Syntax

DataSeries CrossOverBar( DataSeries ds1, DataSeries ds2 );

Parameter Description

ds1	First data series
ds2	Second data series

Description

CrossOverBar(DataSeries1, DataSeries2) returns the most recent bar where DataSeries1 crossed over DataSeries2. No check is made about a possible subsequent CrossUnder.

Example

This example illustrates how to plot and call the CrossOverBar series. The entry is made when Close has crossed over the Lower Bollinger Band within last 3 bars, and it is still currently over the same band:


using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;
using Community.Indicators;

namespace WealthLab.Strategies
{
	public class XOBStrategy : WealthScript
	{
		protected override void Execute()
		{
			BBandLower bbL = BBandLower.Series( Close, 20, 2 );
			CrossOverBar xob = CrossOverBar.Series( Close, bbL );
			
			SetBarColors( Color.Silver, Color.Silver );
			
			for (int bar = xob.FirstValidValue; bar < Bars.Count; bar++)
			{
				if( xob[bar] == bar ) 
					SetBarColor( bar, Color.Red );
				
				if (IsLastPositionActive)	
				{          
					CoverAtStop( bar+1, LastPosition, Highest.Series( High, 20 )[bar] );
				} 
				else
				{
					if( ( Close[bar] < bbL[bar] ) & ( xob[bar] > bar - 3 ) )
						ShortAtMarket( bar+1 );
				}
			}
			
			ChartPane xPane = CreatePane( 20, true, true );
			PlotSeries( xPane, xob, Color.Red, WealthLab.LineStyle.Dashed, 2 );
			PlotSeries( PricePane, bbL, Color.Red, WealthLab.LineStyle.Solid, 1 );
		}
	}
