XCDE will respond with an OrderCancelReject message when it receives a Cancel Request or a cancel/replace request message which cannot be honoured. Requests to change price or decrease quantity of an Order are possible only when an outstanding quantity exists.

When rejecting a Cancel/Replace Request (or Cancel Request), the Cancel Reject message will provide the ClOrdID which was specified on the Cancel/Replace Request (or Cancel Request) message for identification, and the OrigClOrdId should be that of the last accepted Order message (except in the case of CxlRejReason = “Unknown Order”.

To accept CancelRequest and cancel/replace request messages, XCDE will send an simple ExecutionReport message.
