Just like you shouldn’t practice your basic martial-arts forms in the ring where your mind is more focused on pain avoidance then executing the tactic correctly, a novice shouldn’t begin trading with real money and real consequences. Only once you’ve amassed significant practice in a safe environment where you can conduct your technical and fundamental analysis without being emotionally distracted should you begin to trade with real money. And when you finally start, don’t jump straight into the ring with Bruce Lee. Begin tentatively, gradually, slowly increasing your trading exposure over time as you become accustomed to the increasing levels of risk. How do you know you’ve moved too far, too fast? If you are finding it’s becoming harder to sleep at night, either because you are worrying about your trades or you are excited about your gains, then you have moved into the realm where your emotions are going to have too strong an effect. You are going to start making poor, emotionally-clouded decisions and so it is time to scale back.
