Nice beginner guide and advice, but you failed to mention an important point that can help the beginner to minimize the risk involved in trading and reducing losses which are to trade with a small amount as a beginner and not get greedy by putting in large sums of money because of the potential profits most especially in future trading which is almost same as gambling.
Investing with a bigger amount at first due to greed will only increase the chance of losing. Hence, it’s not advisable to do it, instead start with minimal amount and never be greedy enough to expect quick returns because that will lost your focus in trading. Know that trading requires more focus and persistence, that’s why you need to trade at your own risk, and at the capital you’re free to lose.
