Change color on custom indicator

[pakricard]

Hi:;

I'm developing a custom indicator, an EMA.

I want it to change color depending of the slope of the EMA
So, on Initialize I have:
Add(new Plot(Color.FromKnownColor(KnownColor.Transparent), PlotStyle.Line, "MyMA"));


And OnBarUpdate()

if (MyMA[0] > (MyMA[1] )
{
MyMA[0].Color = Color.Green;
}else if (MyMA[0] < (MyMA[1] )
{
MyMA[0].Color = new Color(Color.Red);
}else
{
MyMA[0].Color = new Color(Color.Ivory);
}

being MyMA the Plot draw by the indicator.

Well, it does not work :-(

What shouyld I code?

Thanks

pakricard, I would suggest reworking this code to use the NT7 PlotColors method to achieve the desired outcomes - http://www.ninjatrader.com/support/h...plotcolors.htm
