At present, stock index futures are the only futures products in China that can be delivered by legal persons and individuals at the same time. As long as the deposit of 100% is paid one day before the delivery date, you can participate in the delivery on the delivery date. In fact, it is to retreat more and make up less, and finally it is reflected in cash.
Other futures varieties can only be delivered by legal person households (gold is stricter, and only qualified legal persons can deliver).
