Yes, the bidding time and trading rules of ETF funds in the morning are the same as those of stocks. The call auction time in the morning is: 9:15-9:25 a.m. on the trading day. During this time, investors can freely make trading declarations, and the system will match the effective entrustment. The price with the largest trading volume is the opening price of the day. If there is no trading in call auction, then the opening price of the fund is yesterday's closing price.

ETF funds take a specific index as the tracking object, and buy some or all of the constituent stocks in the index in order to obtain the same income as the index. ETF funds trade on the stock exchange, just like stock trading, according to the real-time market price, following the principle of price priority and time priority.
