Bars.GetBars() doesnt work on multiple dataseries

[kezyclaire]

Hi,

I have a syntax below for me to get the Bars Ago using Time, I have multiple dataseries in the program. I am getting negative value for the barsAgo. How do I fix this?

DateTime convertedTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 8, 30, 00);
int barsAgo = Bars.GetBars(convertedTime);



Additionally, getting BarNumber using below code works in 5 Minute Chart but not in my 1 Minute chart so I was trying above code. I am also getting negative value.

clickPoint.X = ChartingExtensions.ConvertToHorizontalPixels(e.Get Position(ChartControl as IInputElement).X, ChartControl.PresentationSource);
clickPoint.Y = ChartingExtensions.ConvertToVerticalPixels(e.GetPo sition(ChartControl as IInputElement).Y, ChartControl.PresentationSource);
barsAgo = CurrentBars[0] - (int)ChartControl.GetSlotIndexByX((int)clickPoint. X);

Thanks

Hello kezyclaire,

You will need to specify the bars you want to get a bar from.

BarsArray[1].GetBar(convertedTime) would get the bars from the added series.

Hi Chelsea,

Now that works, thanks!

Hi Chelsea,

I have an additional data series and want to calculate the barnumber of a specific date and time of the primary data stream on the chart.

I tried the following code, but unfortunately, it does not seem to work based on your example above. Can you please advise?

    public class DateToBarNumber : Indicator
    {
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                                    = @"Enter the description for your new custom Indicator here.";
                Name                                        = "DateToBarNumber";
                Calculate                                    = Calculate.OnBarClose;
                IsOverlay                                    = false;
                DisplayInDataBox                            = true;
                DrawOnPricePanel                            = true;
                DrawHorizontalGridLines                        = true;
                DrawVerticalGridLines                        = true;
                PaintPriceMarkers                            = true;
                ScaleJustification                            = NinjaTrader.Gui.Chart.ScaleJustification.Right;
                //Disable this property if your indicator requires custom values that cumulate with each new market data event.
                //See Help Guide for additional information.
                IsSuspendedWhileInactive                    = true;
            }
            else if (State == State.Configure)
            {
                AddDataSeries(BarsPeriodType.Minute, 60);    
            }
        }

        protected int DatumToBarNumber(DateTime BarDateTGime)
        {
            int BarNumberOfDateTime=BarsArray[0].GetBars(Time[0]);
            return BarNumberOfDateTime;
        }
        protected override void OnBarUpdate()
        {
            //Add your custom indicator logic here.
            if (BarsInProgress==1)
            {
                int BarNummer=DatumToBarNumber(Time[0]);
            }
        }
    }​

Hello Gerik,

BarsArray[0] is the primary bar.

If you want the 60 minute series use BarsArray[1].

[Gerik]

Hello Chelsea,

unfortunately,

int BarNumberOfDateTime=BarsArray[0].GetBars(Time[0]);

does not compile. Why?

Kind regards
Gerik

Hello Gerik,

Apologies, that should be BarsArray[0].GetBar(Time[0]).
(Not plural)

[Gerik]

Thank you Chelsea. That works now!
