Remove object outline

[rangerdoc]

I have an NT7 indicator that uses drawdiamond & drawtriangle. There are times when I don't want the diamond, only the triangles.
The problem is that if I set the diamonds to transparent, there is still a black outline. Transparent only clears the fill of the object, not the outline.
Is there a way I can get the outline of objects transparent or remove alltogether?

Thanks

Hello Rangerdoc,

Have you tried using RemoveDrawObject()?

Why not take the approach of using a boolean variable (defined as a Property), to control the drawing of the diamond in the first place?
