How to trade stocks when the KRX system is operating

(NLDO)- According to HoSE, the new KRX system only displays information on the three best bid and offer prices during the periodic order matching session.

In order to help investors understand and facilitate securities transactions when applying the Information Technology System (KRX) officially applied from May 5, the Ho Chi Minh City Stock Exchange has introduced an illustrative example in the periodic order matching session.

Accordingly, The information on the three best bid and offer prices displayed is the three best bid and offer prices expected to remain after order matching, along with the expected bid and offer volume remaining after order matching corresponding to those prices (currently displaying information on the three best bid and offer prices of each type of security, along with the bid and offer volume corresponding to the prices currently available on the order book).

HoSE officially operates KRX system from May 5
