The Trade Capture Report needs to carry the following references
1) ExecID [17] to point to the Execution Report Trade;
2) OrdID [37] to point to the exchange / broker associated ID - from client's prospective this is possibly a chain of order ammendments;
3) ClOrdID [11] as the associated order has been submitted electronically.
Honoring the ClOrdId [11] an providing the matching the value with the original execution report has advantage of
1) unambiguously pointing to the appropriate link in the chain of ammendments made by client.
2) avoids race conditions in synchronizing back office sub-system with real-time trading / matching engine. Depending on the time Trade Capture Report is issued (if the client order is still alive) the current value in tag 11 may refer to any link in the chain and not necessarily be the last in the lifetime of the order. More over, the matching engine may be in he process of handling Cancel Replace request.
