One of the most costly trading strategy mistakes? Thinking a single win proves your method works. Without proper backtesting, risk management, and emotional control, even “winning” strategies can fail fast. Many traders over-optimize, trade too frequently, or rely on gut feelings rather than data. A strategy isn’t just entry and exit—it’s how you handle losses, volatility, and doubt. Smart trading means having a plan, sticking to it, and refining it based on performance, not emotions. Avoid shortcuts. Mistakes multiply when strategy is missing.
