The purpose of the in-flight order check is for live reconciliation, events emitted from the venue may have been lost at some point - leaving an order in an intermediate state, the check can recover these events via status reports.

• Parameters:
  • reconciliation (bool , default True) – If reconciliation is active at start-up.
  • reconciliation_lookback_mins (NonNegativeInt , optional) – The maximum lookback minutes to reconcile state for. If None or 0 then will use the maximum lookback available from the venues.
  • filter_unclaimed_external_orders (bool , default False) – If unclaimed order events with an EXTERNAL strategy ID should be filtered/dropped.
  • filter_position_reports (bool , default False) – If position status reports are filtered from reconciliation. This may be applicable when other nodes are trading the same instrument(s), on the same account - which could cause conflicts in position status.
  • inflight_check_interval_ms (NonNegativeInt , default 2_000) – The interval (milliseconds) between checking whether in-flight orders have exceeded their time-in-flight threshold. This should not be set less than the inflight_check_interval_ms.
  • inflight_check_threshold_ms (NonNegativeInt , default 5_000) – The threshold (milliseconds) beyond which an in-flight orders status is checked with the venue. As a rule of thumb, you shouldn’t consider reducing this setting unless you are colocated with the venue (to avoid the potential for race conditions).
