Execution Reports - Cancels

Pending cancel and canceled execution report message formats and fields.

Execution Reports – Cancels

After submitting an Order Cancel Request, Paxos sends two Execution Reports confirming the cancellation process:

• Pending Cancel (ExecType (150) = 6) — Acknowledgement that the cancel request was received.
• Canceled (ExecType (150) = 4) — Confirmation that the order has been canceled.

A Pending Cancel is not a guarantee of cancellation. The order may fill before the cancel is processed. If cancellation fails, an Order Cancel Reject is returned instead.
