It is important to know the basics of trading, and to be honest, one can learn the basics of forex trading very quickly.
However, it is really important to understand that trading is fundamentally a risk management business. Most traders don't lose because they don't know how to do technical analysis, it is the relationship with loss.
It is really hard to accept losses, and protecting your capital at all costs. Most really good traders are really good at controlling losses, even when it means quickly accepting that you are wrong.
Believe me, it is really hard mentally. Technical analysis is not hard, that is why analysts are not traders. Anyone on youtube, who has zero risk on a trade, he/she can say anything. But when you have your position in the market, depending on who you are as a person, you can feel different emotions.
Also, I'll add that with experience you will learn how the instrument you trade moves, a lot of it is muscle memory, because you have seen that move over & over.
If you know someone who is actually profitable in trading, then the learning curve to profitability can be faster (although it is not guaranteed). Because you can see the trader managing their risk, and you will see them doing what they know.
But never pay anyone to teach you about trading.
