How to say it, event contracts cannot be forced. If the trend is not right, you must immediately change direction. The worst thing is to go down a path without turning back.

If you have judged the trend correctly, but it is still opposite to your direction, do not hesitate. If the market changes, immediately shoot in the opposite direction.

This thing is against human nature, and you cannot win against it.

Also, do not think of it as gambling, but rather as judging the movement and trend before opening a position.
