The possibility of night trading in gold futures, the first variety of night trading in two major stock exchanges and four major futures exchanges in the Mainland, is the first sound of the formal securities and futures market in the Mainland entering the "night trading era".

The delivery date of futures can be one week later, one month later, three months later or even one year later. A contract or agreement to buy or sell futures is called a futures contract. The place where futures are bought and sold is called the futures market. Investors can invest or speculate in futures.
