CrossOverValueBar: Indicator Documentation

Syntax

DataSeries CrossOverValueBar( DataSeries ds, double value );

Parameter Description

ds	Data series
value	Some value

Description

CrossOverValueBar(DataSeries, double) returns the most recent bar where DataSeries crossed over Value. No check is made about a possible subsequent CrossUnder.

Example

This example illustrates how to plot and call the CrossOverValueBar series. The entry is made when CCI(Bars, 14) has crossed over value -100 within last 3 bars, and it is still currently over value -100:


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 XOVBStrategy : WealthScript
	{
		protected override void Execute()
		{
			CCI cci = CCI.Series( Bars, 14 );
			int val = -100;
			CrossOverValueBar xob = CrossOverValueBar.Series( cci, val );
				
			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( ( cci[bar] > -val ) & ( xob[bar] > bar - 3 ) )
						ShortAtMarket( bar+1 );
				}
			}
			
			ChartPane xPane = CreatePane( 20, true, true );
			ChartPane cciPane = CreatePane( 20, true, true );
			PlotSeries( xPane, xob, Color.Red, WealthLab.LineStyle.Dashed, 2 );
			PlotSeries( cciPane, cci, Color.Blue, WealthLab.LineStyle.Solid, 1 );
			DrawHorzLine( cciPane, val, Color.Black, WealthLab.LineStyle.Dashed, 1 );
		}
	}
