Differences between buyers and sellers of financial futures contracts
The creator of the contract is neither the buyer nor the seller, but the creator of the contract is the securities exchange center, which operates the operation mechanism of market makers, that is, both buyers and sellers take the securities exchange center as their opponents, so the buyer of the financial futures contract is the buyer. I think the concept of using this fund to pay interest is wrong. It should be a deposit, and both parties need to submit it.
