

There are a few places where there is no mapping between the Party/PartySubID groups in CPT FIX to CME STP FIX, which are noted in this main mapping table and the detailed mapping is provided in the table below it. 

It is worth pointing out one main difference, in CME STP party role 7, (the Trading Firm) is used to create the Request and provided in the TradeCaptureReport. It is equivalent to tag 1 (Account) on side 1 of the CPT ticket. The side (tag 54) and AggressorIndicator (tag 1057) both apply to the TradingFirm only (and so will 'flip' on the Synthetic tickets).
