This is a 5 minute moving weighted average pattern looking at the Mondays for the past year falling on the weeks of the FOMC meetings. I used a straight average for the first five Mondays, then weighted the last 3 Mondays falling on FOMC at 15% consecutively (7/25/22, 9/19/22, 10/31,22).
Historically, the high clocks in at the 9:40-9:45 interval, followed with a steady decline until 12:10 PM. Look for choppy boxable action from 12:25 to 2:25 with low opportunity for scalping (You should take a walk here, go to the gym, sing a song, or read a book during this time).
Finally we have a good historical liftoff with steady rise starting at 2:45PM until close.
