Pre-opening session details (09:00-09:30)

The pre-opening bidding period is divided into four stages:

1. Input the buy and sell order period (09:00-09:15)

   • Allow input of bidding orders and limit bidding orders
   • Modify or cancel orders

2. Pre-market period (09:15-09:20)

   • Accept bid orders and limit orders within a specified range
   • The entered buy and sell orders cannot be modified or canceled

3. Trading session (09:20-09:22)

   • Prohibit inputting, changing, or canceling buy and sell orders
   • Conduct random matching of buy and sell orders

4. Suspension period (after the trading is completed until 09:30)

   • All buy and sell orders and trading activities are suspended
   • Until the morning trading session begins

During the pre-opening period, the system calculates the reference equilibrium price based on the price entered by the investors and automatically matches buy and sell orders during the trading period. Investors can use this time to analyze the market and look for potential trading opportunities.

After-hours session (16:00-16:08/16:10) details

The after-hours trading session is divided into four phases, and its mechanism is the opposite of the pre-opening session.

1. Calculation and announcement of reference price period (16:00-16:01)

   • The exchange calculates and publishes the reference price

2. Enter the buy and sell order period (16:01-16:06)

   • Allow input, cancel, or modify orders

3. Non-cancellable period (16:06-16:08)

   • Only order input is allowed, cancellation or modification is prohibited

4. Random closing period (16:08-16:10)

   • Allow order input, but prohibit cancellation or modification
   • Randomly end the transaction within these two minutes

The reference price for the after-hours trading session is calculated by the exchange based on the data from the last minute of the continuous trading session. The buy and sell order prices entered by investors must be within 5% of the reference price. The system will ultimately select the price with the largest trading volume as the closing price.
