#TradingStrategyMistakes addresses the most common mistakes that compromise the execution of strategies, generating debates in the landscape of novice and experienced traders. Recurring criticisms point to the excessive use of technical indicators without validation on robust historical data (overfitting), the absence of risk management plans, and the fallacy of 'foolproof systems.' Trading psychology is another central point: impulsive decisions and lack of discipline often destroy profitable setups. Additionally, dependence on paid signals and unverified algorithms exposes traders to manipulations and liquidity traps. Experts warn that high volatility markets, such as crypto, amplify the impact of these mistakes. The solution lies in rigorous backtesting, emotional control, and continuous adaptation of the strategy to the market environment.
