You can't open an account for the first time, because iron ore and options require that the available funds be above 654.38+million for five consecutive trading days, and financial stock index futures and crude oil futures require that the available funds be above 500,000 for five consecutive trading days, and you can only open an account if you meet the conditions. For the first time, you can only open commodity futures accounts in Zhengzhou, Dashang and Shanghai Stock Exchange (no special requirements), but if you have opened all of them in one futures company before and want to open an account in another futures company, you can open all of them.
