(NLDO)- The KRX system will be officially put into operation from May 5 at HoSE with some changes compared to before.
On March 13, Vietnam Securities Depository and Clearing Corporation (VSDC) said it had just received a dispatch from the Ho Chi Minh City Stock Exchange announcing a plan to test the entire KRX trading system and is expected to put it into official operation from May 5.
According to this plan, the final comprehensive testing phase (4 weeks) is expected to take place from March 17 to April 11, including system functionality testing on converted data and system conversion simulation.
This is followed by the official deployment preparation phase (12 days), from April 14 to April 20, focusing on functional testing and simulating system conversion on the latest data. The deployment phase is from April 30 to May 4.
VSDC requires members to develop detailed test scenarios based on the framework scenario and submit test result reports to VSDC within 2 days after the end of each phase.
Regarding the new KRX system, the Ho Chi Minh City Stock Exchange (HoSE) said that when it officially operates, there will be new regulations compared to the current ones.
Specifically, ATO/ATC orders will not take precedence over previously entered limit orders when matching orders. ATO/ATC orders will be displayed at a specific price as limit orders, instead of the current "ATO" or "ATC" symbols.
Edit, cancel matching order: Allows to edit price or volume of unexecuted LO order or remaining part of unexecuted order. Edit to decrease volume → does not change priority order. Edit to increase volume or edit price → changes priority order.
Negotiated Transactions: It is not allowed to edit or cancel a negotiated transaction that has been made on the system. Currently, it can be edited by canceling and re-entering.
Foreign investor transactions: Room decreases when foreign investor buy orders are entered into the system. Room increases when: Buy orders are canceled → room increases by the canceled volume. Buy orders are revised to decrease volume → room increases by the decreased volume. Buy offer orders are canceled with domestic investors → room increases immediately after the canceled order is entered.
Odd lot transactions: Executed by periodic order matching method (instead of only continuous order matching and agreement as at present).
Restricted securities trading: Securities subject to restricted trading will be allowed to trade all day using the periodic order matching method, instead of only in the afternoon session as before. This process includes periodic order matching sessions every 15 minutes and a closing order matching session.
Show information of 3 bid/ask prices: Shows the 3 best prices expected to remain after the order is matched. Currently shows information of all orders on the trading order book.
