1, foreign exchange trading training takes about 4 hours.

It takes a long time to practice. After you master the basic theory and are familiar with the application, you can learn the intermediate theory in two hours.

I don't know how long it will take to get familiar with practice after learning intermediate theory. According to my personal understanding, I will learn advanced theory again.

4. That's basically ok.

I hope my answer is useful to you. Be cautious in investing. Thank you.
