Sorry if you have already discussed this topic (I searched but couldn't find it) or it's a very noob question.
I would like to color the area between 70 and 30 on the RSI graph for each stock.
I tried to color the RSI area between two horizontal lines with the following help (https://www.amibroker.com/kb/2007/03/17/how-to-fill-the-area-between-two-lines-with-a-solid-color/comment-page-1/) but this code didn't work for me even though I copied it. In addition, even though I draw a horizontal line the other stocks do not appear automatically. Could someone possibly help or help where I can find a solution to this?
Thanks for the answers!
