RSI21 drops below lowest bollinger 20 band

[rsy]

I am using the formula wizard and want the background to be green whenever RSI21 drops below lowest bollinger20band.
What is wrong here?

What do you mean by What is wrong here?
It appears that the background is being painted when the condition you set is verified (see image)

I had to unload and reload the formula. It works..
But I want the formula to plot a green dot at the bottom in the RSI-windows instead.

I tried with

drawShapeRelative(0, 10, Shape.CIRCLE, "", Color.RGB(0,255,0), Shape.BOTTOM)

...but it did't work.

That is a command that is not yet available in Formula Wizard.
You can however do it using the Editor as you can see in the attached efs and image.

Thanks again Alex.

I just edited the following line in formulawizard

drawShapeRelative(0, 10, Shape.CIRCLE, "", Color.RGB(0,255,0), Shape.LEFT

to

drawShapeRelative(0, 10, Shape.CIRCLE, "", Color.RGB(0,255,0), Shape.RELATIVETOBOTTOM)

It works well!
