There were at least 9000 shares that were bid above 50.01. Also, there was a total of 312 trades with over 90,000 shares traded above my price. I was attempting to sell only 320 shares and there was also some good bid size like 500 shares bid at 50.26. It all happened within the first 5 minutes of trading and I really think that my broker screwed me.Is there any place i may lodge an official complaint?
