One of the most common mistakes in trading is to operate without a clear strategy. Many traders act on impulse, following emotions or recommendations without analyzing the market or defining specific objectives. This can lead to hasty decisions and overtrading, increasing the risk of losses. A trading plan should include precise rules for entering and exiting the market, loss limits to protect capital, and realistic goals. Discipline is essential to avoid deviating from the plan in the face of volatility. Without a well-defined strategy, it is easy to fall into repetitive mistakes and lose control over operations, affecting long-term results.
