Test code:

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

namespace WealthScript9 
{
    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)
        {
         ind1 = new FractalDown(bars.Low,2);
         PlotIndicator(ind1, WLColor.FromArgb(255,255,0,255), PlotStyle.Dots);
        }

        //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 (!HasOpenPosition(bars, PositionType.Long))
            {
                //code your buy conditions here
            }
            else
            {
                //code your sell conditions here
            }
        }

        //declare private variables below

      private IndicatorBase ind1;
    }
}

Check it out on a recent IPO such as BIRK... there'll be an "index was out of range" exception.
I didn't check related indicators such as FractalUp, FractalUp(Down)Bar.
It would be nice if the developers can modify the code so that such situations are handled more gracefully.
