Full trading system, full trading strategy, position management, profit and loss realization, timely counter-trend cutting losses, and strive to minimize losses is the most important, just like we fight in war, we must think about how to deal with defeat before we start fighting, instead of relying on our absolute confidence in winning. For everyone, you will not make profits beyond your cognitive abilities unless you rely on luck! But the money you make with luck will eventually be lost based on strength, and this is inevitable! Every dollar you earn is a manifestation of your abilities in understanding this market!
