The top trading principles: never judge price movement—only handle it!

All you need to do is think: what will you do if it goes up, and what will you do if it goes down? If it goes up, when should you exit? If it goes down, when should you buy?
That’s all there is to trading.
Judging whether it’s going up or down is God’s work, not a human’s. If you insist on taking God’s job, then if he doesn’t smash your job, who will he smash?
