Change Summary
Mandatory Change
Background
ExecutionAcknowledgement/ 35=BN is commonly supported by most ECNs to ACK or NACK the client ExecutionReport. MarketFactory considers the ExecAck as the end of the trade life cycle on the maker workflow (where the MF clients are the market makers).
However, Integral does not send an ExecutionAcknowledgement to notify that the client ExecutionReport is accepted or rejected.
MarketFactory will introduce a synthetic ExecutionAcknowledgement
