When you trade, you get things wrong. The only time that becomes a problem, though, is when you can’t admit it, whether to yourself or others. I learned that from bitter experience.

When this one trader got a position as the result of quoting this one customer, however, he always seemed to be wrong, and every time he recorded one of those losses, we would all give him a hard time.
