Error when retrieving instrument type

[guillembm]

Hello,

Iam getting the error "Error on calling 'OnStateChange' method: Object reference not set to an instance of an object." with this line of code.

if (PositionsAccount[0].Instrument.MasterInstrument.InstrumentType == InstrumentType.Forex)

Is this syntax correct?

Thanks

Hello guillembm,
Thanks for your post.

PositionsAccount will not be accessible inside most of OnStateChange(). If you would like this logic to be inside OnStateChange() you will want to put it inside State.RealTime. Otherwise, you can put it inside OnBarUpdate().
