Trading is not just focused on learning theories and methodology but it’s more on application and skills development. If you fail to do that, you will never be a reliable trader. This is why mentors are here to guide those beginner traders to practice and develop their skills as a trader, which I think is certainly hard to develop just by reading all those resources in trading. The trading market is still different compared when you are looking it at some of your videos and reading resources, trading will be more enhance with consistent trading practice in the market.
I have said this because trading is not only learned at one level, because trading will be much more experienced when people can improve their skills by engaging in it. Mentors and learning are really needed because with knowledge people can improve their skills slowly.
Beginners who rely on their own abilities will find it much more difficult to develop when they don't have many references regarding trading because a person's abilities will definitely vary.
To practice trading better people need knowledge about trading and the methods can be different. If people dare to take risks, being directly involved in trading by combining knowledge will improve their trading skills much more quickly.
