1. Day traders: Due to the unfavorable factors for day traders in the commodity market, they must first recover trading costs in order to make a profit; transaction fees are the greatest expense for day traders.

2. Those who are unable to trade: Those who are obsessed with the fluctuations of account balances during trading are destined to be failures in the commodity market. Excessive worry about account balance changes can override market judgment, leading to defensive trading, which causes traders to lose objective judgment.

3. Emotional traders: The market is ruthless; if traders have obvious personality flaws, the commodity market will exploit them. Most professional traders will mention that their success is based on counteracting emotional impulses. Even if you do not experience emotional turmoil, participating in the commodity market is already challenging, let alone the added burden of emotions. A trader who can manage their emotions does not mean they won't experience strong emotional responses to trading plans, nor does it mean they can completely prevent emotions from influencing their trading, or that they can become entirely emotionless in market transactions. It means they have the ability to recognize emotions (including fear, greed, anxiety, stress, unrealistic hopes, self-doubt, etc.) for what they are. Gradually understanding that having emotions is normal, but emotions are not reliable, allows for the development of a strategy to manage emotions in trading. Having emotional intelligence is normal, but it should not be overemphasized.
