Spot gold (also known as international spot gold and London gold) is a spot transaction, that is, it is delivered within a few days after the transaction is completed. Spot gold is an international investment product, which is an investment and financial management project formed by gold companies establishing trading platforms and conducting online transactions with market traders in the form of leverage ratio.

It is often called spot gold and is the largest stock in the world. Because the daily trading volume of spot gold is huge, the daily trading volume is about 20 trillion US dollars. Therefore, no consortium or institution can manipulate such a huge market artificially, relying entirely on the spontaneous adjustment of the market. There is no banker in the spot gold market, and the market is standardized, self-disciplined and sound.
