2. Futures is actually a contract, that is, a contract signed by the buyer and the seller. Because it is a standard contract, the two sides don't have to meet, and it is recognized that the contract is signed by the buyer and the seller. At first, no one has signed a contract, of course, the number of positions is zero. This has nothing to do with the price. If you want to open a position, you must have an opponent who is willing to sign with you. If your opponent is unwilling to open a position in 2000, you can't open a position in 2000.
In addition, the stock futures is not a hand, but a mouth is still open.
