Different-bar-start-dates-on-two-PCs

Data providers across the machines may be different i.e. you may be getting the bars from different providers. See their order and enabled state (checkbox) in the Data Manager.

I will check that in the morning. Thanks!

I tried using my existing setup on my trading laptop (latest WL8, Win 10 Pro). I changed the Historical Provider to TDAmeritrade only. It still wasn't giving the correct TQQQ 5-minute data starting at 9:30AM. It always shows data from 9:35AM and on. So, I decided to reset my trading laptop. I told Windows to keep the files but had it delete the apps and settings. After Win 10 Pro was reset, I reinstalled the latest WL8, TDAmeritrade and CandleSticks. I've selected TD Ameritrade as my historical provider and set the consumer key. I've pasted the code and the partial results of the debug log. It still does the same thing. Why don't I get the data starting at 9:30AM? Am I missing something?

CODE:

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

namespace WealthScript1 
{
    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)
        {
         WriteToDebugLog("date/time = " + bars.DateTimes[idx].ToShortDateTimeString() + "    " +
            bars.Open[idx].ToString() + "    " +
            bars.High[idx].ToString() + "    " +
            bars.Low[idx].ToString() + "    " +
            bars.Close[idx].ToString() + "    " +
            bars.Volume[idx].ToString() + "    ");

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

        //declare private variables below

    }
}

9:35am is correct because by WL's convention, bars are timestamped end-of-bar. (WL even has a special option to convert start-of-bar data in the ASCII provider for that matter.) I'm not an expert in TDA by any means, just make sure your Markets are exactly the same on both PCs.

In general, to guarantee equality I'd recommend physically sync data between the PCs by copying it from one to another. Same for Wealth-Lab's configuration files where you might've applied custom tweaks to the Markets/Symbols on one PC.

Eugene and Cone: Thanks for your help! I was able to fix the problem on my trading laptop. Both machines now match!! Cheers!
