FIXMsgType 35=9

Order Cancel Reject (35=9)

FIX 4.4 Gateway TLS/TCP

The server sends OrderCancelReject (35=9) to the client over TLS/TCP. This is not an HTTP response.

Sent when an OrderCancelRequest cannot be fulfilled. For example, the order is already filled, already canceled, or unknown.

CxlRejResponseTo (434) is always 1 (OrderCancelRequest).

CxlRejReason (102) Meaning
0 Too late to cancel. Order already filled, canceled, or pending cancel
1 Unknown order. OrigClOrdID (41) or OrderID (37) not found
99 Other. System error, account mismatch, or non-cancelable state (see text 58)
