Bar formation different when using IB vs. using SIM

[psycho760]

Hi
I have a strategy I tested using the simulator that trades based on the first 5 minute bar of the day. It uses the open price and the high and low of the first 5 minute bar of the day. It works fine when using the simulated feed and account.

However when I connect to my IB account, the same code sends out trades as soon as it gets an open price. Why is there this difference in sim vs IB?
Here is the code that detects bars

                if (BarsInProgress == 1)
                {
                    if (!Period1Elapsed)
                    {
                        if (CurrentBar > 0)
                        {
                                                    Print(String.Format("Opening " + period1 
                                  + "Bar  Hi:{0} Lo:{1}", Highs[1][Bars.BarsSinceSession],
                                                    Lows[1][Bars.BarsSinceSession]) + "Bars since session " + Bars.BarsSinceSession);
                            Period1HighPrice = Highs[1][Bars.BarsSinceSession];
                            Period1LowPrice = Lows[1][Bars.BarsSinceSession];
                            if (Period1HighPrice != 0 && Period1LowPrice != double.MaxValue)
                            {
                                Period1Elapsed = true;
 
                                if(true)
                                {
                                    HI = Period1HighPrice;
                                    LO = Period1LowPrice;
                                    STOP_PRICE = Period1LowPrice;
                                    Print(String.Format("{0} will use period 1 prices HI:{1} LO:{2}",
                                        Instrument.FullName.PadRight(5, ' '), Period1HighPrice, Period1LowPrice));
                                    //send trades if this is real time
                                    if (!Historical)
                                    {
                                          //SEND OUT BUY TRADE
                                    }
                                }
                            }
                        }
                    }
                }

Additionaly I am using minute bars - days to load =1 and the BarsInProgresss=1 should mean 5 minute bars because this is what I do on initialize

protected override void Initialize()
{
currentDate = DateTime.Now.Date;
EntriesPerDirection = 2;
Add(PeriodType.Minute, 5);
Add(PeriodType.Minute, 15);
CalculateOnBarClose = false;

}

Hi psycho760,

We're not aware of a an issue where NinjaTrader processes signals differently on a simulated feed compared to Interactive Brokers feed. If the conditions are true, then it processes the code block that follows, and it does this regardless of the feed.

You're printing all values. Are they not calculating as you expect?
