Hey all, I've worked at the CBOT, CME, and NYMEX during college and currently trade STIR products for an institution but I've always wanted to learn how MMs trade in the options pit. I have a decent understanding of options but I'm curious how these guys make their money. Are they simply reading off the tablet or sheets and making a bid/offer and then delta hedging as the mkt moves? If they are always delta heding what happens if they get a hit for a 100 lot and the futures are only 10x10? I'd appreciate any insight. I'm specifically interested in what the guys trading corn, soybeans, bonds, eurodollars, and S&Ps are doing if anyone has worked in those option pits.
