Limit Orders vs Market Orders

When you place a trade on an exchange, the order type you choose determines how and whether it fills. The two foundational types are the market order and the limit order. Knowing the difference protects you from surprise fills and slippage.

Market Orders

A market order buys or sells immediately at the best available price. It prioritizes speed over price. You are nearly guaranteed a fill — but you accept whatever the market is offering, which can mean slippage on illiquid assets.

Limit Orders

A limit order sets a specific price. A buy limit only fills at your price or lower; a sell limit only fills at your price or higher. You control the price, but the order may not fill if the market never reaches it.

When to Use Each

• Use a market order when you want certainty of execution and the asset is liquid enough that slippage will be small.
• Use a limit order when you want a specific price, can wait, or are trading an illiquid token where market orders might move the price against you.

A Simple Example

A token trades at $10. A market buy fills immediately, but slippage might put your average at $10.30. A limit buy at $10.00 only fills if the price reaches $10.00 — it may fill instantly, partially, or not at all.

Common Misunderstanding

A limit order is not free insurance. If you place a limit sell far above the current price, you may wait forever. And a limit order that is close to the market can still miss if price moves away and never returns.
