Syntax


public static bool ExitAtPrice(this WealthScript obj, Bars bars, int bar, Position p, double price, string signalName)

public bool ExitAtPrice(Bars bars, int bar, Position p, double price, string signalName)

Parameter Description

Bars	Bars object
bar	Bar number on which the position is being created
p	Position to close
price	Exit price
signalName	Signal name

Description

This function, created by Dion Kurczek, allows you to exit a Position at any specific price within the bar's range. It will trigger an alert correctly, although the alert will be displayed as a limit order for the price specified. The function returns true if the Position was closed. A key component in Wealth-Lab support for importing real (historical) trades.

Note: The function can't be used to enter trades outside of the bar's range.

Example

Below is a demo Strategy that shows how to use the function.

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 AtPriceDemo : WealthScript
	{
		protected override void Execute()
		{	
			// initialize your average series however you like		
			DataSeries avgSer = 0.5 * Open + 0.5 * Close;
			
			/* In the trading loop here's the buy signal that uses your peeking data.  
			   It won't create an Alert because they're peeking results.  Not a tradeable script! */
			for(int bar = 1; bar < Bars.Count; bar++)
			{
				if (IsLastPositionActive)
				{
					if( true )	// some condition to exit at the average price this month 
						this.ExitAtPrice(Bars, bar, LastPosition, avgSer[bar], "Out");
				}
				else
				{
					if( true )	// some condition to buy at the average price this month 
						this.EnterAtPrice(Bars, bar, avgSer[bar], PositionType.Long, "In");
				}
			}
			
		}
	}
}
