The term "trading psychology" refers to the set of emotional and mental factors that affect a person's decisions when trading in financial markets. It is not just about knowing technical or fundamental analysis, but about how you control your emotions while trading.

Some key aspects of trading psychology:

1. Fear: It can cause you to close trades too early or avoid entering the market, even when there are good opportunities.

2. Greed: It leads you to take on more risk than necessary, hold positions for too long, or overtrade.

3. Hope: Waiting for a losing trade to reverse, instead of accepting the loss and exiting.

4. Regret: Negative feelings about having made (or not made) a decision, which can cloud your judgment for the next time.

5. Discipline: The ability to stick to your trading plan, even when emotions push you to stray.

Good trading psychology involves emotional control, patience, confidence without arrogance, and a mindset focused on the process rather than the immediate result.
