Hey, guys, how do I plot rectangles on a standard RSI indicator like this?

I have noticed a grid, colored layers and some small colored spots at the bottom.

Which rectangles are you talking about?

There are standard 30 and 70 lines plotted on RSI.

I used drawing tools and overlayed 2 rectangles, top one starting at 40 Y to 100 Y, bottom one from 60Y to 0Y.

In the source code, it is Plot(New Line.... that plots 30 and 70 lines.

But I cannot find how to plot a rectangle, possibly something like Plot(New Area... - but don't know what that class would be, if any.

That's what I'm asking.

You can use DrawRectangle().

Search the NinjaTrader help file for "DrawRectangle" and you will find the syntax. For example

Code

DrawRectangle("Upper", true, 0, 60, CurrentBar, 100, Color. Red, Color.Red, 4)

should plot you a rectangle for the range 60 to 100.

Seems DrawRegion() might be a better fit here.

@ eDanny:

The problem with DrawRegion is that one of its bounds needs to be an IDataSeries object. The lines of the RSI are not IDataSeries objects, so it will not easily work.

I also prefer DrawRegion() because it paints behind the horizontal lines and not on top.

To use DrawRegion() you would to add an IDataSeries object first. I did not want to make things too complicated, but just suggest a simple solution.
