If the TA wasn't gagged here we would be able to call daily and get an accurate number for the amount of shares outstanding. That's their job. Nate prefers to keep that a secret 3 months at a time.
The T-trade is the market maker balancing out a partial fill of a larger order that they had been working all day. They short during the day, then cover with a T-Trade so they can get their commissions.
There is still A LOT of stock left in that SELL order they are working.
