I respect your advice, but theory and practical are both different in real life. In classes, they only teach theories about how to control emotions, but when put into practical, these theories do not work. Especially in trading, we put our order bravely, but suddenly our trade gets the opposite turn. Our emotions pressure us to stop the trade, and in the end we get the loss. these types of traders called "panic traders," and I was one of them. I tried trading, but most of the time I lost my money, so I quit.
