 Off-Hours Trading
Off-hours trading is the extra trading period after the closing of the regular trading session. This facility enables investors, especially institutional investors and foreign investors, to adjust their positions. It also serves as a tool for traders to adjust error transactions or cover the transactions executed in the regular session.
Off-hours trading starts from the random closing time until 17:00 hours. Only Put-Through transactions can be recorded on the main board, big lot board and foreign board, as specified in the following rules:
