Contract delivery month:1-65438+February. Futures should perform the functions of price discovery and hedging, and the most important thing is to return to the spot. Delivery is a bridge between futures and spot (the risk-free arbitrage of futures and spot spreads is based on this). 1-65438+February means that there is a delivery contract of 12 months to choose from. For example, it is February 2008 1, and the specific codes of these contracts are: AU0806, AU0807, AU0808, AU0809, AU08 10, au081,au08/kloc-0. In short, there are 12 contracts to choose from throughout the year. When a contract is delivered on the last trading day (see the last trading day), a new contract of the same month will be generated in the next year.
