Quote from wonderworld:
How? I looked into it and every broker says it is impossible. They said you can't buy the emini S&P 500 between the .25 spread. They said you can only buy it at .25 of bid or ask. Is there something I don't know? Or a way to trade between the bid ask of emini?
They buy the big contract and sell the mini contract. One big = 5 mini's. The big contract trades in tenths, the mini in quarters creating some good opportunites for the locals in the pit. Get some new brokers if they can't understand or don't know about the arbitrage that goes on between the big contract and the mini.
