Guys, Please let me know what you think: Today at 9:24am I entered an orders to short OPG of DHR at 73.92. The stock closing price was 74.00, and the specialist opened the stock at 9:34am at 74.01 on an uptick and canceling my orders at the same time. I believe I am entitled to my fill. The company I am trading through told me that "exchange informed us that in this instance the last sell short order to participate in the opening was entered at 9:03 am." It just doesn't make any logical nor business sense to me that the specialist stops an order flow from their clients 30 minutes before the open, posts no indication to facilitate more orders if he has imbalance, and opens on an uptick. Anybody can explain?
