Does anyone understand the options difference between these two? If I go to trade the /es futures for the end of October, I can sell 2 and get a credit equal to the amount of selling the same strike in SPX if I sell just 1. The difference is, SPX will take up about 45,000 of my account. Whereas the /es will only take about $9,000.00. What am I missing here? I can't see how this could possibly be right. Anyone get what I'm saying and know what I'm missing?
