Collective2 supports trading of options on equities and ETFs, but not options on futures. If your trading strategy involves trading of options on a major index, such as the S&P500, or the Dow Jones Industrials, consider using options on the relevant ETF instead. For example, if your system needs to trade options on the S&P500, you can use use options on the SPY (the "Spider," an ETF traded on AMEX). For Dow Jones Industrial Average, you can use DIA (the "Diamond" ETF).
Also, we do support all CME currency futures contracts which include 6A, 6B, 6C, 6E, and 6J among others. For example - the GBP (the Pound) is the 6B futures contract. You could trade that, just not the option.
