DrawEllipse

[BradB]

How can I draw an Ellipse around the current bar if I want to leave any space on either side of the bar?

For example:

DrawEllipse("mytag", CurrentBar-2, High[0], CurrentBar+2, Low[0], Color.Black)

will give me an error about startBarsAgo being greater or equal to zero. In order to circle the current bar, it has to be.

Any suggestions? Am I missing something?

Thanks.

The parameters are looking for "bars ago" and not the bar number. So instead of using CurrentBar - 2 just put in 2.

That doesn't help me. Specifying 2 only draws on the left side of the current bar. You can't specify a negative number (-2) for the right side of the current bar, hence, I can't draw an ellipse around the current bar, right?

Unfortunately this is not possible at this time.

Unfortunately this is not possible at this time.

I'm trying this:

DrawEllipse("ellipse"+CurrentBar,true,(indexa-1),High[indexa]+5*TickSize,(indexa+1),Low[indexa]-5*TickSize,Color.Navy,Color.Gold,3);

Any way to draw this without the error apparently induced by the

(indexa+1)

??

Hello zeller4,

Thank you for your post.

You could use the following but keep in mind the -1 value would need a bar to pull from so this would need to be when using CalculateOnBarClose = true:

			if (CurrentBar <= 1)
				return;
			
            DrawEllipse("tag", 1, Close[1], -1, Close[-1], Color.Black);

You may wish to look into custom drawing. An example can be found under Tools > Edit NinjaScript > Indicator > CustomPlotSample. This shows how to override the Plot method for custom drawing.
