CrossOverBar: Indicator Documentation


DataSeries CrossOverBar( DataSeries ds1, DataSeries ds2 );

Parameter Description

ds1 First data series
ds2 Second data series


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


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:

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 ); } } }
