#交易策略误区 Counter-Trend Operations**: Blindly bottom-fishing or top-selling, ignoring the strength of trends. Trying to catch rebounds during downturns or taking profits too early during uptrends can lead to repeated losses. Trading with the trend is safer; it is essential to wait for trend confirmation before entering the market.

2. **Over-Optimizing Strategies**: Overfitting parameters to historical data can lead to strategy failure in the future (e.g., 'sneaking price' or 'future function' traps). One should avoid pursuing perfect backtesting and focus on the adaptability of the strategy.

3. **Ignoring Risk Management**:

- **No Stop Loss**: A lucky mentality can lead to expanded losses; reasonable stop-loss is key to survival.

- **Out-of-Control Positioning**: Rushing to close positions when profitable and averaging down when losing disrupts capital management discipline.

4. **Frequent Trading and Emotional Decision-Making**:

- Chasing short-term fluctuations while ignoring the larger trend increases friction costs (transaction fees, slippage).
