Points that can easily cause trouble in making decisions

- When expectations are too high, test with a small amount
- Write down the terms of withdrawal before considering profits.

- Have you decided in advance the criteria for cutting losses, taking profits, and continuing to hold stocks?
- Are you making judgments based only on social media or short headlines?
