Many traders fall victim to common trading strategy mistakes that can lead to consistent losses. These include overtrading, ignoring risk management, lacking a clear plan, and letting emotions drive decisions. Chasing losses, failing to set stop-losses, or abandoning a strategy too soon are also critical errors. Overconfidence after a few wins can lead to risky trades, while fear after losses may prevent rational decisions. Another frequent mistake is not adapting to changing market conditions or relying too heavily on outdated indicators. Successful traders learn from these pitfalls and refine their strategies through discipline, analysis, and continuous learning.
