Not wrong in my opinion. Other parties can help traders to find out how to trade, but do not always depend on other parties. Just know the basics after that, make the market as the main object to control themselves of what will be done next while remembering that it will not always be in a profitable position. Even professional traders also experience loss.
What you said is very true, of course we should not continue to rely on other parties in trading and it would be better after we understand the basics of trading well, then we can try directly while continuing to learn and it is also important for us to be able to use funds that we can afford if we fail in the trading we do. It is true that even professional traders have experienced losses but they can use the experience they have gained during trading to make a profit on another occasion.
These days there are many who trade using assistive technology. I do not blame those who use the help of machines or the like in trading, but I do not think it is good to always rely on such help. For example, those who use trading bots.
Losses are a certainty that traders will receive, but trying to make a profit is the goal of trading.
At least learning manually from those who are more senior in trading can provide valuable experience that allows them to collaborate on trading strategies.
The use of those technologies are for those who already got that confidence but learning the process it's best to do it manually together with the knowledge you earn from reading books or watching video tutorials having a hands on experienced will definitely a good factor to ake your success, as in each trading sessions that you take you'll learn on it both on your losing trade and winning trade you should take a good note to make a better adjustment for your next trades.
