One of the most common mistakes in trading is not having a clear plan. Many traders operate impulsively, without setting goals, entry/exit levels, or loss limits. Another frequent mistake is being swayed by emotions, such as fear or greed, which leads to impulsive decisions or holding onto losing positions in the hope that they will recover. Over-leveraging is also dangerous, as using too much leverage can quickly amplify losses. Many beginners ignore risk management, risking more than is advisable per trade.

Additionally, lack of education and analysis is another issue: trading without fully understanding the fundamentals or without studying technical charts increases the chances of error. Some traders copy strategies without adapting them to their style or market, which can be detrimental. It is also common not to keep a record of trades, which prevents learning from past mistakes. Finally, impatience and the desire for quick profits lead to overtrading or trading in unfavorable markets. Avoiding these mistakes requires discipline, ongoing training, a defined plan, and proper management of risk and capital. This improves the probability of long-term success.
