Today I tested my strategy, that works fine with a single account, with an IB multiaccount. I sent the entry orders from the master advisor account and when entering the market it was OK. It took the same position quantity from each IB subaccount.
When exiting it made a big mess. It seems that it doesn't really know if a part of the position belongs to a subaccount or another. It started changing the position sense without any criteria.
I'm only connnected to IB. No other broker.
Do you know how to solve it?
