Yes, open-end funds only need to open a fund account, and closed-end funds need to be purchased through a securities account.

1. Open-end Funds refer to a fund operation mode in which fund sponsors can sell fund units or shares to investors at any time according to investors' needs when they set up funds, and can redeem the fund units or shares issued outside at the request of investors. Investors can buy funds through fund sales agencies, so that the assets and scale of the fund will increase accordingly, or they can sell their fund shares to the fund and recover cash, so that the assets and scale of the fund will decrease accordingly.

2. close-end funds belong to trust funds, which refer to investment funds whose fund scale has been determined before issuance, fixed within the specified period after issuance and traded in the securities market. Because closed-end funds are traded in the stock exchange by bidding, the transaction price is affected by the relationship between market supply and demand and does not necessarily reflect the net asset value of the fund, that is, the transaction price of closed-end funds has a premium and discount phenomenon relative to its net asset value. The practice of foreign closed-end funds shows that the transaction price often has the price fluctuation law of premium first and then discount.
