先有風險管理，才會成就交易人生

This is a fact. In order to be successful in trading, it doesn't matter whether you are right or wrong when placing a trade. What does matter is that when you are wrong, you lose a little bit and when you are right, you maximize your gains. Why do most traders (especially day traders) lose?  They don't have prudent risk management skills. End of Story. Now, a lot of folks may say, "but the newbie trader doesn't know how to pick entries and exits". While that may be true for some, the real issue is that when they are wrong, they stay married to a position, or add to a position in order to not admit failure. Your best bet would be to learn to embrace failure, learn to shrug it off, learn to admit when wrong and learn to stay in trades that are winners. You see, Prudent Risk Management is not just about placing an initial stop---it's also about managing a winning trade. Remove the focus from high winning percentage. Retrain focus on losing a little and making a lot.
