Many traders make common mistakes such as trading without a plan, letting emotions drive decisions, overleveraging, or chasing losses. They often ignore risk management and fail to set stop-losses, leading to heavy losses. Impatience and unrealistic profit expectations can also result in poor judgment. To avoid these pitfalls, always trade with a clear strategy, manage risk by using stop-losses and proper position sizing, and stay disciplined. Avoid emotional trading—stick to your plan even during losses. Keep a trading journal to learn from past trades and continuously improve your approach. Education, patience, and consistency are key to long-term trading success.
