Syntax

DataSeries CrossUnderBar( DataSeries ds1, DataSeries ds2 );

Parameter Description

ds1	First data series
ds2	Second data series

Description

CrossUnderBar(DataSeries1, DataSeries2) returns the most recent bar where DataSeries1 crossed under DataSeries2. No check is made about a possible subsequent CrossOver.

Example

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

using Community.Indicators;

namespace WealthLab.Strategies
{
	public class XUBStrategy : WealthScript
	{
		protected override void Execute()
		{
			BBandUpper bbU = BBandUpper.Series( Close, 20, 2 );
			CrossUnderBar xub = CrossUnderBar.Series( Close, bbU );
			
			SetBarColors( Color.Silver, Color.Silver );
			
			for (int bar = xub.FirstValidValue; bar < Bars.Count; bar++)
			{
				if( xub[bar] == bar ) 
					SetBarColor( bar, Color.Blue );
				
				if (IsLastPositionActive)	
				{          
					SellAtStop( bar+1, LastPosition, Lowest.Series( Low, 20 )[bar] );
				} 
				else
				{
					if( ( Close[bar] < bbU[bar] ) & ( xub[bar] > bar - 3 ) )
						BuyAtMarket( bar+1 );
				}
			}
			
			ChartPane xPane = CreatePane( 20, true, true );
			PlotSeries( xPane, xub, Color.Blue, WealthLab.LineStyle.Dashed, 2 );
			PlotSeries( PricePane, bbU, Color.Blue, WealthLab.LineStyle.Solid, 1 );
		}
	}
