Jag, those have a different "flavor" than what we were used to seeing. Buying was coming in pretty good at the end. Those nice even trades at the ask are likely IMO real buys that went through at the very end.
That's a lot different than the oddball share size and 4 decimal place price that we normally consider our beloved AH mystery.
Just mentioning this because I don't view these as being anything remotely like our previous typical AH prints :) While they are still "t" trades and AH, these are easily explainable IMO :)
