Can B's securities company operate the transaction when opening an account in a securities company? thank you

Trading is based on the trading platform of securities companies. No matter where you open an account. No matter which securities company you trade in. An account opened in China Merchants Securities can only be traded through the trading platform of China Merchants Securities. No matter where you are, you can trade as long as you can use the trading platform of China Merchants Securities. At present, there are mainly online transactions and telephone and on-site transactions. As long as there is the internet, online transactions are possible. As long as you can make a phone call, you can make a phone transaction. On-site transactions must go to the scene of the securities company. They say you can trade anywhere.
