On the 18th, it was reported that a delay error in orders for Mirae Asset Securities occurred in the pre-market (Pre-Market · 8 a.m. to 8:50 a.m.), and it was due to employee oversight rather than a system issue.
On that morning, due to a trading system (HTS·MTS) error at Mirae Asset Securities, Next Trade (NXT) pre-market transactions were halted for about 10 minutes starting at 8 a.m. After about 10 minutes, new orders began to be processed normally, but some unfulfilled quantities could not be amended or canceled, leading to an outburst of investor dissatisfaction.
Mirae Asset Securities announced around 2 p.m., six hours after the incident, that it had completed measures for delayed orders during the pre-market hours. The market speculated that issues had occurred with the automated order transmission system (SOR) launched by Mirae Asset Securities in line with the opening of the alternative exchange on the 4th of last month.
However, there are claims in the market that this incident was a man-made disaster. An IT industry source familiar with the internal situation at Mirae Asset Securities noted, "I understand that Mirae Asset Securities mistakenly did not perform the SOR initialization in the morning, and this caused problems when connecting to the system linked to the exchange."
This source stated, "They belatedly initialized the SOR but did not initialize the exchange connection system, causing orders to stop, and although they later synchronized both systems, the order information entered earlier was lost, preventing those customers from placing orders for a long time until it was restored."
Mirae Asset Securities had previously experienced issues with delayed order confirmations on the 4th of last month when the alternative exchange was launched.
Meanwhile, Mirae Asset Securities clarified that this incident was not due to employee negligence. A representative from Mirae Asset Securities stated, "We are currently identifying the exact cause of the error," emphasizing, "It is definitely not due to employee oversight."
