Chart updated, now 50k 1-minute candle. It's really odd to see 3 big trades (so far) with nothing much in between -- typically 5k shares or less.

Short covering? New (naked) shorting to drive price down? As AlanC say, wash (fake) trades to try to fool people into thinking there's a lot of selling?

As the King says in The King And I, "is a puzzlement."

EDIT: What a surprise. CDEL on the bid AND the ask. (Monkey) business as usual.
