It was a Citibank trade as I've been told and it was both. Indeed someone wanted shares at 18 and the seller was willing to take 18. The seller originally offered the shares at 22+ but no takers over time and the 17K will come in handy I'm sure. Now Nite has moved back to its' customary position on both sides of the market at 18 and 20.4. Wish the ask wouldn't keep dropping bit by bit. That pulls the other mms along for the ride. In fact as I typed this we dropped to 17.1/20. A bunch of shares moved quickly. No fun watching this today.
