Hehe, there's no use at all. If everyone makes money, no one will lose money. The most important thing about trading is that no one should trade according to only one method; following the crowd will only cause you to lose money, because the 28 rule of law reverse thinking is the essence of zero-sum trading, remember never to be that majority. If you become that majority, you will lose money. This is an eternal rule, so I never share, never give suggestions, and never blindly follow suggestions, and keep thinking independently to stand out.
