I spoke to a tutor who teaches trading, and he said for his lectures, he teaches for an extended period of nine months for anyone who wants to learn trading from him.
If he said you need to learn for 9 months, it is actually his personal assumption. IMO, there is no exact time about how long we need to learn trading. We even will never stop learning trading forever because there will be always something new in trading. However, for learning about the basic things in trading, I don't think it must take 9 months. For people who can learn fast, I think he only need for 1-2 weeks only.
Exactly every tutor as is on way of teaching i think before you understand you will spend a month before you understand everything in trading but some professional teach newbies just in 3 weeks and they will understand everything but he depends on how you pick things early because everyone has different brain, trading is good but because of is high risk many people are scared to take risk and don't know much about trading because am only focusing on investment, because he minimized my risk because they said you should only invest what you can afford to lose in trading am just learning trading gradually on YouTube but am not deeply with it yet, if someone is ready to learn how to trade and he focuses on it very well I think in just 2 to 3 weeks he should have understood everything on trading and he can stay on without any mentor that will guide him again he can start taking is on risk without any helper because he should have understood everything if he is serious in that three weeks, the reminder on trading is invest what you can afford to lose since he has big risk and that is how he has huge profit.
