I've noticed over that last few months that the NYSE closing prints are increasingly in the oppsite direction of the last posted regulatory imbalance. To put it simply, stocks with buy imbalances are closing on minus ticks and stocks with sell imbalances are closing on plus ticks. Take AEP, 377,000 to buy, closes down 7 cents on 890,000, or WYE, 749,000 for sale, closes up 13 cents on 1.4 mil. I can cite hundreds of examples from just the last few days. Have the DMM's changed their closing procedures? I haven't read anything about it on the NYSE site. Do any of you guys know what's going on? thanks!
