What is gold futures? Gold futures refer to futures contracts with the gold price in the international gold market as the transaction target at a certain time in the future. The profit and loss of investors buying and selling gold futures is measured by the difference between entry and exit, and the physical delivery is made after the contract expires.

Gold futures are futures, just as stock investment needs to open an account in a securities company, so gold futures trading also needs to open an account in a futures company.

First of all, gold futures trading adopts a long-short two-way trading mechanism.

Secondly, gold futures trading meets the national standard GB/T4 134-2003, and the gold content is not less than 99.95%. In 2008, the Shanghai Stock Exchange stipulated that gold futures should be per lot1000g.

Thirdly, unlike T+ 1 trading in stock investment, gold futures are T+0 trading, that is, they can be sold on the day of purchase.

What is the closing price? The closing price refers to the transaction price of the last transaction of a security before the end of the trading activities of the stock exchange. If there is no transaction on that day, the latest transaction price is taken as the closing price, because the closing price is the standard of the current market and the basis of the opening price of the next trading day, which can be used to predict the future securities market;

Therefore, when analyzing the market, investors generally take the closing price as the calculation basis.

So what is the closing price of gold futures? That is, the closing price of gold futures is the closing price of the last transaction before the end of the day's trading activities.
