Syntax


public static void DrawLinRegChannel(this WealthScript obj, int bar, DataSeries ds, int period, double width, Color color, LineStyle style, int line)
public static void DrawLinRegChannel(this WealthScript obj, int bar, DataSeries series, int period, Color color, LineStyle style, int line)
public static void DrawLinRegChannel(this WealthScript obj, int bar, DataSeries series, int period, double width, Color color, LineStyle style, int line, StdDevCalculation sdCalc)

public void DrawLinRegChannel( WealthScript obj, int bar, DataSeries ds, int period, double width, Color color, LineStyle style, int line)
public void DrawLinRegChannel(int bar, DataSeries series, int period, Color color, LineStyle style, int line)
public void DrawLinRegChannel(int bar, DataSeries series, int period, double width, Color color, LineStyle style, int line, StdDevCalculation sdCalc)

Parameter Description

bar	Ending bar
ds	Source data series
period	Lookback period
width	Channel line width
color	Channel line color (System.Color)
style	Channel line style (WealthLab.LineStyle)
sdCalc	Select between the standard deviation of a sample and that of an entire population

Description

Allows to code a linear regression slope channel. Credit for this method goes to Giorgio Beltrame.

Two overloads added by Robert Sucher: the first replicates the Manual Drawing tool for Regression Channel if Close is used as series, the second defines Channel width by Standard Deviations instead of Standard Error.

Look at an example below:

Example

Example using C# extension methods:


using System;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;

public class LinRegChannelsDemo: WealthScript
{
	protected override void Execute()
	{
		Color col = new Color();
		for(int bar = Bars.Count-100; bar < Bars.Count; bar++)
		{
			if( Close[bar] > Close[bar-50] )
				col = Color.Green; else col = Color.Red;
			
			this.DrawLinRegChannel( bar, AveragePrice.Series(Bars), 45, 2, Color.FromArgb(30, col), LineStyle.Solid, 1 );
		}
	}
}

Legacy syntax example:


using System;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;
using Community.Components; // DrawLinRegChannel here

public class LinRegChannelsDemo: WealthScript
{
	protected override void Execute()
	{
		Calculate calc = new Calculate(this); // pass WealthScript as "this"
		Color col = new Color();
		for(int bar = Bars.Count-100; bar < Bars.Count; bar++)
		{
			if( Close[bar] > Close[bar-50] )
				col = Color.Green; else col = Color.Red;
			
			calc.DrawLinRegChannel( bar, AveragePrice.Series(Bars), 45, 2, Color.FromArgb(30, col), LineStyle.Solid, 1 );
		}
	}
}
