If an empty position is forcibly closed, is there another empty position to take over? Yes Because in the market, buying and selling are one-to-one correspondence. There is a price to pay for closing empty orders. Then you can't close the deal without selling the order (short position). (continued)

The market was busy when the liquidation was forced, which was forced by the futures company. No, nobody answered.

Sometimes the market will be out of balance. At this time, in order to control the risk, the exchange stopped trading and closed its position by settlement afterwards. At this time, the bulls were forced to close their positions and the bears were forced to close their positions. Whether the conditions for compulsory liquidation are met. This rarely happens.

The key is that one is the behavior of futures companies and the other is the behavior of exchanges.
