2 color EMA missing some segments !

[afshinmoshrefi]

I am working on a 2 color EMA which changes color based on the intensity of the trend. When I run the indicator, the first segment that color changes is missing and does not draw; I cannot figure out why!!

I am testing this EMA on CL - 6 Range bars.

can't imagine this be a Ninja bug. Any insight would be greatly appreciated.

This is the indicator code:

protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Gold), PlotStyle.Line, "Plot0"));
Add(new Plot(Color.FromKnownColor(KnownColor.Black), PlotStyle.Line, "Plot1"));
Overlay = true;
}

protected override void OnBarUpdate()
{

if (CurrentBar<13)return;
double tValue = EMA(Close, 13)[0] - EMA(Close, 13)[3];

if (tValue > 0.025 || tValue < -0.025)
Plot0.Set(EMA(Close,13)[0]);
else
Plot1.Set(EMA(Close,13)[0]);
}

Hello afshinmoshrefi,
The values are there, however it is the way NinjaTrader draws the plot values and thus you are witnessing the scenario.

For coloring the Plot values we suggest using only one Plot series and use the PlotColors method to color the Plot.

Please refer to our help guide to know more about PlotColors

A sample code will be like

if (CurrentBar<13)return;
double tValue = EMA(Close, 13)[0] - EMA(Close, 13)[3];

Plot0.Set(EMA(Close,13)[0]);
			
if (tValue > 0.025 || tValue < -0.025)
	PlotColors[0][0] = Color.Green;	
else
	PlotColors[0][0] = Color.Red;
