Syntax


public static void PlotSymbolTrades(this WealthScript obj, Bars symbol, ChartPane pane)

public void PlotSymbolTrades(Bars symbol, ChartPane pane)

Parameter Description

symbol	The Bars object of an external symbol
pane	ChartPane to plot the trades on

Description

Visualizes trades made on external symbols. Helpful for pair trading strategies and in general, for any strategy that makes trades on an external symbol.

Example

Here is an example illustrating how to use the method in your Strategy code. Make sure you have "KO" in one of your DataSets and run the example on another symbol:

Example using C# extension methods:


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

namespace WealthLab.Strategies
{
	public class PlotSymbolTradesDemo : WealthScript
	{	
		protected override void Execute()
		{
			for(int bar = 40; bar < Bars.Count; bar++)
			{
				if (IsLastPositionActive)
				{
					Position p = LastPosition;
					SetContext( "KO", true );
					if( p.PositionType == PositionType.Long )
						SellAtStop( bar+1, p, Lowest.Series( Low,20 )[bar] );
					else
						CoverAtStop( bar+1, p, Highest.Series( High,20 )[bar] );
					RestoreContext();
				}
				else
				{
					SetContext( "KO", true );
					Position p = BuyAtStop( bar+1, Highest.Series( High,40 )[bar] );
					if( p == null )
						ShortAtStop( bar+1, Lowest.Series( Low,40 )[bar] );
					RestoreContext();
				}
			}
			
			const string SymbolPair = "KO";
			if( Bars.Symbol != SymbolPair )
			{
				ChartPane pane = CreatePane( 100, false, true );
				this.PlotSymbolTrades( GetExternalSymbol( SymbolPair, true ), pane );
				HideVolume();
			}
		}
	}
}
