#交易策略误区 Trading strategy design is the key to investment success, but many traders often fall into the following misconceptions:

Over-optimization and fitting: Many traders overly optimize parameters based on historical data, leading to poor future performance of the strategy. This "curve fitting" phenomenon allows the strategy to perfectly explain past market conditions but perform poorly in future predictions.

Ignoring risk management: Not setting stop-losses or arbitrarily adjusting stop-loss points is a fatal mistake. Successful trading is not about avoiding losses but about controlling the scale of losses. A lack of risk management can lead to a single loss destroying long-term gains.

Frequent strategy changes: Abandoning the original strategy due to poor short-term performance is a common mistake. Market fluctuations are cyclical, and effective strategies require time to be validated; frequent changes only increase trading costs and instability.

Emotional trading: This includes the "counting money" mentality (overly focusing on profits and losses), revenge trading, and rationalizing losses. These emotional disturbances can lead to deviations from established strategies and impulsive decisions.

Abuse of technical indicators: Relying on a single indicator or using too many contradictory indicators can lead to "analysis paralysis." The ideal approach is to choose 2-3 complementary indicators.

Avoiding these misconceptions requires discipline, systematic thinking, and a long-term perspective, rather than pursuing short-term windfalls.
