Pyramiding-position-sizer-Reverse-Incremental-and-same-bar-multiple-positions

Summary of issue: The Advanced Position Sizer/ Pyramiding/ Reverse Incremental sizer is not incrementing position size correctly when there is more than one position to be opened on a bar.

Test code:

CODE:
using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Indicators;
using System.Collections.Generic;

namespace WealthScript13 
{
    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 (OpenPositions.Count < 5)
         {
            if (OpenPositions.Count == 0)   //there's no open Position
            {
               if (idx == bars.Count - 20)
               {
                  PlaceTrade(bars, TransactionType.Buy, OrderType.Market, 0, "P1, Initial Position");
                  WriteToDebugLog(bars.DateTimes[idx].ToShortDateString() + "\t" + "OpenPositionCt =" + "\t" + OpenPositions.Count);
               }
            }
            else
            {
               int n = 4;
               for (int j = 0; j < n; j++)
               {
                  PlaceTrade(bars, TransactionType.Buy, OrderType.Market);
                  WriteToDebugLog(bars.DateTimes[idx].ToShortDateString() + "\t" + "OpenPositionCt =" + "\t" + OpenPositions.Count);
               }
            }
         }
        }

        //declare private variables below

    }
}

Details of Positions created:



Debug log to show what Position count the sizer is using:



Observations:
- Position size of 1st Position is correct
- Position size of 2nd Position (taken on another bar) is also correct - it gets incremented by 50% as per settings
- Position size of all subsequent Positions on that bar should have been incremented by 50% over previous position's but is not; this is happening because the Position sizer is not updating the Position count as it should after opening each new position

Note: I *only* checked the Reverse Incremental Pyramiding Position Sizer, can't comment on any other sizer that may also be using Position count for its calculations.
