There are many reasons why someone may win in the demo but lose in real trading. Here are some of the most common:

- Lack of discipline: In the demo, there is no real risk of losing money, which can lead to riskier and less disciplined behavior.

- Psychological effect: Real trading involves emotions like fear and greed, which can lead to irrational decisions.

- Differences in market conditions: The real market is much more volatile than the demo, so strategies that work in the demo may not work in the real market.

- Position size: In the demo, traders can use a smaller position size, which may result in smaller profits but also less risk.

- Lack of experience: The demo is not a substitute for real trading experience. It is important to practice with real money to learn to manage emotions and develop a solid trading strategy.

It is important to remember that trading is a continuous learning process. There are no guarantees of success, even for experienced traders.
