Tags conflict - DrawArrow...?

[Art09]

Hi,
The arrow is not drawn on the chart when calling Draw arrow...

public class ...Blah...: Indicator
{
#region Variables
.........
...........
string arrowDn = "DnArrow";
..........
..........

When I call DrawarrowDown() in OnBarUpdate:
DrawArrowDown(arrowDn + CurrentBar, true, 0, (MAX(High, 5)[0]+arrowPos), Color.White); - I see no arrow.

But if I replace arrowDn with hardcoded "MyArrowDn" as below - it works.
DrawArrowDown("MyArrowDn" + CurrentBar, true, 0, (MAX(High, 5)[0]+arrowPos), Color.White);

Is there tag conflict or such?
Thank you.

Art09, which version of NinjaTrader are you using? I just tested on RC1, and both arrows show up.

Hello,

Thanks for the further information.

Please try "MyArrowDn" + CurrentBar.ToString(); to see if that will make a difference here.

I look forward to assisting you further.
