The moment rules are established, the information gap is created. Retail investors who follow the rules provide liquidity, while those who understand the rules sit back and harvest. Do you think it's "bad luck"? Actually, it's being ruthlessly exploited by information asymmetry. In this zero-sum market, there is only one way to beat the big players—eliminate the information gap. Otherwise, you'll always be paying for others' cognitive advantages. Doing homework, finding information sources, and deepening understanding—this is not an option, it's a necessity.
