You are so strong! Do it all! Great wisdom depends on the market. The software that the broker gives you should be divided into two parts. One is the stock trading system, which is used to place orders to buy and sell stocks. The other is quotation software (which has the same function as great wisdom), so if you are used to great wisdom, you can use it to look at quotations and place orders with the trading system of brokers.

Do you mean opening different accounts? If you mean an account, you can open only one account. Because both brokers and futures companies will set up an independent account for you to exchange funds with your own account in the bank, then you can make the accounts of brokers, futures companies and foreign exchange companies correspond to the same bank account, so that you can allocate funds in three markets with one account.
