Color the zone between 2 EMA's

[Tobees]

Hello,

I want to color the zone between 2 EMA's on the main chart.
When the fast EMA upcrosses the slow EMA the zone must be colored ForestGreen
When the fast EMA downcrosses the slow EMA the zone must be colored orange.Red

I have written a script, but nothing is plotted.
Can Someone help me out. What am I doing wrong? I already added some Print commands but they never get executed

namespace NinjaTrader.NinjaScript.Indicators
{
public class EMACrossFillZone : Indicator
{
private Series<double> emaFast;
private Series<double> emaSlow;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Custom Indicator to plot zone between two EMAs with customizable settings";
Name = "EMACrossFillZone";
IsOverlay = true;
FastEMA = 20;
SlowEMA = 110;
FastEMACrossColor = Brushes.OrangeRed;
SlowEMACrossColor = Brushes.ForestGreen;
Opacity = 25;
}
else if (State == State.DataLoaded)
{
emaFast = new Series<double>(this);
emaSlow = new Series<double>(this);
}
}

protected override void OnBarUpdate()
{
if (CurrentBar < SlowEMA || CurrentBar < FastEMA)
return;

emaFast[0] = EMA(Close, FastEMA)[0];
emaSlow[0] = EMA(Close, SlowEMA)[0];

if (CrossAbove(emaFast, emaSlow, 1))
{
PlotBrushes[0][0] = FastEMACrossColor;
Print("Fast EMA Crossed Above Slow EMA");
}
else if (CrossBelow(emaFast, emaSlow, 1))
{
PlotBrushes[0][0] = SlowEMACrossColor;
Print("Slow EMA Crossed Above Fast EMA");
}
else
{
PlotBrushes[0][0] = null;
}

// Plotting zone between EMAs
if (emaFast[0] > emaSlow[0])
{
PlotBrushes[1][0] = FastEMACrossColor;
PlotBrushes[2][0] = null;
Print("Zone Color: " + FastEMACrossColor.ToString());
}
else
{
PlotBrushes[1][0] = null;
PlotBrushes[2][0] = SlowEMACrossColor;
Print("Zone Color: " + SlowEMACrossColor.ToString());
}
}

Hello Tobees,

Thanks for your post and welcome to the NinjaTrader Forums!

You are not adding any plots to the indicator script in the code you shared by calling the AddPlot() method.

To add plots to an indicator, you would need to use the AddPlot() method in the script.

After adding plots to the script, you would need to assign values to those plots so that they appear on the chart window.

See the help guide documentation for more information about AddPlot() and sample code.

To color the region between two Series you would use the Draw.Region() method in the script.

See this help guide page for more information about Draw.Region() and sample code: https://ninjatrader.com/support/help...raw_region.htm
