hey vince.... that might depend on which indicator we're talking about.... as a rule the indicators can be broken into differing colors at any point, which includes 0...... you'll just need to break the indicator into 2 or more plots..... that way you can click on one and change its color..... below is a very quick and sloppy example of rsi changing colors at the 50 level.... click on the plot above 50 and change to green..... 0 based oscillators naturaly would work best..... again, thats a crude example, that can be vastly improved and expanded to include more facets.....h [code:1:8ad7637769]a:=RSI(14); b:=RSI(14); aa:=If(RSI(14)>50,a,50); bb:=If(RSI(14)<50,b,50); aa;bb;[/code:1:8ad7637769]
