In the futures market, tens of millions and hundreds of millions are large in the eyes of ordinary retail investors, but not enough in the eyes of institutions, let alone national companies. For example, tens of millions of oil futures will not splash, such as PetroChina, Sinopec and CNOOC. Any contract will cost billions, billions, and trading will be calculated by oil tankers. The output of oil-producing countries ranges from hundreds of thousands of barrels to millions of barrels, and every move will affect the international oil price, thus affecting the domestic futures market. Therefore, tens of millions of leverage in the futures market can only be considered as a small level below the intermediate level.
