I've traded futures for a while, but am not a big enough fish to know the following (perhaps I've been trading with blinders on, which can help on occasion): Do individuals (I'm not talking institutions or professional fund managers) trade the S&P Big Futures online? For anyone with information on this, how does it compare to the S&P E-mini in terms of volume and ability to locate shares? At this point, I'm only asking out of curiosity. It did, however, occur to me that paying commissions on 1 contract (of the Bigs) compared to 5 contracts (of the E-minis) would result in the same profit/loss but with fewer commissions fees in total. I appreciate your help on this one! Best, flapjack
