Hello, the most forward contract of precious metal futures is almost a year. Because most varieties are transferred to the main contract in advance, they will not be delivered until one month, but the main contract will be moved about two months in advance. Delivery month cannot be entered for natural person account. Secondly, for some varieties, such as copper and zinc, the main contract changes very quickly, usually about two months, so we should pay attention to the position of the contract. The continuous decline in positions indicates that the main contract may change. I wish you a happy investment. If you have any other questions, please feel free to communicate.
