CrossUnderValueBar: Indicator Documentation

Syntax

DataSeries CrossUnderValueBar( DataSeries ds, double value );

Parameter Description

ds	Data series
value	Some value

Description

CrossUnderValueBar(DataSeries, double) returns the most recent bar where DataSeries crossed under Value. No check is made about a possible subsequent CrossOver.

Example

This example illustrates how to plot and call the CrossUnderValueBar series. The entry is made when CCI(Bars, 14) has crossed under value 100 within last 3 bars, and it is still currently under 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 XUVBStrategy : WealthScript
	{
		protected override void Execute()
		{
			CCI cci = CCI.Series( Bars, 14 );
			int val = 100;
			CrossUnderValueBar xub = CrossUnderValueBar.Series( cci, val );
				
			SetBarColors( Color.Silver, Color.Silver );
			
			for (int bar = xub.FirstValidValue; bar < Bars.Count; bar++)
			{
				if( xubbar == bar ) 
					SetBarColor( bar, Color.Red );
				
				if (IsLastPositionActive)	
				{          
					SellAtStop( bar+1, LastPosition, Lowest.Series( Low, 20 )bar );
				} 
				else
				{
					if( ( ccibar < val ) & ( xubbar > bar - 3 ) )
						BuyAtMarket( bar+1 );
				}
			}
			
			ChartPane xPane = CreatePane( 20, true, true );
			ChartPane cciPane = CreatePane( 20, true, true );
			PlotSeries( xPane, xub, Color.Blue, WealthLab.LineStyle.Dashed, 2 );
			PlotSeries( cciPane, cci, Color.Blue, WealthLab.LineStyle.Solid, 1 );
			DrawHorzLine( cciPane, val, Color.Black, WealthLab.LineStyle.Dashed, 1 );
		}
	}
