  1. Overnight Tradable List

This list is for reference only and shall be subject to what is available on the Tiger app.

  1. Important Information for Full-Time Orders:

For full-time orders, any unfilled orders must be transferred to the next trading session. For example, at the end of the Overnight Trading Session, any unfilled orders need to be moved to the MKT+Pre/Post-MKT sessions, while unfilled GTC (Good-Till-Canceled) orders must be transferred to the next day’s Overnight Trading Session. This process may result in a brief loss of trading time, such as between 20:00:00 and 20:00:10 or between 03:59:40 and 04:00:00 during the Overnight Trading Session.
