Quote from bwolinsky:
In my ADV even as an IA I'm required to report my relationship with them as a "data publisher", and that's how it is to be treated for him like myself.
There is no AUM under this arrangement. IB requires more than $10,000 to have a margin account.
I trade everyday.
Well, it's not even about that. How much does he manage, own or others' money - not important. You trade every day yet you've never encountered shorting restrictions/unable to borrow...right. It's not about liquidity either, liquid stocks often can't be borrowed, it's not rare.
