The working hours of a securities company are the same as the trading hours of the stock market, from Monday to Friday: 8: 30-1:30, 13: 00- 16: 40, with public holidays and holidays as rest time and no work.
The business hours of most securities companies are from 9: 00 a.m. to 4: 00 p.m., so it's best to call for advice before handling business. It should be noted that Saturday and Sunday are closed, and legal holidays are also closed.
