I keep on reading about how people should stick to the plan they made, even if it implies an occasional loss. Still, besides the common beginner's mistake to forget the plan (and lose money), I also read about discretionary trading. I have to assume different people just do things in different ways, but I would say it's true that a human being (who can at least read news better than any mechanical system), can definitely have an advantage. So I would like to ask: 1) is your system fully specified? Do you define exact values and conditions for entry, exit, stop, and so on? 2) do you *always* stick to it? 3) if you answered yes to both 1 and 2, and your system is not automated yet, why don't you automate it?
