Newly issued ETF funds on the exchange can be purchased on the official website of the fund company or a third-party agency platform. Securities companies are also agency sales agencies. It is generally recommended that investors purchase at a securities company. After the securities company has subscribed, wait for the fund to be listed. Transactions can be made directly to sell.

For subscriptions on the official website of the fund company or other third-party sales platforms, after the fund is listed, it needs to be transferred to custody before it can be sold. Investors cannot sell in time, but newly issued ETF funds are off-site. There are relatively few third-party agencies selling on behalf of others.
