Hello,
I need help for a problem with FIX 4.0 and USA Market
The scenario is:
I sent an order to a broker and I have back an execution (total or partial); after that the broker replaces the execution with another one (total or partial), because it’s a “best execution” for me.
How can I know that this second one replace the first one?
There is a sequence of messages we need to use? And wich ones?

Thanks for all

Should be an ExecutionRpt with ExecTransType=2 (Correct) vs. =0 (New). Note ExecRefID will specify the ExecID which it is correcting/replacing.
