If you open an account through the intermediary of a futures company, you need to wait for a 24-hour cooling-off period after submitting the information. If you submit information to open an account in the morning, it will not be approved until around noon tomorrow at the earliest. The account manager said to open in the morning and leave in the afternoon, so open in the afternoon and leave the next morning.
Futures, completely different from spot, are actually tradable goods (commodities). 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.
