OrderEmulated

OrderEmulated represents an order having become emulated by the Nautilus system. The ExecutionEngine applies it to the order, updates the Cache, and publishes it on the MessageBus. It fires when the OrderEmulator takes an order under local emulation.

Transition: INITIALIZED -> EMULATED. Handler: on_order_emulated.

Fields

OrderEmulated carries only the common order event fields. On this event, venue_order_id and account_id are both None, reconciliation is always False, and ts_event equals ts_init.

Example

Reading the event in a strategy handler:

def on_order_emulated(self, event: OrderEmulated) -> None:
    self.log.info(f"Order {event.client_order_id} is now emulated locally")
