1.5M is a small wall. Besides, even when there is a wall, trade happens. Since yesterday was considered active with 5M+, I would see no reason why there would not be buys/sales.
For my 2-cents, something else is in play here. Curious to say the least. Can't recall seeing a stall this long previously.
Flippers always have been and always will be the "fly in the ointment". Even if/when great PR's come out, they will hinder the upward climb. But IF the developments here are significant, the train will only be slowed. IF, big word !
