"Most lost on one trade?"
Mnnnhhhh, I remember the day perfectly clear. I was pumping gas and my phone rang. It was my broker suggesting I buy SUNW. I would venture a guess, no-- wait scratch that-- it is not a guess. It is an accurate reconstruction. I bought SUNW at exactly the high --------pfffttt straight down from there, faster than a speeding bullet.
I thought afterwards. I could do that myself (lose MY money), why do I need him?
