Prime brokerage is based on "need", not cost. You need a service your Prime does not offer.Fair enough. It's $1m at IB but they will charge you $1000 per month that can be netted off against commissions. So if you generate 1000 in commissions, you won't pay anything.
I personally think that you need 5m+ (as you say) to make the best out of it.
