Access-MetaStrategy-from-a-child-Strategy

I need to calculate used capital (positions cumulative value) of a MetaStrategy on a daily basis.

For this I created a mock strategy and included it into the MetaStrategy. I can access CurrentEquity of the MetaStrategy, but I need MetaStrategy.Positions to calculate current leverage. But I don't understand how to access the MetaStrategy object from the UserBaseStrategy. I found IsMetaStrategyComponent field, so there should be some connection between Meta and regular strategies... or not?

Can you please suggest, how I can access the MetaStrategy object?

Thank you
