2. Transaction method

2.1. Matching method

• Periodic order matching: A trading method made on the basis of matching buy and sell orders of securities at a specified time. The principles of price determination are as follows:

+ The exercise price reaching the largest trading volume

+ If there are many prices that satisfy the above conditions, the price that is the same or closest to the execution price of the last matching order will be selected.

• Continuous order matching: A trading method performed on the basis of matching buy and sell orders for securities as soon as the orders are entered into the trading system.

2.2. Agreement method:

A transaction method in which members agree with each other on trading conditions.

3. Order matching principle

• Price priority:

+ Orders to buy at a higher price will be executed first.

+ Sell orders at lower prices are executed first.

• Time priority:

In case buy orders or sell orders have the same price, orders entered into the trading system first have priority for execution.

4. Transaction unit

• For even lots: 100 shares/ETF certificates/bonds.
• Put-through trading volume: from 5,000 shares/ETF certificates and from 01 for bond put-through transactions. There is no regulation on trading units for put-through transactions in stocks and ETF certificates.
• The odd-lot trading unit with volume from 01 to 99 shares, ETF certificates is executed by both continuous order matching and put-through methods.
• Put-through and odd-lot trading are not allowed on the first trading day of newly listed shares or the day of resuming trading after being suspended for 25 days until a closing price is determined.

5. Transaction quote unit

• Stock order matching transaction: 100 dong
• Stock put-through transaction: 01 dong
• Trading ETF certificates: 01 VND
• For put-through and bond transactions: 01 VND

6. Price Range

• For stocks: ± 10% of the reference price.
• For stocks, ETF certificates trading on the first day or the first day of trading again after being suspended from trading for more than 25 days is ± 30% of the reference price.
• In case of paying dividend/bonus equal to the number of treasury shares to existing shareholders on the ex-dividend date, it is ± 30% of the reference price.
• For bonds: not regulated.

7. Trading orders

• Limit order (LO)

+ An order to buy or sell a security at a specified price or better. A better price is a price higher than the specified price for a sell order and a price lower than the specified price for a buy order.
+ Valid from the time of entry into the trading system until the end of the periodic closing session or until the order is cancelled.
+ LO orders are allowed to enter the trading system in continuous order matching sessions and periodic order matching sessions.

• Market orders can only be entered into the trading system during a continuous order matching session:

+ Market limit order (abbreviated as MTL): An order to buy at the lowest ask price or sell order at the highest buy price, the order will be canceled when there is no corresponding limit order at the time of entry. trading system, the rest of orders will be converted into limit orders.
+ A market order that is completely matched or canceled (for short, MOK) is a market order that, if not fully executed, will be canceled on the trading system after being entered.
+ Market order to match and cancel (MAK for short) is a market order that can be executed in whole or in part, the rest of the order will be canceled immediately after the order is matched.

• Trading order at the closing price (ATC ):

- The volume of the ATC order of the buyer (or the seller) is added to the volume of the buyer (or the seller) at each price to determine the trading volume at each price during periodic order matching.

- ATC orders take precedence over limit orders while allocating matched orders.

- If in the periodic order matching session to determine the closing price, there are only ATC orders on both sides of the order book, the order matching price is determined as follows:

+ Equal to the latest exercise price if the total volume of buy orders is equal to the total volume of sell orders;

+ Equal to the latest exercise price plus one (01) quote unit if the total buying volume is greater than the total selling volume;

+ Equal to the latest exercise price minus one ( 01 ) quote unit if the total buying volume is less than the total selling volume.

- ATC orders can only be entered into the system during the closing periodic order matching session. After the time of order matching, the order that is not executed or the rest of the order that is not executed will be automatically canceled

• After-hours order matching (PLO)

+ A PLO order is an order to buy or sell securities at the closing price after the end of the closing periodic order matching session.

+ PLO orders are only entered into the system during the after-hours trading session.

+ The PLO order is matched as soon as it is entered into the system if there is a pending reciprocal order. The strike price is the closing price of the trading day.

+ In the event that in the continuous order matching session and the periodic order matching session, the order execution price cannot be determined, the PLO order will not be entered into the system.

- At the end of the after hours trading session, PLO orders that are not executed or the rest of the orders that are not fully executed will be automatically canceled.

8. Edit/Cancel orders

• Price/volume correction, trading order cancellation is only valid for the original unexecuted order or the rest of the unexecuted order.
• In the continuous order matching session: limit orders are allowed to correct price, volume and cancel orders during the trading time. The order of priority of the command after editing is determined as follows:
• Order precedence remains unchanged if only volume reduction is made.
• The order of priority is calculated from the time the correction order is entered into the trading system for the cases of volume correction and/or price correction.
• During the periodic order matching session to determine the closing price (ATC): it is not allowed to modify or cancel LO and ATC orders (including LO orders transferred from the continuous order matching session).
• The PLO order is not allowed to be modified or canceled.
