We see these 10$ trades all the time in the OTC. L2 reveals that MM's like NITE who are always on the ask with huge lots and is clearly short do this with every stock in pinky land. CLEAR MM MANIPULATION.
That's not retail. NITE is some institution that is apparently allowed to short....the flip side is that NITE is also the reason why penny stocks make such huge moves once retail buying pressure begins, then NITE is forced to cover.
