Common Customer GatewaySM (CCG) support to return an order originator’s “SenderCompID” information on Drop Copies.
This notice updates the Trader Alert distributed on June 7th, 2011 announcing the NYSE’s ability to accept a Sender’s MPID information on all order and cancel with replacement messages destined to the NYSE Broker Systems. Based upon customer feedback, the NYSE will make the following additional change to Order Drop Copy messages commencing on or before October 3rd, 2011.
Broker System Destined Orders:
For customers who subscribe to Order Drop Copy services, these messages will now return the original order “SenderComplD” (FIX Tag 49) in FIX Tag 50 (SenderSubID) on drop copy messages. FIX Tag 49 (SenderCompID) will continue to be populated with the Drop Copy connection ID as it does today. For customers that populate Tag 50 (SenderSubID) on an incoming order, we will overwrite this information on any Order Drop Copy message returned with the original order “SenderCompID”. In addition, for any orders entered directly into the NYSE Broker Booth Support System®, the “SenderSubID” field will not be populated.
Please note that the original order “SenderComplD” will not be returned on any outgoing messages (message Type 8) from the NYSE received over a drop copy connection. This includes order acknowledgments, UROUT and report messages.
Matching Engine Destined Orders:
For orders or cancel with replacement messages destined to the NYSE Matching Engine, there are no drop copy changes being made as a part of this enhancement.

The NYSE UAT testing environment will be available beginning week of August, 29th, 2011. Please contact Firm Testing Services at firmtesting@nyx.com or 888.689.7739 Option 2 to schedule testing.
