One common trading strategy mistake is relying too heavily on emotion rather than logic. Many traders enter positions without a clear plan, chasing quick profits or trying to recover losses, which often leads to poor decisions. Overtrading, ignoring stop-loss rules, or risking too much on a single trade are also frequent errors. Some traders follow trends blindly without understanding the market context or fail to adapt when conditions change. Neglecting risk management or skipping analysis can quickly turn gains into losses. A successful strategy requires discipline, patience, and a willingness to learn from past mistakes rather than repeat them.
