The futures market is big and full. Like securities, you don't have to worry about the situation that no one takes over when the price is high.
It's totally unnecessary. Your 2200 is a sell-out position, which is different from a sell-out position. The former is flat and multiple orders, while the latter is new empty orders.
95% of futures contracts are hedged and closed, so speculators don't have to trade at all, and futures exchanges don't allow it. Hehe, novices will have some questions, don't worry.
Those who like futures can add me: QQ: 928 142 282.
