It is very Difficult to find mentors who give face to face classes , most of them give it online , and for those reasons it is so easy to fool them , because nobody or few are the Ones who have the time to give this type of Activities , I trust in Knowledge, but to be honest I see that the best thing is to read books, first give us a good Internal Argument and then Receive classes , why? To determine if the Knowledge that is being imparted to us is real or not , there are many who sell Smoke and it is a fact that in this world some want to take advantage of others.
Indeed, unless it is close to a community that is focused on trading, maybe it will help more, because usually they will have a certain time to gather, and that's when, there are many discussions that take place. And for beginners, you can also consult with them. It's just that, this kind of method certainly won't be that effective because it's just a chat, not direct technical training.
And indeed, I personally have participated in an online trading class, and really for beginners at that time, it was not easy for us to understand what the mentor explained because it was online. Moreover, usually the class is together with others so when we don't really understand, then we will be quite reluctant to ask about more basic techniques.
