Beginner principle: Understand the mechanics and risks before buying. Knowing orders, settlement, and costs matters more than finding a hot tip.
Regular trading runs 9:00–13:30
TWSE regular-session matching runs from 9:00 to 13:30 on trading days, while ordinary orders can be entered from 8:30.
Pre-open information is not a guaranteed execution price
The 8:30–9:00 period includes order entry and indicative auction information. The opening price is determined by auction rules.
Odd lots have a separate matching process
Intraday odd-lot orders are accepted from 9:00 to 13:30, with matching beginning at 9:10 and currently occurring every five seconds by auction.
There are after-hours sessions too
After-hours fixed-price orders run 14:00–14:30, while after-hours odd-lot orders run 13:40–14:30 under separate rules.
What to learn next
- No account yet: start with the account-opening guide
- Planning to buy ETFs: learn fund structure and premiums/discounts
- Considering leverage: first understand margin and stock-backed borrowing risks
