Any recommendations as to the best broker for pit traded grains? I'm looking to trade 1-5 lots in Beans, Corn, Wheat futures and options. I'd also want to be able to put in orders during the overnight ECBOT sessions. I'm currently using IB to trade various index futures and options, but it appears they won't be offering any pit traded contracts in the near future. Obviously, low commissions and slippage are key, but I'd also prefer a simple web-based order entry system. Any suggestions/input appreciated!
