TRIX

Modified on 2008/05/03 16:05 by Administrator — Categorized as: Standard Indicators

Syntax

public static TRIX Series(DataSeries source, int period)
public TRIX(DataSeries source, int period, string description)

Parameter Description

source	The source DataSeries
period	Indicator calculation period

Description

TRIX displays the percentage Rate of Change, ROC, of a triple exponentially-smoothed moving average, EMA, over the specified Period. TRIX oscillates above and below the zero value. The indicator applies triple smoothing in an attempt to eliminate insignificant price movements within the trend that you're trying to isolate.

Interpretation

TRIX generates a signal when it changes direction (turns up or down). Alternately, you can create a signal line using a moving average and wait until TRIX crosses this signal line.

using WealthLab;
using WealthLab.Indicators;

namespace WealthLab.Strategies
{
	public class MyStrategy : WealthScript
	{
		protected override void Execute()
		{
			/* Buy when TRIX turns up from below zero.  
			Sell when TRIX crosses above zero. */

			int Per = 24;
			DataSeries trix = TRIX.Series( Close, Per );
			ChartPane TRIXPane = CreatePane( 25, true, true );
			PlotSeries( TRIXPane, trix, Color.Brown, WealthLab.LineStyle.Solid, 2 );
			
			for(int bar = 60; bar < Bars.Count; bar++)
			{
				if (!IsLastPositionActive)
				{
					if( TurnUp( bar, trix ) && ( trix[bar] < 0 ) )
						BuyAtMarket( bar+1 );
				}
				else
				{
					if( CrossOver( bar, trix, 0 ) )
						SellAtMarket( bar+1, LastPosition );
				}
			}
