#TradingStrategyMistakes Common mistakes in trading strategies include the lack of a plan, trading based on emotions, ignoring risk management (such as not setting stop-loss), overtrading or impatience. It is also a mistake not to adequately research the market, to rely too much on software, not to understand leverage, and to overexpose positions. Finally, the lack of a trading journal to learn from mistakes and overconfidence after gains can be detrimental.
