Colour the watchlist with if then

Thank you Pete for the custom watch list video. I was able to create a watchlist that brings up my scan but I can’t find a way to colour the two findings in different colours.

//This part I can’t figure out

def clsAbove = SimpleMovingAvg(“length” = 22).”SMA” crosses below close;
def clsBelow = SimpleMovingAvg(“length” = 22).”SMA” crosses above close;

//

plot signal = SimpleMovingAvg(“length” = 22).”SMA” crosses below close or SimpleMovingAvg(“length” = 22).”SMA” crosses above close;
AssignBackgroundColor(if signal then color.DARK_GREEN else color.WHITE);

What I’m trying to do is if clsAbove is true the BackgroundColor is Green if clsBelow is true it is Red.

I can’t figure out the if-then logic as I don’t know enough of the syntax to figure it out.
