EP010 – Execution Acknowledgement

Proposes an optional Execution Acknowledgement message through which an initiator or buy-side firm can explicitly accept or reject execution details received in an Execution Report. It supports executions arising from FIX orders and orders placed through non-FIX channels, such as telephone or a platform interface. It combines positive acknowledgement and DK-style rejection functionality without replacing the existing Don’t Know Trade message for firms already using it, and it also supports acknowledgement of corrected executions.
