IDrawingTool.EndAnchor.SlotIndex not working in Strategy Analyzer

[awesometrader]

Hi,

I need to draw a horizontal line that starts at a certain bar in the past and ends at the CurrentBar. I've used Draw.Line to draw the line initially, then I am using line.EndAnchor.SlotIndex += 1; to update it to the CurrentBar.

That works in the Chart, however it does not work properly in the Strategy Analyzer. When debugging, the value of SlotIndex is set to -2147483648, which is Integer.MinValue.

What is a reliable way to achieve what I am trying to do in both environments?

Thanks

Hello awesometrader,

Thanks for your post and welcome to the NinjaTrader forums!

I would recommend saving the start bar into an int variable and then just using that in the Draw.Line() method where you would use the variable name for the start bar, use 0 for the current bar and keep the "tag name" the same so that on each on bar update, the line is automatically removed and redrawn with the new current bar.

Thanks, that worked!
