I think these are dark pool orders happening. Dark pools don't appear on taters.net as I understand them.
Dark or not, a bid of $1.63 should be filled before a trade at $1.60 occurs. Otherwise, the seller isn't getting the best price available. That said, I don't know how to read the taters.net data. I see the trade at $1.60, but where it the proof of the bid of $1.63?
