The theme of the futures market is as follows: investors include short sellers, exchanges and futures companies.

First of all, the futures market is a zero-sum market. Some people make money, others lose money. If there are 100 people, then 60% people may lose money, and only 30% people make money. In addition, 10% of the money is actually taken away by futures companies and exchanges, so a few people are making money at any time.
