First choose a good brokerage firm, and then choose a futures company. Your broker should be able to bring you profits and help you set up your own trading system. If he can't, then he is basically unqualified, but he will do pure business. There is also the problem of handling fees. Futures commodities receive unilateral fees, and stock indexes receive bilateral fees.

If you don't need the above services, you can ask for the lowest handling fee. Other services of futures companies are basically useless. In addition, the so-called R&D staff of futures companies give lectures to everyone on weekends, and many of them have no firm offers, so they can be said to be pseudo-experts.

Just bring your ID card and bank card when you open an account, and the stock index needs more preparation. We can handle it.
