IFF and colors

Hi,
I am a bit lost..Here is my formula which i believe to be correct.Normally I would use the IFF function to chart different colors for RS<>0

Color=iff(rs>0,colorgreen,colorred)'

How do I do it in quantshare??

symbol="spy";
a=getseries(symbol,close);
x=a-ref(a,-21);
x1=x/ref(a,21);
y=close-ref(close,21);
y1=(y/ref(close,21))*100;
rs=y1-x1;

You should use the "UpdateColor" function. "Iff" function gets numeric vectors only.

As described in the above article, the "UpdateColor" function should be used just after "Plot".

Example:
Plot(rs, "", colorGreen);
UpdateColor(rs <= 0, colorRed);
