Hello aytacasan,

There is a different approach depending on version.

Version 6.5 - See multi color plot approach for version 6.5 here.

Version 7 - See multi color plot approach for version 7 here.

Sory you are right, i have to indicate which version i'm using. I developing my indicators at Ninja 7. So i can use multi color plot approch, i know it too. But this example i don't have a plot i have a line. (Like Indicator wizard last step). If you mean never mind add a line vice add plot for zero line level and adjust its color via PlotColors. Yes I think it. But i want to learn what is your approach for this type requirement. I want to find what is the exact way?

Thanks.

Changing your line to a plot is probably the easiest way to go here.

Horizontal lines added via Initialize Add( new line can't be changed dynamically.

Set a plot with a single double value and then assign colors with PlotColors[][] index.

ZeroLine.Set(0);

if (CrossAbove(Plot0, ZeroLine, 1))
PlotColors[1][0] = Color.Red;
