I have troubles with futures using consolidator and indicators.
I don't get any data coming trough OnData and OnBar
Please help!

After changing
self.res_data = Resolution.Minute
OnData started working
OnBar for some reason still doesn't work

Hi Konstantin!
To consolidate futures data you will need to bind to the futures contract's data, not the root future symbol. You would do this in OnSecurityChanges by looking at the AddedSecurities to see the individual future contracts coming into your algorithm.
Currently, QuantConnect does not have support for continuous contracts.

Dear Jared,
What will happen when contract expire?
Will I need to unregister the consolidator?
Best Regards,
Konstantin

Correct. Please see this example algorithm for a demonstration.
