#TradingStrategyMistakes is a hashtag that encompasses a series of common mistakes that every trader should know and avoid. One of the most frequent is the absence of a well-defined plan: many jump into trading driven by emotion or market 'noise', without a solid strategy. Another mistake is the failure to adhere to the rules of their plan, especially when emotions like fear or greed take over. Additionally, underestimating risk management can lead to devastating losses: not setting stop-losses or risking too much on a single position are dangerous choices. Overtrading, i.e., making too many trades in a short time, is also a mistake that often arises from the haste to recover losses or the belief of "being on the ball". Finally, ignoring post-trade analysis prevents learning from one's mistakes. Every mistake is an opportunity for growth, but only if recognized and corrected.
