How this can make sense? A normal mortal like you and I would put an ask of 6.80 with this kind of bid?
Either it was intended to pull the price 2.16% down or these 1,900 shares know something (???)

1,400 6.620 7.050 4,100 --
500 6.610 7.100 1,000 --
(sorry about the table format... I tried to fix)
