I have always wondered how MM these days make $$ given the sheer number of options exchanges alone (16?) in equities. I have a MM friend at IB and he tells me they get picked off enough which surprised me bec I always thought that Ib had a good enough technology against that. A question I've always pondered ever since I left the floor in the NYBOT was --who makes markets in the futures space nowadays. I would think the $$ is still there since there is very little competition vs. equities with its 16 exchanges. Like CL , KC, SB , OJ options. Who are the participants? In the 1990-2005(?) a guy can put up 100k in a futures acct like Gelderman, Refco in return for a guarantee to the exchange, lease a seat for $300-$1000/mo, get 25 cents per side, scalp all day and put on enough positions to make it worth it. How is it done now? I would think 100k is now a pittance to start?
