EBS Ai Market Data Request

EBS Ai Standard Header

35=V

262

MDReqID

Y

Correlation ID created by the EBS Ai Client and used to track other messages associated with this request. 

Note 1:  For instruments that are successfully subscribed to, the MDReqID in this message will be carried over to the Market Data Snapshot/Full Refresh.

For instruments that are not successfully subscribed, the MDReqId in this message will be carried over the Market Data Reject message for those instruments.

The protocol does not issue a response for currently subscribed instruments that are later unsubscribed.

Note 2:  EBS Ai does not use MDReqID to track subscriptions.  The EBS Ai Server uses the combined tags Symbol / CFICode / SettlType.

Note 3: For Market Data and Trading Unsubscribe, the EBS Ai Client must provide the same MDReqID which was contained in the message used to subscribe to this instrument.
