Today was a systematic and calculated ass ripping. Each time it made a run on the ask, the MMs slowed any rebound and undercut it. 4-5 trades at the ask and it wouldn't budge, but 200 shares at the bid and they'd cut the ask. They had a grand ole time playing games today.
I've seen this so many times I can write the script. I think we could see more of the same a few more sessions and then sensibility will return. Nothing's changed except for the better.
