Perhaps some investor friends may say that they know, but I still don't know how to handle it, don't apply it to practice, or I can't understand it, can't figure it out! I know a lot of truth, but I still can't do foreign exchange investment well. I haven't made much profit from doing it myself. I do it with friends and some teachers from black platforms, and the losses are very serious. In fact, this is also a problem that many mainstream investors in the market are worried about. I want to make a substantial profit by doing my own business, but I am not very professional, I'm not doing well either, I can't find suitable partners to help each other, or there used to be some platform teachers who called for orders, but those platform teachers had ulterior motives and deliberately made me lose money by calling for orders, eating into my position. What should I do?
