OTC Futures (English, futures) are completely different from spot. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with some bulk products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. OTC futures refer to futures trading in which the exchange is located outside Chinese mainland. The products of American, British and London exchanges are usually futures contracts. Some American futures contracts, such as soybeans and copper, will have an impact on domestic futures prices. Domestic investors can refer to the external market. Large producers and traders can also hedge spot trading losses according to the external market. At present, the well-known foreign futures forum in China is the speculators forum.
