I am having a problem entering a call symbol. I read Mark's 9/30/10 post and when I looked up the SPY Dec. 15 175 strike I found SPY151219c00175000. I was unable to enter anything more than "SPY" in the symbol box.
What do you think I am doing incorrectly?
My Mistake! I thought I had the number lock on. Operator Error. Problem Solved.
