Does Bars refer to current Bars object in OnBarUpdate()?

[overflowing]

What does the Bars property/field refer to?

Does it refer to the BarsArray[BarsInProgress] for the current call to OnBarUpdate()? That is, does BarsArray[BarsInProgress] == Bars? Can I substitute one for the other or do they refer to different objects?

Bars represents the data that is being processed by your script:

These are used to find the BarsSinceSession, etc

BarsInProgress refers to the current call on OnBarUpdate related to the series that may be added, where BarsInProgress == 0 is the primary data series, and BarsInProgress == 1 would be an added data series.

...where BarsInProgress == 0 is the primary data series, and BarsInProgress == 1 would be an added data series.

So that's my question, does the Bars property always refer to the primary data series? Or does it refer to the current data series that is being handled by OnBarUpdate()?

The Data Series that is being handled by OnBarUpdate

If you were to check Bars.x in OnBarUpdate, you would get multiple calls for each OBU call.

If you wanted to check for only one OBU call, you would need to check for Bars.x in a BIP filter:

		protected override void OnBarUpdate()
		{
			
			
			// This will be called twice as per each OBU call
			Print("BIP : " + Instrument.FullName + " | Bars  : " + Bars.BarsSinceSession);
		
			// These will be called only when that BIP is called
			if(BarsInProgress == 0)
			{
				Print("BIP 0 : " + Instrument.FullName + " | Bars  : " + Bars.BarsSinceSession);
			}
			
			if(BarsInProgress == 1)
			{
				Print("BIP 1 : " + Instrument.FullName + " | Bars  : " + Bars.BarsSinceSession);
			}
                  }

So from within OnBarUpdate(), BarsArray[BarsInProgress] == Bars, no?

[NinjaTrader_Matthew]

Yes, that would refer to the current data that is being processed in OBU()
