NT8: What are Order.States that allow to cancel an Order?

[pstrusi]

When a Strategy triggers a signal and submits an order, it will take a time before the Order gets "OrderState.Working" ( accepted and live at the exchange ).

My question is: what if the Strategy needed to cancel that Order before it gets "OrderState.Working" ? Could it be possible to cancel an order in any of these Order.State ?:

OrderState.Accepted
OrderState.PendingChange
OrderState.PendingSubmit

Or even simpler question:
Can a Strategy cancel an order which is " NOT NULL " ?

Thanks

Hello pstrusi,

An order can be cancelled in any state except for Filled, PartFilled, or Cancelled. With these states it would cause an overfill.

Let me know if you would like all the other states than these states listed.

While it is allowed to cancel an order in any other state than these states, there may be other reasons than an order cannot be cancelled (such as improper oco use).

An order variable must not be null and must be assigned an order object for this to be passed to CancelOrder.

However, it would not have state at all, as this would be a variable that does not have any order object at all.

This is also true of NinjaTrader 7.
