Stop getting entangled in system theory. No matter what your theory is, you cannot get every trade right, so you must set stop-losses.

A high win rate in the short term means nothing; achieving a 50% win rate or higher in the long term, with a risk-reward ratio of 2:1 or more, and fewer consecutive losses, combined with reasonable position management, is what demonstrates a high tolerance for error. Only in this way can profits have long-term sustainability.

Trading does not require complex theories; it only needs basic probability knowledge. The market is ever-changing, past experiences may fail, and market conditions are always unpredictable. Analysis and judgment can easily be influenced by subjective emotions. We must acknowledge the limitations of being human and our own insignificance. Realizing our own smallness will help us maintain respect for the market. The core understanding is to recognize that the market is constantly changing, infinitely complex, and contains countless variables. The only thing we can trust is the system's rules.

Use unchanging rules to face a changing market; replace subjective analysis with systematic rules. Rules that align with market trends, rules with probabilistic advantages, are the only things we can rely on in this turbulent market; your analysis is not reliable in the long run.

Exiting is not important; entering is extremely important. Entry rules are crucial; a good start is half the success. Whether you can immediately make a profit after entering directly relates to long-term win rates, and win rates are a prerequisite for risk-reward ratios. If the price does not quickly move away from your entry cost, do not expect to achieve a high risk-reward ratio. A perceptive trader should crazily study entry points and summarize refined, advantageous, and simplified entry mode rules.

As for taking profits, if you often make profits after entering and the price quickly moves away from your stop-loss, taking profits is not a problem; both active and passive profit-taking are easy. I did not mention trends because they are discovered through testing, not by observation. I emphasize again that studying entry points is crucial because you cannot avoid setting stop-losses. Therefore, entry points are vital. The rules and patterns for entry signals must be advantageous and easy to recognize; only simplicity can adapt to the complex market environment, which leads to a high tolerance for error.
