1. Bidding transaction: This is the most common transaction method and follows the principle of price priority and time priority. Investors can buy and sell through the trading platform of brokers during the trading day and trade at market prices.

2. After-hours fixed-price trading: This is a special trading method introduced by the Science and Technology Innovation Board. After the closing of call auction, the trading system of the exchange will match the closing price declaration in chronological order, and the transaction will be made at the closing price of the day. This method can meet the needs of investors to trade at a certain price outside the bidding period, and is also conducive to reducing the impact of large-value transactions that passively track the closing price on the intraday trading price.

3. Block trading: Also known as block trading, it means that a single securities transaction reaches the prescribed minimum amount, the buyer and the seller reach an agreement through agreement, and the transaction is confirmed by the exchange. This trading method is suitable for the trading of large stocks and can meet the trading needs of large amounts of funds.
