So what? For the exchange, compulsory lightening is a means of risk control, which may be carried out if the unilateral market continues. In layman's terms, for example, if a car suddenly fails to brake on the way, it must be stopped by external force. Of course, the effect depends on the speed and the strength of external force. There are two kinds of futures investors: speculation and hedging arbitrage. When forced to reduce positions, it is of course a brake for loss-making speculators. Useful brakes at least have a buffer force and a chance to unwind; Of course, it is not good news for profitable speculators. Profits were forcibly interrupted. If you forcibly reduce your position, it means forcibly closing your position. For investors who hedge arbitrage, it means that there may be risks in hedging arbitrage positions. Perhaps there is no big risk in this position, and there will be a big systemic risk because of this system. The risk should not be underestimated, and it should be handled properly as soon as possible.
