The insights the turtle trading method gave me:

1. Without discipline, even the best technology is garbage. A system with a positive expected value is worthless if it cannot be strictly implemented.
2. The success of trading does not depend on how accurately you can predict, but rather on losing less when you're wrong and earning more when you're right. The decision-making behind this relies entirely on mindset and management, rather than predictive techniques.
Discipline ( - The most important mindset
Ignore Fear and Greed: When the market is booming and the system prompts you to chase the rise, fear will make you afraid of "taking over the position", but discipline requires you to enter the market. When the market is crashing and the system prompts you to stop loss, greed and a sense of luck will make you "wait a little longer", but discipline requires you to decisively cut your position.
"Robot" execution: Turtle traders must execute each signal like a robot, without any emotional bias. No euphoria when making money, no frustration when losing money, just calmly executing the next step.
Consistency )Consistency(
Abandon subjective judgment: The biggest temptation is: "This time feels different, this signal might be bad, I'll skip it." Once you start replacing systematic rules with subjective judgment, the positive expected value of the entire system is destroyed. Success comes from the long-term adherence to the probabilistic advantage provided by the system, not from the win or loss of a single trade.
Pain Tolerance )Pain Tolerance(
Embrace Losses: If your trading system has a win rate of less than 40%, it means that most of your trades will end in stop losses. You must wholeheartedly accept the idea that "losses are the cost of trading" rather than viewing them as failures. If you cannot properly view losses, it is easy to become mentally crushed and abandon the system after several consecutive stop losses.
Patience )Patience(
Wait for signals: Stay in cash when there are no signals, and do not be disturbed by market noise.
Holding profitable positions: "Cut losses, let profits run" is the core philosophy of trend following. However, the process of "letting profits run" can be very painful; you may have to watch a significant portion of unrealized gains evaporate before finally capturing a major trend. Those without patience may exit profits too early, thus failing to recover the costs of multiple stop-losses.
