Whew....based on history, you should just check out in the morning and not do anything at all. There is some hobble of price action, but historically the swings are very small, with low opportunity for scalping. Flat, and all within range all day until the Fed Announcement. Which way will the market go at announcement? Who knows. Wait for an initial huge swing at the announcement and then a reversal at 230. The 230 reversal is usually the correct move.
