Not to mention the theory, from a practical point of view, detailed delivery data parameters such as PPT or forms are generally obtained from futures companies that serve you/open accounts for you.

From the reality, A-level large futures companies will have more information in this respect; Then most of the futures companies and outlets in the country are operating at a loss, so the specific situation of the business departments around the country will be different. Some poor and small business departments are unwilling to help you do these tedious things that can't see immediate results for free, which may delay something. Relatively speaking, the higher the rating, the bigger the outlets and the better the service.

Of course, it's best that your capital is ok, not too small, and you often do short-term futures trading, then the futures company where you open an account will make every effort to solve your problem.
