Quote from caementarius:
What do these firms offer exactly? Less stringent margin requirements? I'd be interested to know what some of the deals offered are and what levels of contribution are necessary.
They offer you a membership into a JBO. You trade on risk based haircuts, not Reg T or CPM which is crap. No margin calls, no forced liquidations, borrow trading capital from the JBO, no cancel fees on options, cross margins between futures and cash options, better tax treatment. What else do you want to know?
