C-how-to-find-the-exit-price-for-a-position

Like superticker said, you can use GetPositions to get the list of all historical positions in the backtest. Or just save the Position instance to a class level variable. Here's a contived example:

CODE:

using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Data;
using WealthLab.Indicators;
using System.Collections.Generic;

namespace WealthScript2 
{
    public class MyStrategy : UserStrategyBase
    {
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
        }

        //execute the strategy rules here, this is executed once for each bar in the backtest history
        public override void Execute(BarHistory bars, int idx)
        {
         if (idx == bars.Count - 20)
            PlaceTrade(bars, TransactionType.Buy, OrderType.Market, 0);
         else if (idx == bars.Count - 10)
            PlaceTrade(bars, TransactionType.Sell, OrderType.Market, 0);
         else if (idx == bars.Count - 1)
         {
            List<Position> lst = GetPositions();
            if (lst.Count > 0)
            {
               double exit = lst[lst.Count - 1].ExitPrice;
               string s = "Last Position had an exit price of " + exit.ToString("N2");
               DrawHeaderText(s, WLColor.Cyan, 24);
            }
         }
        }

        //declare private variables below

    }
}
