Do you really believe you would be biting nails? I hope I am not out of line, but if you question your calls enough that the downside would freak you out, you may want to revisit the technicals (or whatever strategy you do use) for a while until it just doesn't bother you...and the wins far outweigh the losses. Confidence DOES make a difference....I lose buttloads when I think I am an idiot....when I am confident in my choices, I do OK.
