I successfully applied Draw.Regoion() function to put my Bollinger Band as background shadow in the main panel (Panel 1).
However, when I tried to apply Draw.Region() / Draw.Retangle() in the standalone indicators, e.g. MACD-v in Panel 2/3, the function shows no error, but the shadows appears in Panel 1, instead of Panel 2/3.
Does these functions can be easily modified in order to function properly in the future release?
This kind of trick can be easily done in TradingView.
No. I did not.
I believe in the standard syntax, there is NO such parameter to choose panel, because MACD-v can appear in any panel other than Panel 1.
But I will give it try.
It works.
Actually It turns out that Draw.Retangle() does have such an DrawOnPanel option in one of those function listed, while Draw.Region() does NOT.
now the MACD-v indicator looks much less crowdy.
thank you so much.
