In the last 5 FOMC, the 2pm candle was either red or doji/choppy (yellow) AND the 2:30 candle was GREEN. So sell 2pm, buy 2:30pm is the pattern. In a few instances it retraced the 2:30 move shortly after, tho, so be nimble not greedy.
Looking at these partitions you see some interesting fractal patterns, too. Could this be another setup for a check down? If not, maybe an inverted check up? Maybe since the orange bottoming pattern is compressed, the next pattern is compressed as well? I'll be looking for clues. Seems the move only lasts a couple weeks before the pivot.
