What Is a Limit Order?
In plain English
A limit order is an instruction to buy or sell a security at a specified price or better. Buy limit orders execute at or below the limit price; sell limit orders execute at or above it. Unlike market orders, limit orders prioritize price certainty over execution certainty.
How Does a Limit Order Differ From a Market Order?
A market order fills immediately at the best available price, while a limit order only fills at your specified price or better. Limit orders protect you from unfavorable price swings but may not execute if the market never reaches your price. They are especially useful for less liquid securities where spreads are wide.
When Should You Use a Limit Order?
Limit orders are ideal when you have a target entry or exit price and are willing to wait. They are commonly used for volatile stocks, after-hours trading, or large orders where a market order might move the price against you. Many long-term investors also use limit orders to buy on dips.
What Happens If a Limit Order Does Not Fill?
If the market price never reaches your limit, the order expires unfilled. You can set duration conditions — a day order expires at market close, while a good-til-canceled (GTC) order remains open for up to 60–90 days depending on the brokerage. Unfilled orders tie up no capital until executed.
Frequently asked questions
Do limit orders cost more than market orders?
Most brokerages charge the same commission (often $0) for both order types. However, limit orders may result in partial fills on larger orders, which some brokerages could treat as separate transactions for fee purposes.
Can a limit order fill at a better price than specified?
Yes. A limit order sets the worst acceptable price. If the market offers a better price when your order reaches the front of the queue, you receive the improved price. This is called price improvement.
