Order Cancel Request <F>

The Order Cancel Request <F> message requests the cancellation of all of the remaining quantity of an existing order.

Gemini cancels order on the basis of the value in the OrigClOrdID <41> field. All other fields are required in the FIX specs but will be disregarded.

  • if the order can successfully be canceled before being completely filled, an Execution Report <8> with ExecType <150> set to 4 = Canceled
  • if the request fails, an Order Cancel Reject <9> message with CxlRejReason <102> of 1 = Unknown order
