Securities accounts can buy on-site and off-site funds. On-site funds are traded in the same way as stocks. You only need to know the fund code and enter the code directly to buy and sell. OTC funds have a special subscription interface in the securities account. Because the design of each brokerage APP is different, you can consult customer service if you can't find it.

Therefore, it is relatively convenient to purchase funds from securities accounts, and it is also possible to transfer funds off-site and on-site, which is an advantage that third-party fund platforms do not have.
