So I realized there are so many things that can't be taught in trading.
One major thing I know can't be taught is the psychological aspect of trading.
No matter the number of videos you watch on this, you need to learn your psychology by Yourself! This is just a fact!
What other things can't be taught in trading?
In addition to trading psychology, we also have "discipline". You know, each of us are born with different personalities. therefore, it is a crime to impose discipline of one person as a person. I think we should learn a lot about indicators and how to manage capital. When we have enough background knowledge, we will trade with a small amount of money to practice psychology and discipline. That would be the best way to become a professional trader.
