OrderCanceled

OrderCanceled represents an order having been canceled at the trading venue. The ExecutionEngine applies it to the order, updates the Cache, and publishes it on the MessageBus. It fires when the venue confirms cancellation of the order.

Transition: PENDING_CANCEL / ACCEPTED -> CANCELED. Handler: on_order_canceled.

Fields

OrderCanceled carries only the common order event fields. On this event, venue_order_id and account_id are usually populated but may be None, and reconciliation carries a real value.

Example

Reading the event in a strategy handler:

def on_order_canceled(self, event: OrderCanceled) -> None:
    self.log.info(f"Order {event.client_order_id} canceled")
