I know there are a lot of ET traders trading the S&P futures, but do many traders bother trading the OEX or SPX options? And how about the weeklys? Any use for them? I only ask as I consider myself a student of options and wonder if there is any advantage to trading the index options instead of the SPY (ETF) options. Would the OEX weekly be a good vehicle to use for a straddle on the FOMC week? Thanks in advance for the help and the flames.
