I have watched the bids dancing around on DIRX's L2s. Very interesting, esp. cuz there's little volume.
I'm not sure if they're trying not to push it up too far. Maybe they're trying to persuade the ask to come down a bit.
I think someone is accumulating, but not eager to get into a bidding war, or trigger any volume/PPS alerts.
