AddDataSeries missing data?

[swcooke]

I am trying to understand processing multiple bars arrays and I am reading the help guide section on that topic. I've built a simple example script to demonstrate an issue I am having. In my case, I am adding an additional 1 minute bars object and each time OnBarUpdate processes this additional bars array, I am adding a 1 count to a plot. I am expecting that the plot will show me 390 updates per day but it is very inconsistent which makes me think I am not understanding something. Here is the code as well as a short video to show my results:

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                                    = @"Enter the description for your new custom Indicator here.";
                Name                                        = "sjTestXLB";
                Calculate                                    = Calculate.OnBarClose;
                IsOverlay                                    = false;
                DisplayInDataBox                            = true;
                DrawOnPricePanel                            = true;
                DrawHorizontalGridLines                        = true;
                DrawVerticalGridLines                        = true;
                PaintPriceMarkers                            = true;
                BarsRequiredToPlot                            = 0;
                ScaleJustification                            = NinjaTrader.Gui.Chart.ScaleJustification.Right;
                IsSuspendedWhileInactive                    = true;
                AddPlot(new Stroke(Brushes.RoyalBlue, 2), PlotStyle.Bar, "TestVal");
            }
            else if (State == State.Configure)
            {
                AddDataSeries("XLB", Data.BarsPeriodType.Minute, 1, Data.MarketDataType.Last);
            }
        }

        protected override void OnBarUpdate()
        {
            if (CurrentBars[0] < 0) return;

            if(BarsInProgress == 1){
                TestVal[0] += 1;
            };
        }

Here is a quick video demonstrating by results:

Hello swcooke,

Thank you for your note.

This looks like a data issue, possibly to do with bar caching - I'm seeing it return 390 every day on my end. Let's have you delete your cache and test again.

To delete the cache, follow the steps below.

• Shut down NinjaTrader.
• Open the Documents > NinjaTrader 8 > db folder.
• Delete the sub-folder named 'cache'.
• Restart NinjaTrader and test.

Please let us know if we may be of further assistance.
