When the buyside sends in a new order, they include their identifier (tag 11). The sellside response (an execution report) contains both the buyside identifier (tag 11) and the sellside identifier (tag 37). Is there something similar for allocations?
I know that tag 70 is the buyside identifier but is there any tag for the sellside to identify the allocation when sending back the allocation ack?
In FIX versions 4.0 to 4.3 the sellside Allocation Ack basically echos back the AllocID provided by the buyside in the Allocation message.
When the sellside provides a “calculated” allocation message back to the buyside, the AllocID would contain the sellside’s identifier while the RefAllocID would contain the buyside’s allocation identifier.
FIX 4.4’s support for allocations moved to implement the more familiar ClOrdID / OrderID style found in the New Order and Execution Report message types.
