The outer disk of gold futures mainly refers to foreign gold futures markets, generally including London gold, new york gold and Hongkong gold. Shanghai gold and Shanghai gold futures belong to the inner market. Specifically, in addition to China's gold trading in grams, the Asian gold trading market is also mainly in grams, such as Japanese gold in Tokyo (priced in yen); However, the gold transaction in Hong Kong is quite special, and its 99 gold is in China's traditional two units (HK$ price).

New york futures gold is the main trading variety in North America and even in the world, which basically fluctuates around London spot gold. However, because it is futures gold, the fluctuation range of its forward contract is often greater than that of London gold.
