When the session is about to close with offers stacked like the way it was, it does not make sense to hit the offer today but better to protect the bid side a few ticks below where the offer is but above where the open was. That happens to be 0,0019for the day. The sellers make a small margin if they hit me (we know where they bought) and if 0,0019 is not good enough, NITE (who is the seller) will build the bid above me to get people to hit him on the offer. You should have seen that on L2. As soon as the bid went in for 0,0019 (me) a NITE player came in with 0,002. Whether they hit me or build the bid, this closes the session nicely GREEN.
