1. Trading Hours:

 2. Order Matching Methods:

• Continuous Matching:
  A trading method whereby buy and sell orders are matched immediately upon entry into the trading system.
• Negotiated (Put-through) Transactions:
  A trading method in which trading members mutually agree on the terms and conditions of the transaction.

3. Order Matching Principles

Price Priority:

• Buy orders with higher prices are executed before those with lower prices.
• Sell orders with lower prices are executed before those with higher prices.

Time Priority:

• Where buy or sell orders have the same price, the order entered earlier into the trading system shall receive execution priority.

4. Trading Unit

Standard lot: 100 shares.

Odd-lot transactions with volumes from 01 to 99 shares may be executed through continuous matching or negotiated transactions.

No specific trading unit requirement applies to negotiated transactions.

Negotiated transactions and odd-lot transactions are not permitted on the first trading day of newly listed shares or on the first trading day after trading resumes following a suspension of 25 days, until a reference price has been established based on the results of continuous order matching.

5. Price Quotation Unit (Tick Size)

Tick size for shares: VND 100.

No tick size requirement applies to bonds and negotiated transactions.

6. Price Fluctuation Limit

Shares: ± 15%.

For shares newly registered for trading on their first trading day, and shares that have not recorded any transactions for 25 consecutive trading sessions, the price fluctuation limit on the first day of trading or the first day of resumed trading shall be ±40% compared to the reference price.

7. Reference Price:

The reference price is determined as the weighted average price of transactions executed through the continuous matching method during the most recent preceding trading day.

8. Order Types:

The applicable trading order is the Limit Order (LO). A Limit Order (LO) remains valid from the time it is entered into the trading registration system until it is cancelled or until the end of the trading session.

9. Order Amendment and Cancellation During the Trading Session

Order amendments (price or quantity) and cancellations are only applicable to orders that have not yet been executed or to the unfilled portion of partially executed orders.

• In case of an increase in order quantity:
  The order’s priority will be recalculated from the time the amended order is entered into the trading system.

• In case of a decrease in order quantity: The original order priority remains unchanged.
