looking on IB I found 5 gold futures contracts (us-based) not sure if there are more? ZG nyseliffe full size 8Q nymex emini 1/3 MGC nymex emicro 1/10 QO nymex miny 1/2 GC nymex full size so the full sized GC is obvious but what bout the others? why does nymex have so many? which is the preferred mini to trade? I typically trade CL and QM (mini CL) and was looking for the same in gold. Thanks B
GC is it. For all the others volume is low and consequently the spread is painfully wide, like an overzealous gynecologist cranking a speculum wide. If your horizon is wider than a contract's duration, you might look at the ETF GLD. Spread is usually a penny.
