1.8. Market Orders and Limit Orders
Lesson objective
Distinguish the two most basic order types.
A market order seeks immediate execution at the best available price. It prioritizes the probability of execution but does not guarantee the final price, especially in assets with low liquidity or high volatility.
A limit order sets a maximum purchase price or minimum sale price. It offers greater price control but may not execute if the market never reaches that level.
Stop and stop-limit orders involve additional uses and risks. Beginners should understand market and limit orders before using more complex instructions.
Simple example
A stock displays $20.00, but a market order might execute at $20.08 if the price moves or there are not enough shares available at $20.00.
Execution certainty vs. price control
| Order | Main advantage | Main risk | |---|---|---| | Market | Prioritizes execution | Execution price is not guaranteed | | Limit buy | Sets maximum purchase price | May never execute | | Limit sell | Sets minimum sale price | May never execute |
A buy limit at $50 can execute at $50 or lower. A sell limit at $50 can execute at $50 or higher.
Fast-market example
The last trade is $25.00 but the best ask jumps to $25.40. A market buy may execute near the available ask. A $25.10 limit buy protects your maximum price but may remain unfilled.
No order type guarantees both immediate execution and an exact price.
Essential terms
| Term | Practical meaning | |---|---| | Market order | Seeks quick execution without guaranteeing price. | | Limit order | Executes only at the specified price or better. | | Time in force | How long an order remains active. |
What you should remember
- Execution and price are different objectives.
- A limit order may remain unfilled.
Practice
Describe when you would prioritize execution and when you would prioritize price.
