At the beginning of the market this morning, as the trading volume rushed all at once, a brokerage company had the stock trading system not working properly for more than an hour.

The brokerage company offered to compensate the victims according to regulations, but a serious security problem occurred while access to the trading system was difficult.

[Mr. Kang Mo/Mirae Asset Daewoo user: I haven't been connected for almost two or three hours.

Mirae Asset Daewoo said that it is trying to compensate for customer damage caused by computer failure, saying that it is trying to determine the cause.

As the number of domestic individual investors, symbolized by Donghak ants, has exploded, complaints related to accidents in the trading system of securities companies have increased significantly.

It is pointed out that domestic securities firms, which made close to 6 trillion won in profits last year thanks to the booming stock market, are actually putting their hands on system management.
