@JediStar Depending on whether you want the foreground or background color changed:
AddColumn(PercentR(20), "WilliamsR", 1.2, IIf(PercentR(20)<-80,colorRed,IIf(PercentR(20)>-20,colorLime,colorGrey50)));
AddColumn(PercentR(20), "WilliamsR", 1.2, colorDefault, IIf(PercentR(20)<-80,colorRed,IIf(PercentR(20)>-20,colorLime,colorGrey50)));
AddColumn(PercentR(20), "WilliamsR", 1.2, IIf(PercentR(20)<-80,colorRed,IIf(PercentR(20)>-20,colorLime,colorGrey50)));
AddColumn(PercentR(20), "WilliamsR", 1.2, colorDefault, IIf(PercentR(20)<-80,colorRed,IIf(PercentR(20)>-20,colorLime,colorGrey50)));
Thanks a mil bro, much appreciate your time at this part of the night.
