Understanding Limit Orders in Trading
Limit orders allow traders to specify exact price points for buying or selling securities. Unlike market orders that execute immediately at current prices, limit orders only fill when the market reaches your predetermined price level.
Key features of limit orders:
- Set maximum purchase price when buying
- Set minimum sale price when selling
- Only execute if market reaches your limit price
- Include time duration specifications
- Work with whole shares only (not fractional)
How Limit Orders Work: Practical Examples
Let's examine two common scenarios where limit orders prove valuable:
Buy Limit Order Example
Scenario: Stock XYZ trades at $20/share, but you only want to buy if the price drops to $19.
Action: Place a buy limit order at $19 for 100 shares.
Outcome: Your order executes only if:
- Price drops to $19 or lower
- Sufficient shares available at that price
- Within your specified time duration
Sell Limit Order Example
Scenario: You own XYZ shares currently at $49, but want to sell at $50.
Action: Place sell limit order at $50 for 300 shares.
Outcome: Order executes only if:
- Price rises to $50
- Buyers available at that price
- Within your chosen time frame
The Time Component: Order Durations Explained
Every limit order requires selecting a duration - the period your order remains active. Common duration types include:
👉 Day Orders (expire at market close)
👉 Good-Til-Canceled (remain active until filled or manually canceled)
👉 Immediate-or-Cancel (execute immediately or cancel)
👉 Fill-or-Kill (require complete execution or cancel entirely)
Select durations carefully based on your trading strategy and market conditions.
Important Considerations When Using Limit Orders
While powerful tools, limit orders come with limitations:
- No execution guarantees - Your order may never fill if the market doesn't reach your price
- Price matching requirements - Buys require matching ask prices; sells require matching bid prices
- Whole shares only - Cannot be used for fractional share trading
- Market liquidity dependence - Requires sufficient buyers/sellers at your price point
