Many traders underestimate how common #TradingStrategyMistakes are, especially in the early stages of their journey. One major mistake is jumping between strategies without proper testing or understanding, leading to inconsistent results and emotional decision-making. Another common error is neglecting risk management—trading without a stop-loss or overleveraging can wipe out gains quickly. Over-optimizing a strategy based on past data, also known as "curve fitting," can make it fail in real-time markets. Traders must also avoid letting fear or greed override their plan. The key to long-term success is learning from mistakes, refining strategies, and maintaining discipline with every trade.
