Momentum change for the S&P Index?

I just caught this situation on the 1 hour charts. Nice divergence formation and a very large bearish engulfing bar signaling a possible break downwards. If that bar breaks its lows it will confirm a shift from bullish to bearish momentum.

Bellow I have included a zoomed out chart to point out a key price area. I have marked a prize pivot in orange color. That zone has been visited for the first time since the end of August. The location of the bar is very good and has a solid backing from that resistance pivot. So here we have area, we have a nice bar formation and divergence indicating a weakening of the bull momentum. Let see if the downward momentum materializes.
