Fear and greed are two emotions that can be detrimental to a trader's success. Fear can lead to impulsive decisions, causing unnecessary losses, while greed can drive reckless behavior, resulting in significant losses. To avoid these pitfalls, it's essential for traders to manage their emotions, avoid impulsive decisions, and be content with their trading outcomes. By doing so, traders can cultivate a disciplined and rational approach to trading.
You are right, fear and greed is literally what makes some traders unprofitable. Sometimes a trader must have accumulated a huge profit in their trading position but because of greed to make more profit, they can end up losing that little one they have managed to get, while fear (FOMO) can make a trader to take trader on the wrong entry which can lead to lose.
