S&P 500 (futures): Bulls hold the upper hand for now

The key levels intra-day and from a swing trading basis are clear: 3758 (GREEN) & 3730 (ORANGE). Until proven otherwise, I'm leaning towards re-establishing longs. The failure at 3800 early in the session was a good heads up to stand aside. right now, neither bulls or bears can offer a catalyst. Until I see internals and options volume leans bullish, I'm on the sidelines.
