read over the educational newsletter and previous posts: Typical strong gap up that does not attempt to fill the gap, generally you can tell within 10 - 20 min. I typically just go long as trend days push strongly higher despite the large gap.  I then try to add to that position on shallow dips the first 3hrs. UPRO can be used, and I typically just trade ES or MES these days. Then you get a standard 1 hr consolidation mid day that allows on a 5 min SPX cash for price to recycle back to or close to the 50 SMA, the VWAP, and a fast 10 length Stochastic to get oversold, while a 60 length stochastic remains over 80%. also MACD tends to recycle back near the zero level. Then typically you get another pop to a new mid intra day high in the afternoon. Price will either run until the close or you might get a pullback the last hr from some divergence
