A complete trading system, complete trading strategies, position management, stop loss, take profit, cut loss in the opposite direction in a timely manner, and minimize losses are the most important. Just like when we go to war, we need to consider our countermeasures in case of defeat before the battle, rather than being overconfident that we will definitely win. For everyone, you can never make money beyond your cognitive abilities, unless you rely on luck! But money earned by luck will eventually be lost by strength, and this is inevitable! Every penny you earn is a reflection of your understanding of the market!
