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);
}

I tested it in my another machine, and it still crashes when I load the script.

Please chech the log tab for errors when this happens.

You don't want to reset your IOrder entry order object to null each time the OnOrderUpdate() is called, so just check if it's null and then place the entry -

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

strange that I deleted the whole IOrder codes from my script, and it still crashes. Does NinjaTrader have memory or sth?

I found that it's not my particular strategy cause the crash now. I went to Strategy tab, right click, new strategy, and then NT crashes.

But before I used the IOrder script, NT was fine running any strategy.

leontancfa,

After making any changes to code you will need to recompile and also start a new instance of the script. We will need more information on what you mean by "crash". Please provide trace/log files.
