Add Volumetric to Strategy

[ttrader23]

When I try to use Volumetric as a secondary series I get an error.
I am trying to add it using the following in state.configure.

AddVolumetric(BarsArray[0].Instrument.FullName,BarsArray[0].BarsPeriod.BaseBarsPeriodType,1, VolumetricDeltaType.BidAsk, 1);

Hello ttrader23,

The error you are getting means an object was null. I see you are trying to use variables for the AddVolumetric which is not supported, you need to type in the values as shown in the help guide sample:

AddVolumetric("ES 03-18", BarsPeriodType.Minute, 1, VolumetricDeltaType.BidAsk, 1);
