Not bashing or anything, but those 30s aren't a "fake" wall...It would seem that the rest of their 28s and some of their 29s are probably going to be sold now, which means it is gonna take about 5 mil or some excessive volume pressure to push them higher.
on another note, it would seem that someone is catering to the MMs bids at 29s, but it knocked off 1 MM at 30 so we are now:
4 X 4 on the 29 and 30 with an extra 2 at 31
edit: back to 4 X 5 on the 29 and 30 with 1 at 31
