When IOrder can get to state OrderState.Unknown ?

[misova]

Can you provide some real example, how/when can happen,
that order gets into state OrderState.Unknown?
I expect, that only rational handling of this state in reporting error, stop strategy and ask for manual intervention. Or can this Unknown state change back to some valid state automatically?

Hi misova,

The unknown state is generally because something has happened.
One possibility is there may be a disconnection and and order fills or changes state and when the connection comes back the brokerage does not send a status update for the order.

If the brokerage sends another status update for the order such as cancelled, filled, etc this may bring the order into a working state.

However, typically manually disconnecting and reconnecting will correct these orders as NinjaTrader will poll the brokerage for order states for orders made that day.
