I suppose there's a niche for full-service brokers who still get a few percent commission on each trade, but they're falling by the wayside as people go to 1.5%/yr money managers at MEL etc.
In 2005 I got a cold call from a commodities broker who wanted to make money for me trading oil. $100/contract each way, account minimum $5000. I presume he was trading QM, and doing the math it meant a 1% move in the correct direction would mean $100 for me and $200 for him.
