At the request of customers, beginning October 30, 2016, for trade date October 31, 2016, CME Clearing will add a new FIXML “Party Detail” block to some CME ClearPort trade confirmations that are sent to Clearing Member Firms (CMFs) from Front End Clearing (FEC) via MQM. The new Party Detail block will contain the sub-accounts related to the account specified in Party Role 24. It will only appear when the trade is entered into ClearPort with the sub-account specified.
As this is an entirely new block being added to the FIXML messages, firms may elect to ignore or process it as needed. The new Party Detail block will appear immediately following normal Party (“Pty”) blocks.
