Commodity trading is a general term and can be simply divided into two situations. One is the spot commodity trading market based on commodity trading, buying and selling physical objects, nothing special. The other is based on electronic transactions. At present, the market is relatively large. Futures and spot transactions are conducted in the form of electronic contracts, which are generally two-way transactions with leverage of 5- 10 times, which can be used to extract physical objects or as a commodity investment platform.

Physical goods must be delivered or closed at maturity. There is no delivery time limit for spot continuous trading, although it can be delivered at any time or not.
