Market orders execute trades instantly at the best available current price for financial assets. This fundamental trading tool "consumes" existing limit orders in the order book, creating potential price discrepancies known as slippage.
Key Differences: Market Orders vs. Limit Orders
| Feature | Market Orders | Limit Orders |
|---|---|---|
| Pricing | Current market price | Pre-set price or better |
| Execution | Immediate | Only when price target met |
| Control | Low (price varies) | High (fixed parameters) |
| Best For | Urgent transactions | Price-sensitive strategies |

How Market Orders Work in Practice
- Order Matching: Your market buy order fills at the lowest available ask price in the order book
- Partial Fills: Large orders may execute across multiple price levels
Slippage Occurs: When execution price differs from expected price due to:
- Low liquidity
- High volatility
- Large order size
Example: Buying 500 BNB might execute across prices from $371.40 to $373.20 if liquidity is insufficient at the best price.

- Trading highly liquid assets (BTC, ETH)
- Time-sensitive transactions
