short story...buying pressure so MMs raise the ask before open to anything above yesterdays close and take your money there....then they usually come back down and "fill" the gap...or if you look on a chart you see a candle that covers part of the day befores candle...If they don't fill it, it remains a "gap" until they fill it...

Could be a day, week, month, or "never"....
