No. It doesn't. Like every other profession, trading is a skill to be learnt and it's one where you learn from textbook, your experience, other people's experience and also your intuitive. It also takes time and patience to start getting consistent results. The difference between more experienced traders and those who aren't is the fact that they've seen it all in the market ~ flashes crashes, epic pumps, ranges etc. You just have to consistently practice and keep practicing. If it doesn't go as planned, you go back to the drawing board and figure out what you did wrong and the next steps to recovery.
