#交易策略误区 Trading Strategy: Don't Let 'Perfection' Become a Loss Driver

Beginners in trading often think that finding a 'winning strategy' will lead to easy profits, but they fall deeper into misconceptions:

- The trap of over-optimization: Adjusting parameters repeatedly against historical data may seem to provide a 90% win rate, but it fails in real trading—markets do not repeat yesterday's story.

- Superstitious about the 'Holy Grail' indicators: Buying on moving average crossovers, selling on MACD divergences, blindly following textbooks while ignoring the strength of trends, turning indicators into reverse signals.

- Stop-loss as a decoration: Always thinking 'this time it will bounce back,' only to realize too late when facing liquidation, missing the most critical 'safety clause' in the strategy.

A good strategy is never about precise predictions but about understanding 'recognizing mistakes' and 'holding firm': not hesitating to stop-loss when necessary, and daring to hold positions when trends emerge. Remember, surviving trades are more important than occasional massive profits.
