Its shorts... They have been shorting and covering atleast part of there position almost Dailey... Today they covered around 4 05. Selling into hidden seller as to keep price action down . . i watched the tape and checked available shares before and after . ... So they let price action breathe a bit .. Short it then cover back low buying into a seller ..who probably spent the day or previous days accumulating shares for such purpose ... They are playing both sides .... And controlling the action to line there pockets .... U can see it on the charts ... Flat price action followed by these spikes .. ..

That's where they take positions walking price action back down and then cover into themselves or there buddies ...

Market makers

My 2 cents ....
