Volumetric array out of bounds

[tonystarks]

For some reason, I started getting an array out of bounds. It looks like the last bar was 1716, but it is trying to look for 1717. This was previously working without any issue and then I started noticing this recently. My expectation is to get the current delta of the current volumetric bar.

NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType barsType = Bars.BarsSeries.BarsType as
              NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType;

      if (barsType != null)
      {
        currentDelta = barsType.Volumes[CurrentBars[VOLUMETRIC_BAR]].BarDelta; // Errors here. VOLUMETRIC_BAR is 1, which is what I currently have in the State.Configure
      }​

I found my issue. I updated my visual chart to a Range 15, but still had AddVolumetric in the State.Configure section to Range 10.

Hello tonystarks,

It sounds like you need a proper current bars check.

private NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType volumetricBars;
private double currentDelta;

else if (State == State.Configure)
{
    AddVolumetric(null, BarsPeriodType.Minute, 1, VolumetricDeltaType.BidAsk, 1);
}
else if (State == State.DataLoaded)
{
    if (BarsArray.Count() > 0)
        volumetricBars = BarsArray[1].BarsSeries.BarsType as NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType;
}​

if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 1 || CurrentBars[1] < 1)
return;

if (volumetricBars != null)
{
    currentDelta = volumetricBars.Volumes[CurrentBars[1]].BarDelta;
    Print(string.Format("{0} | currentDelta: {1}", Times[1][0], currentDelta));
