Question:

It is not clear to me from the FIX 4.0 which client order ids need to be used by the sell-side while responding to cancel and cancel/replace requests. here is my interpretation and correct me if I am wrong.

BUY-SIDE SELL-SIDE (exec rpt)

New Order New Order Ack
ClOrdId=ORD1 ClOrdId=ORD1

                       New Order Reject
                       ClOrdId=ORD1

Cancel/Replace Cancel/Replace Reject
ClOrdId=ORD2 ClOrdId=ORD1
OrigClOrdId=ORD1

                       Cancel/Replace Pending
                       ClOrdId=ORD1
                
                       Cancel/Replace Ack
                       ClOrdId=ORD2

Cancel Cancel Reject
ClOrdId=ORD2 ClOrdId=ORD1
OrigClOrdId=ORD1

                       Cancel Pending
                       ClOrdId=ORD1
                   
                       Cancel Ack
                       ClOrdId=ORD2

According to Appendix D of the Spec and descriptions of Execution and CancelReject messages ClOrdID in these messages indicates the id of last action on the order, that means ClOrdID of Cancel(Cancel/Replace) requests.

Therefore in your example for Cancel and Cancel/Replace all responses should have ClOrdID=ORD2 and OrigClOrdID=ORD1.
