The NYSE website states that, "8:30 am - 9:00 am Imbalance and Paired-off information is disseminated every 5 minutes for each security 9:00 am - 9:20 am Imbalance and Paired-off information is disseminated"
My question is that if order imbalances are seen at 8:30am, what is to stop the market from getting manipulated by large opening orders being placed and then cancelled before 9:28am?
