The Ask Price (also called Offer Price) is the lowest price a seller will accept for a security.
How Asks Appear
In SETS order books, asks form an ascending ladder:
| Ask Level | Price | Quantity |
|---|---|---|
| Best Ask | 100.60p | 3,000 |
| Level 2 | 100.70p | 7,500 |
| Level 3 | 100.80p | 12,000 |
The best ask (100.60p) is where you'd buy if executing a market order immediately. Higher levels show available supply at worse prices.
Terminology Across Markets
| Region | Common Term | Usage |
|---|---|---|
| US | Ask | Standard term |
| UK (historical) | Offer | Traditional usage |
| UK (modern) | Ask/Offer | Both interchangeable |
LSE data feeds may use either term - they mean the same thing.
Trading at the Ask
When you buy shares:
- Market orders execute at current best ask
- You "cross the spread" by accepting seller's price
- Limit orders below the ask join the bid side
The ask represents immediate availability - the price of certainty versus waiting for a better price.
