3. Types of Orders	ATO (At The Opening) / ATC (At The Closing): These are orders to buy/sell securities at the opening (or closing) price. These orders do not specify a price; instead, they are marked as ATO/ATC. These orders are prioritized over LO (Limit Order) during the matching process and are automatically canceled if not matched.
	LO (Limit Order): This is an order with a specified price, to buy/sell securities at a determined price or better. The order remains valid until the end of the trading day or until it is canceled.
	MP (Market Order): This is an order to buy at the lowest available selling price or to sell at the highest available buying price. It will be canceled if there are no corresponding limit orders at the time the order is entered into the trading system. Any remaining unexecuted portion of the order will be converted into a limit order.	MTL (Market-to-Limit Order): This is an order to buy at the lowest available selling price or to sell at the highest available buying price. It will be canceled if there are no corresponding limit orders at the time the order is entered into the trading system. Any remaining unexecuted portion of the order will be converted into a limit order. MOK (Market Order - Fill or Kill): This is a market order that, if not fully executed, is immediately canceled on the trading system after being entered. It is a market order; if not fully executed, it will be canceled on the trading system immediately after being entered. MAK (Market Order - Fill and Kill): This is a market order that can be executed fully or partially, with the remaining portion of the order being canceled immediately after matching. PLO (Post-Limit Order - This is an order to buy or sell securities at the closing price after the closing periodic order matching session ends): PLO orders are matched immediately upon being entered into the system if there are corresponding orders waiting. The execution price is the closing price of the trading day. If the closing price cannot be determined during the continuous matching session or the closing periodic matching session, the PLO order will not be accepted into the system. At the end of the post-market trading session, any unexecuted PLO orders or remaining portions of the orders will be automatically canceled.
4. Order Matching Principles	Price Priority: Orders with better prices (higher for buy orders, lower for sell orders) are prioritized for matching. Time Priority: If multiple orders have the same price, the order entered first into the system is prioritized.
5. Reference Price	Reference Price is the closing price of the stocks or fund certificates on the previous trading day. Reference Price of Covered Warrant (CW) = Issue Price of CW x (Reference Price of Underlying Stock on the First Trading Day of CW/ Reference Price of Underlying Stock on the CW Issuance Annoucement) x (Conversion Ratio on CW Issuance Annoucement Date/ Conversion Ratio on the First Trading Day of CW)		This is the weighted average price of the execution prices according to the continuous matching method on the previous trading day.
6. Price volatility range	a. Normal trading days: - Price fluctuation Limit: ±7% - Ceiling price = Reference Price + 7% - Floor price = Reference Price – 7% b. On the first trading day: - The reference price is proposed by the listed organization. - Price fluctuation Limit: ±20%. - Ceiling price = Reference price + 20% - Floor price = Reference price – 20% * Negotiation trading is not allowed on the first trading day c. Resumes trading after a suspension of 25 sessions: - Price fluctuation range: ±20% compared to the reference price determined by the Stock Exchange.	a. Normal trading days: ±10% - Ceiling price = Reference price + 10% - Floor price = Reference price – 10% b. On the first trading day: - The reference price for CP/CCQ on the first trading day is proposed by the listed organization. - Price fluctuation range: ±30% c. Resumes trading after a suspension of 25 sessions: - Price fluctuation range: ±30% compared to the reference price determined by the Stock Exchange.	a. Normal trading days: ±15% - Ceiling price = Reference price + 15% - Floor price = Reference price – 15% b.

Stocks resuming trading after a halt of more than 25 sessions: - Price fluctuation range: ±40% compared to the reference price determined by the Stock Exchange.
	The method of placing orders for stocks/convertible bonds on the first trading day or resuming trading after being halted for more than 25 sessions is the same as for listed stocks (negotiation transactions and odd-lot transactions are not allowed until the reference price of the stock is determined)
	d. Covered Warrants: - Ceiling price = Reference price of the Warrant - (Ceiling price of the Underlying Stock - Reference Price of the Underlying Stock) x 1/Conversion rate. - Floor price = Reference Price of the Warrant - (Reference Price of the Underlying Stock - Floor Price of the Underlying Stock) x 1/Conversion rate.

13. General Regulations	Investors are allowed to open multiple securities trading accounts, but only one account per securities company is allowed. Investors can place buy and sell orders for the same security during continuous matching sessions but are not allowed to do so during periodic sessions, except when the investor has already placed a buy or sell order during the previous continuous trading session that has not been matched and is still valid. In such cases, the investor can place a sell or buy order for the same security during the periodic matching session. It is not allowed to use accounts of the same investor opened at different securities companies to conduct opposite transactions for the same security on the same day. Investors must ensure they have sufficient securities when placing sell orders and sufficient funds when placing buy orders. Orders that are partially matched or not yet matched and not canceled during the morning trading session will be automatically transferred to the afternoon session and continue to participate in matching. Foreign investors can only purchase a maximum of 49% of the total listed shares/ETFs, and a maximum of 30% of the total listed bank shares or according to other specific ratios as regulated by each company and permitted by law. Trading fees will be calculated on each matched deal and rounded to the nearest unit. Investors can see more details about other regulations in the Trading Regulations issued by the Stock Exchange.
