Really? So if I tell them I got 10M, and just deposit 1Ms from accounts in my name (and if I remember correctly, one could even deposit crypto at some point), they won't ask any SOF/SOW questions?
Sorry for the stupid questions, I haven't used IB since the COVID crash, but it might be of use in the future, one never knows. Loved their low margin interest rates (and they were actually the very reason my account got decimated during the crash).
