Matching time 10:00 am, 10:30 am, 11:00 am, 11:30 am,

12:00 pm, 12:30 pm and 1:00 pm

Order types

  • Market order

    • A market order is an order placed without specifying the buying or selling price.

    • Even though a market order has price priority than other limit orders and is likely to be executed, the order has risk which an investor may buy or sell shares at his/her unexpected higher or lower matching price.

  • Limit order

    • A limit order is an order placed by specifying the price at which the trader seeks to buy or sell shares.

    • Even though an investor placing a limit order can avoid risk of buying/selling shares at unexpected price, an investor cannot buy/sell shares if a matching price is superior than his/her limit order price.

Price limit

  • To prevent too much volatility of stock prices, YSX sets daily price limit for all stocks of listed companies.

  • An upper and a lower limit price of the day is decided based on a level of a base price under the table stipulated in the Enforcement Regulations for Trading Business Regulations. A base price, in general, is the last matching price of a previous working day.

  • In case where a base price is MMK 35,000, an upper limit price becomes MMK 40,000 (MMK +5,000) and a lower limit price becomes MMK 30,000 (MMK -5,000)

(Excepted price limit table)

Matching methods

  • Price priority: The order price that is superior than other orders gets filled first and a market order has the first price priority.

  • Time priority: If the price priority is same, earlier order has priority to get filled first.

  • Call auction methods:

    • For each limit price recorded in the order book, the system calculates the cumulative amounts in each buy and sell order book side.

    • For a market order, each buy/sell market order is placed on the cumulative buy/sell order column of the upper limit price/lowest limit price with the superior price priority than the limit orders.

    • Comparing the totals of each order book side, a matching price is determined in the price allowing the largest number of stocks to be traded. Then, all the stocks are filled at this matching price.

    • If there are two candidate prices to be a matching price, a closer price with the last matching price or a base price becomes a matching price


Placing orders and order matching

  • An investor is able to send his/her orders, through a securities company, to YSX anytime during trading hours and orders are filled if the orders satisfy matching requirement mentioned above.

Confirming order execution

  • After a matching time at 10:00 am,10:30 am,11:00 am,11:30 am, 12:00 pm,12:30 pm or 1:00 pm, an investor receives execution result of his/her orders through a securities company’s execution notice if his/her orders are executed.
