The story is, there was nothing much happening, the lowest sell order was for around .0012 or something like that. I didn't notice a new sell order until I saw a 17 btc trade in the order history. That took most of the APH for sale at that price, but not all. The rest dissapeared quickly with small trades, some of them were mine. The history isn't large enough to see that far down, but if someone wants to look at the blockchain, you'll see it.

EDIT: You can't miss the spike in the volume. Also, this happened at the same time that Greececoin was added to coinmarketcap, and new buyers were looking at that. Very mysterious.
