❌ One of the most common mistakes in trading is not choosing a bad strategy, but failing to respect it. Many traders design a profitable system, but when facing the emotional pressure of the market, they end up improvising. Another frequent mistake is overtrading: forcing entries out of fear of 'missing the opportunity'. It is also a major mistake not to place a stop loss or to move it without technical justification. Finally, underestimating risk management is lethal: without discipline, even the best strategy cannot survive. True success lies not in always being right, but in knowing how to manage both gains and losses wisely.
