I would suggest that a 500k wall placed on the ASKS near the end of the day was not done so to lock in profits. A smart trader would not be so dumb to scare away potential buyers buy placing on huge sell offer.
There still seems to be an attempt to cap the share price and dropping a 500k wall at $0.70 was blatantly done to stop this rally in its tracks. Let's see if some technical buying kicks in tomorrow to call their bluff.
