MultiCharts.net EMA Color Slope

March 16th, 2021, 10:12 PM

I couldn't find this indicator online anywhere for MultiCharts.net, so I modified the built-in EMA indicator on MulitCharts.net to change color based on the slope. Posting here in case anyone needs it.

using System;
using System.Drawing;
using PowerLanguage.Function;

namespace PowerLanguage.Indicator
{
[SameAsSymbol(true)]
public class Mov_Avg_Exponential_Color : IndicatorObject
{
private XAverage m_xaverage1;

private VariableSeries<Double> m_avgexp;

private IPlotObject Plot1;

public Mov_Avg_Exponential_Color(object ctx) :
base(ctx){
length = 9;
usecolorupdown = true;
colorup = Color.GreenYellow;
colordown = Color.Red;
}

private ISeries<double> price { get; set; }

[Input]
public int length { get; set; }

[Input]
public int displace { get; set; }

[Input]
public bool usecolorupdown { get; set; }

[Input]
public Color colorup { get; set; }

[Input]
public Color colordown { get; set; }

protected override void Create(){
m_xaverage1 = new XAverage(this);
m_avgexp = new VariableSeries<Double>(this);
Plot1 =
AddPlot(new PlotAttributes("AvgExp", 0, Color.GreenYellow,
Color.Empty, 0, 0, true));
}

protected override void StartCalc(){
price = Bars.Close;
m_xaverage1.Price = price;
m_xaverage1.Length = length;
}

protected override void CalcBar(){
m_avgexp.Value = m_xaverage1[0];
if (((displace >= 0)
|| Bars.CurrentBar > Math.Abs(displace)))
if (usecolorupdown)
{
if (PublicFunctions.DoubleGreater(m_avgexp.Value, m_avgexp[1]))
Plot1.Colors[0] = colorup;
else
Plot1.Colors[0] = colordown;
}{
Plot1.Set(displace, m_avgexp.Value);
if ((displace <= 0)){
if (((PublicFunctions.DoubleGreater(price[0], m_avgexp.Value) &&
PublicFunctions.DoubleGreater(m_avgexp.Value, m_avgexp[1]))
&& PublicFunctions.DoubleLessEquals(m_avgexp[1], m_avgexp[2]))){
Alerts.Alert("Indicator turning up");
}
else{
if (((PublicFunctions.DoubleLess(price[0], m_avgexp.Value) &&
PublicFunctions.DoubleLess(m_avgexp.Value, m_avgexp[1]))
&& PublicFunctions.DoubleGreaterEquals(m_avgexp[1], m_avgexp[2]))){
Alerts.Alert("Indicator turning down");
}
}
}
}
}
}
}
