Trading is not like an investment that, with little knowledge and understanding, a person can eventually into, and that's why so many people are scared of eventually into trading. There's no way a person can introduce himself without a little knowledge about trading. They said that practice makes perfect, so a beginner deserves so much learning about the trading aspect in order to achieve his goals in the future.
Because once you have everything and every aspect of trading, it will be hard to get higher losses when ever you trade. Some people's includes experience in trading is also good, but as a beginner, experience doesn't matter in the learning process since the experience is also part of knowledge once you finish build yourself and seek for the knowledge the experience can immediately fellow up.
