I'm looking for suggested products and underlyings to trade options on commodity and currency futures. My broker is IB, and so if possible I would like to stay with them and use options that are listed on US exchanges. I want to allocate a couple MM to each underlying and so I want to trade things which are more liquid, decent spreads and good execution. Staying with futures for 1256 treatment. The goal is to get a well diversified portfolio. Mostly trading fronts and mid months. Currently thinking of WTI/Oil NatGas EuroDollar EUR/USA GBP/USA CAD/USA AUD/USA Wheat Corn Coffee Any other suggestions, underlying(s) that people would suggest? Feedback regarding execution, market depth, and experiences most welcome. Thanks!
