ETF is a transactional open index fund, which is listed on the exchange and has variable fund share.

You can't buy ETF funds for the following reasons;

1, the minimum subscription share of ETF funds is usually relatively large, and it is difficult for ordinary investors to subscribe in this way.

2. In order to fund on the trading floor of the stock exchange, investors can only purchase through the brokerage platform and need to open an on-site fund account.

3. Fund trading can only be conducted at the opening time of the stock market.
