There is a gap in CME's $BTC between $91,970 and $92,525, which is the only Bitcoin daily level gap since May 10, 2023.
Of course, filling the gap is somewhat of a mystical concept; it may not necessarily happen, and it's uncertain when it will occur. However, the probability of the gap being filled is indeed quite high, with an overall gap filling rate exceeding 95%.
The filling rate within a year exceeds 90%, and the longer the time frame, the lower the probability of filling. Over 70% of gaps are filled within three months. Statistics on this have been done in the past.
