$BTC Closed most of its CME gap yesterday although there's still a small part of it open.
Yet again, the market opened up with a gap after a weekend move which closes the same week. This one was a bit larger than usual and also took longer to fill. Most of the previous ones only took a day. This took 3 to 4 days.
Can be a good level to keep an eye on in case price does decide to do one more drive lower to take out those lows.
