Active drawing object tag names must be unique per drawing tool type error

[ballboy11]

I have this error for my indicator and I don't understand why I added this before redrawing.


RemoveDrawObject("Tangle"+ nTriangleCount.ToString());

Draw.TriangleDown(this, "Tangle" + nTriangleCount.ToString(), true, 16, High[0]+ 1 * TickSize, Brushes.Tomato);
nTriangleCount++;


I still receive this error.
Am I not using Remove draw object properly?

Hello

Thank you for the post.

I am not seeing this error while testing this code specifically, have you tested this in a separate file to confirm you still get the same message?

This is the test I conducted and see it drawing and no errors:

int nTriangleCount = 0;
protected override void OnBarUpdate()
{
	if(CurrentBar < 20) return;
	RemoveDrawObject("Tangle"+ nTriangleCount.ToString());

	Draw.TriangleDown(this, "Tangle" + nTriangleCount.ToString(), true, 16, High[0]+ 1 * TickSize, Brushes.Tomato);
	nTriangleCount++;			
}

Also, I noted that you are incrementing the count in this sample, but the next iteration of OnBarUpdate you are accessing the incremented count for the removal. Are you intending on removing the last object? If so did you mean:

RemoveDrawObject("Tangle"+ (nTriangleCount - 1).ToString());

I look forward to being of further assistance.
