Meritz Securities experienced a malfunction in its mobile trading system (MTS), causing inconvenience for investors.
 
According to the financial investment industry, shortly after the market opened at 9 a.m. on June 15, there was a login issue with the Meritz Securities MTS that lasted approximately 15 minutes. As a result, investors faced difficulties with currency exchanges and stock trading. Complaints surfaced on online forums, with users reporting that even while using the latest version of the app, they received prompts for updates.
 
A representative from Meritz Securities stated, "We have identified the issue as a simple login delay affecting some customers for a few seconds."
 
This incident follows a series of technical problems at Meritz Securities. In April, the company reported three separate system errors. On April 1, trading was delayed for about five minutes before the regular market opened, and on April 9, there were login issues and trading delays for approximately 30 minutes after the market closed in both the home trading system (HTS) and MTS.
 
Additionally, on April 29, MTS experienced a login error lasting about 50 minutes. Although the issue stemmed from a server error related to simplified authentication, transactions using joint authentication certificates proceeded normally for existing customers, while some new login users experienced delays that hindered their trading activities.
