Trading isn't easy. I do a bit of trading periodically. I have done alright on some trades and poorly on others. One of my strategies is to only trade assets that I believe in for the long term. That way if I get stuck making a bad trade I still feel comfortable holding it long term. It is nice that most learning information can be found on the internet for free as you mentioned.
Good luck with your trading endeavors!
Yes, it is definetely not easy and can take years before one understands it completely and make profit. The first few years are mainly for making many mistakes and understanding why you made these mistakes and how to avoid making the same mistakes again. I am super happy I could find all information online for free. Many people spend 1000's of dollars to pay a Forex expert for teaching them golden strategies but at the end you are the one who smashes that buy or sell button. It's all about controlling your emotions and greed. You too good luck with trading!
