Beginner principle: Understand the mechanics and risks before buying. Knowing orders, settlement, and costs matters more than finding a hot tip.
The last price is a completed trade
The latest trade is a historical execution, not a guarantee that your next order will receive the same price.
The five-level book shows unexecuted orders
TWSE publishes leading outstanding bid and offer prices and quantities. These orders can execute, change, or be canceled.
Large displayed size is not guaranteed support or resistance
Orders can be canceled or consumed by larger market orders, so visible depth should not be treated as a prediction.
Use official market information for verification
TWSE's market information service provides index, stock, order-book, odd-lot, and market-announcement data.
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
Primary / official sources
