OrderState.PendingCancel

[jp_kettunen]

When cancelling an order, exactly when does OrderState update to OrderState.PendingCancel? Immediately after sending CancelOrder, or does NT first need to receive some sort of acknowledgement from the broker or from the exchange?

Second, if everything proceeds well, is it possible for the order to reach OrderState.Cancelled without first reaching OrderState.PendingCancel?

Third, can one expect different behaviour on live and Sim accounts? Asking this because the code below may sometimes print "Cancelling buy" dozens of times before the order gets cancelled on Sim. Haven't noticed this when trading live.

if (buyOrder != null)
{
if (buyOrder.OrderState != OrderState.PendingCancel)
{
Print("Cancelling buy");
CancelOrder(buyOrder);
}
return;
}

Hi,

1) An order is set to state PendingCancel as soon as you cancel the order within NinjaTrader and before the cancel request is sent to the broker/exchange.

2) An order will always follow the sequence PendingCancel, Cancelled if everything proceeds well.

3) I believe the behaviour should be the same. I would change your code to print out the order state to see when your code executes. PendingCancel state in theory should only be set once for the lifetime of an order.
