EP093 – Pre trade stream assignment

Standardises the assignment of clients to FX price streams between a price maker and an aggregator. It supports requested and unsolicited assignments, reassignment, termination or unassignment, rejection and acknowledgement. MDStreamID links the assignment to the corresponding Market Data request, snapshot and incremental-update messages, allowing a particular currency-pair, tenor and volume profile, or a broader set of currency pairs, to be identified as a price stream.
