The Execution Report Acknowledgement message is an optional message that provides dual functionality to notify a trading partner that an electronically received execution has either been accepted or rejected (DK'd).
The DK portion of this message does not replace the existing DK Trade message for users who have already implemented the DK Trade message. For users who have not implemented the DK Trade message, through this single message they will be able to accept and DK an execution report. Users who wish to continue to use the DK Trade but also want a means to explicitly accept an execution report can also use this message to accept the execution report.
