FIX TAG FIELD NAME FIXML PATH FORMAT DESCRIPTION VALUES
10027 SideRegulatoryTradeID /TrdCaptRpt/RptSide/RegTrdID/@ID String Regulatory Trade ID  
10030 SideRegulatoryTradeType /TrdCaptRpt/RptSide/RegTrdID/@Typ Int Position of ID in trade hierarchy 6 - Report Tracking Number

Updated FIX Data dictionary is available for EBS clients.

RegTrdID block will not be populated for trades that are not subject to regulatory requirements, such as EBS Spot.

This change is currently available for customer testing in New Release.

CME STP Support of European Markets Infrastructure Regulation (EMIR) Refit Obligations for CME Cleared OTC IRS/FX - March 24

Effective Sunday, March 24 (trade date Monday, March 25), to support clients with their European Markets Infrastructure Regulation (EMIR) Refit obligations, CME Group will add Post-Trade Risk Reduction (PTRR) ID for trades involved in compression, and begin to pass through Report Tracking Number (RTN), and PriorUTI (Prior Unique Transaction Identifier) in CME STP when they are available for CME-cleared OTC IRS and OTC FX trades.

Identifier Description
Report Tracking Number (RTN) Where a derivative was executed on a trading venue, a number generated by the trading venue and unique to that execution.
Post-Trade Risk Reduction (PTRR) ID Identifier generated by the PTRR service provider or CCP providing the PTRR service in order to connect all derivatives entering into a given PTRR event and resulting from that PTRR event.
PriorUTI (Prior Unique Transaction Identifier) Assigned to the predecessor transaction that has given rise to the reported transaction due to a lifecycle event, in a one-to-one relation between transactions (e.g. in the case of a novation, when a transaction is terminated, and a new transaction is generated) or in a one-to-many relation between transactions (e.g. in clearing or if a transaction is split into several different transactions). This data element is not applicable when reporting many-to-one and many-to-many relations between transactions (e.g. in the case of a compression).

These identifiers will be populated: 

  • In the field: 
    • FIX: tag-10027 SideRegulatoryTradeID
    • FIXML: /TrdCaptRpt/RptSide/RegTrdID/@ID 
  • Of the Trade Capture Report (FIX: tag 35-MsgType=AE , FIXML: /TrdCaptRpt) within the repeating group:
    • FIX: SideRegulatoryTradeIDGrp
    • FIXML: /TrdCaptRpt/RptSide/RegTrdID
