When trading futures, what does it mean to show that the contract does not support trading?

Right? For example, if you buy a xx2005 contract now, it will show that trading is not supported, because personal accounts cannot trade expired contracts, or if you want to buy iron ore, pta and crude oil, you need to open the corresponding permissions. Because this is an international contract. The general threshold is10-500,000 yuan, and you can open the corresponding permissions, but now the threshold has been lowered. That's what I do. You can write privately if you have any questions.
