Gaps up in the direction of the near term trend are usually novice gap traps. MM get the retailers who are Kate to the party and don't want to miss the boat. Gaps in the opposing direction of a near term trend are usually professional gaps where they like the news and the prices and they step in before retail and form the reversal.

In my opinion there is selling on lvl 2 as well so I would personally be bidding just above the gap fill to add or get back in.

These pro vs novice gaps do not always hold true
