Bar Index

[lookOutBelow]

I'm getting this error when trying a multi time frame strategy. I'm not sure why. Any explanation what this means? I'm not sure what is causing this problem.

**NT** Error on calling 'OnStartUp' method for strategy 'xxxa': Bar index needs to be greater/equal 0

Thanks

Hello,

Thanks for your note.

Can you please post your OnStartUp() code and Initialize() code?

I look forward to assisting you further.

Sure,

protected override void OnStartUp()
		{
			PrintWithTimeStamp("started: " + DateTime.Now);
		}
		
		
		
        protected override void Initialize()
        {	
			if (AddIndicators == true)
			{
				Add(VOL());
			}

            CalculateOnBarClose = true;
			TraceOrders = false;
			Unmanaged = true;
			//RealtimeErrorHandling = RealtimeErrorHandling.TakeNoAction; 
			
			Add(PeriodType.Second, 5);
}

Hello,

Can you try changing PrintWithTimeStamp() to just Print() just in OnStartup()

I was not able to duplicate on my side though. If you make this change and you still have issue I would need to have you send full code to support at ninjatrader dot com since I added the above to a test strat and no errors where thrown.

Let me know if I can be of further assistance.

That seemed to have fixed it. Weird! Why would a PrintWithTimeStamp be a cause for that?

humm.

Thanks though!

Hello,

PrintWithTimeStamp grabes the time stamp from the Bar Series Time[0]. Therefor in OnStartUp() the BarSeries does not exist yet therefor this coudl fail as a race condition.

Let me know if I can be of further assistance.
