wow great job @samer800 like always, quick add on if is possible, do you think price color with signals? thanks in advance

oh may not explain well. what i mean is, if is a buy signal paint the candles let say blue, if is a short signal paint the candles magenta.

add the line at the end of the code.


AssignPriceColor(if sell then Color.MAGENTA else if buy then Color.CYAN else Color.CURRENT);
