help with bar index error

[Eklavya]

Hi,

I am trying to draw horizontal lines 1.5 times daily ATR above and below the recent close.

I am getting the error "Error on calling 'OnBarUpdate' method for indicator 'ATROnChart' on bar 72: Bar index needs to be greater/equal 0"

I have added a 1440 min data series in the initiatlize procedure with

Add(PeriodType.Minute, 1440);

Here is what I have in the onbarupdate procedure..

double upperLimit, lowerLimit;
			RemoveDrawObject("UpATR");
			RemoveDrawObject("DownATR");
			if (CurrentBar < 72)
				return;
			upperLimit=Close[0]+ATR(BarsArray[1], 14)[0]*1.5;
			lowerLimit=Close[0]-ATR(BarsArray[1], 14)[0]*1.5;
			Print(CurrentBar + ":::" + upperLimit + "::::" + lowerLimit);
			DrawLine("UpATR", false, Time[1], upperLimit, Time[1].AddDays(15), upperLimit, Color.Orange, DashStyle.Solid, 1);
			DrawLine("DownATR", false, Time[1], lowerLimit, Time[1].AddDays(15), lowerLimit, Color.Orange, DashStyle.Solid, 1);

Please try replacing your single series CurrentBar check with this one below and then recheck -

 
if (CurrentBars[0] < 1 || CurrentBars[1] < 1)
return;
