OrderTriggered

OrderTriggered represents an order having been triggered at the trading venue. The ExecutionEngine applies it to the order, updates the Cache, and publishes it on the MessageBus. It fires when a trigger condition is met for a limit-style conditional order (StopLimit, LimitIfTouched, or TrailingStopLimit).

Transition: ACCEPTED -> TRIGGERED. Handler: on_order_triggered.

Fields

OrderTriggered 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:

python
def on_order_triggered(self, event: OrderTriggered) -> None:
    self.log.info(f"Order {event.client_order_id} triggered")
  • Events - Event categories, dispatch, and the common order event fields.
  • Orders - Order types and the state machine.
