I always had problems with the opening orders on nyse. I have tried numerous different systems from spread sheets to whatever. It seems like a crap shoot with the specialist having you at his mercy. I know that all the good traders never want to let you in but if anybody has ideas that might help me figure out a game plan that would be great. I stopped trading them when I got an opg buy fill in lehman (.80 spread) and the next second it was down 2.00. For some unknown reason my p&l went down at the same time. When the stock shot up I got out thinking that I broke even but in reality I had lost a dollar and $600 in my account. It all seemed to me like I got scammed and have not put an opening order since.
