Change color on a EMA up and Down

[perryg]

I am trying a very simple strategy to change color when going up and down. I get error message "double" doesn not contain a definition for Plots. The following is the code

if (Rising(EMA(15)))
EMA(15)[0].Plots[0].Pen.Color = Color.Aqua;



// Condition set 2
if (Falling(EMA(15)))

EMA(15)[0].Plots[0].Pen.Color = Color.Orange;

}

perryg, welcome to the forums! I suggest you follow this sample here and modify the code presented to use an EMA as base - http://www.ninjatrader-support2.com/...ead.php?t=3227

Much obliged. It works perfectly
