Yes, looks like big walk down and MMs getting as many as they can, especially ARCA, they would keep a size between 500 and 999 and move up to the bid and grab some then move a few down in the bid and wait, it drops, they move in grab some and back down again, rinse & repeat. They seem alittle more chill about it right now.
Also lots of matching trades, hard to tell but looks like high then low.
imo someone(s) trying to kill the chart and any EOD run, 4:00 will probly be the bottom of the 15 mins SS... although the ask is just 1 MM away from .007 and it's getting hit pretty good here at .0067
