I don't think it's necessary, it's enough to know the basics of trading by learning through several sites that discuss trading, but the most important thing in my opinion is to know a lot of things from the experiences of friends or people who trade first.
Sorry, I don't really agree with this.
Kowing the basics of trading is very important, at least we know the basics. If we only pay attention to our own experiences or the people's experiences, it may be different from our own condition.
Many people are following others in trading and they do not really understand what they are doing, they are only following other people's experiences in which they are different from the newbies.
I will suggest learning at first, basic knowledge is very important to make us learn more again to the other knowledge.
