To learn how to trade well, I recommend that you pay a teacher who has a lot of experience. On YouTube you can find the person that you think is a professional and you want to learn from him. If you try trading by yourself you will lose more money than if you would learn from a professional
In such case a teacher can help you a lot. He might have good experience so use it. Ask him different scenarios and questions and he will make you understand how things work in better way.
