International gold is a spot transaction, usually also called spot gold, which is the largest stock in the world and does not belong to futures. 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.
