NinjaTrader crashes when I load strategy with CancelOrder()

[leontancfa]

The script is approx. like below. I had no problem before adding CancelOrder() and IOrder. Don't know which caused the crash. Could you have a look?



private IOrder myEntryOrder = null;
private int barNumberOfOrder = 0;

protected override void OnBarUpdate()
{

{

myEntryOrder = null;

myEntryOrder = EnterLongLimit(0, true, 1, Low[0], "Long Entry");
barNumberOfOrder = CurrentBar;
}


if (CurrentBar > barNumberOfOrder + 3)
CancelOrder(myEntryOrder);
}
