No, futures are divided into commodity futures and financial futures. Generally, opening an account is a commodity futures account. Opening an account is free. All varieties can be traded as long as your margin is sufficient when trading.

The minimum capital of financial futures (currently only stock index futures in China) is 50W. Otherwise I won't open an account.

If you want to open an account, choose a regular futures company with low cost. It is best to trade only one variety at first, and then make more varieties when you are proficient.
