Always trade what you see, what's in front of you right now.
That's what the smart guys say. But when I, the Undisciplined Trader, apply this rule, I see a five-cent gain and I sell to protect it. What I don't see, is the stock five bucks higher. So I'm nickel-and-diming when I should be big-timing.
I need to learn how to trade what I don't see.
