This may sound like a no brainer, but I need someone to do a sanity check on me. If I need low clearing costs to run a trade profitably with high volume, but I need high volume to get low clearing costs, what's the solution? Do clearing firms ever let people ramp up their volume trying to hit a target price with a trial rate while I ramp up volume, or do I have no option but to find a partner that already has very low clearing rates?
