FIX 4.0 : Order Cancel Request <F> message

Structure | Related Messages

Description

The Order Cancel Request <F> message is used to request the cancellation of all or part of the remaining quantity of an existing order. The CxlType <125> field is used to distinguish if all or part of the outstanding quantity is to be canceled.

Although the Order Cancel Request <F> message can be used to partially cancel (reduce) an order it is recommended that the Order Cancel/Replace Request <G> message be used for that purpose.

The request will only be accepted if the order can successfully be pulled back from the exchange floor without executing.

Note that a cancel request is assigned an order id and is treated as a separate entity. If rejected, the order id of the Cancel Request will be sent in the Cancel Reject <9> message. The OrderID <37> assigned to the cancel request must be unique amongst the OrderID <37>'s assigned to regular orders and replacement orders.
