Market Order vs. Limit Order: Which should investors use?

One of the first decisions investors may face when placing a trade is whether to use a market order or a limit order. The choice often comes down to whether completing the trade quickly or having greater control over the price is more important for that particular transaction.

A market order generally aims to buy or sell a security as soon as possible at the best available market price. A limit order allows the investor to choose a specified limit price, meaning the trade may only execute at that price or better. While a market order typically prioritizes execution, a limit order prioritizes price control.

Understanding the difference between these order types may help investors compare how each works under different market conditions, including periods of higher volatility or wider bid-ask spreads.

Market order vs limit order: the quick answer

The primary difference in the market order vs limit order comparison is what each order type prioritizes.

A market order instructs a brokerage to buy or sell a security as soon as possible at the best available current market price. Because the order seeks immediate execution, the final price may differ from the quoted price that appeared when the order was entered.

A limit order instructs the brokerage to execute the trade only at a specified price or better. When buying, the investor sets the maximum price they are willing to pay. When selling, the investor sets the minimum price they are willing to accept.

In simple terms:

• A market order generally prioritizes execution.

• A limit order generally prioritizes price control.

If completing the trade quickly is the primary objective, a market order may be considered. If receiving or paying a particular price is more important, a limit order may be considered instead.

What is a market order?

A market order is an instruction to buy or sell a security as soon as possible at the best available market price. Unlike a limit order, it does not allow the investor to set a maximum purchase price when buying or a minimum sale price when selling.

Because the market is constantly changing, the displayed current price before an order is submitted may differ from the final fill price. This difference can occur when prices move quickly, trading volume changes, or the bid-ask spread widens.

For example, imagine a stock is quoted at approximately $20.00. If an investor places a market order to buy a stock, the order may be executed immediately, but the final execution price could be slightly above or below $20.00, depending on available orders at that moment.

Market orders are commonly associated with highly liquid securities traded during regular market hours, where many buyers and sellers are actively participating. Even in these situations, however, the execution price is determined by available market liquidity at the time the order reaches the stock exchange.

What is a limit order?

A limit order is an instruction to buy or sell a security only at a specific price or better. Unlike a market order, which prioritizes execution speed, a limit order gives the investor more control over the execution price.

When placing a limit order to buy, the investor sets the maximum price they are willing to pay. When placing a sell limit order, the investor sets the minimum price they are willing to accept.

For example, if a stock is trading around $20.00 and an investor places a buy limit order at $19.75, the order may execute if the stock price reaches $19.75 or lower. If the market never reaches that level, the order may remain open or expire depending on the selected duration.

A limit order can help investors avoid paying more than their specified price when buying or accepting less than their desired price when selling. However, the trade-off is that execution is not guaranteed. The market must reach the selected limit price and have enough available buyers or sellers for the order to be filled.

Partial fills

If only some of the shares are available at your limit price, the order may fill partially, leaving the remainder open until the duration expires or you cancel it.

Limit orders can be used with different order durations, including a good till canceled (GTC) limit order, which may remain active until it is filled or cancelled according to the brokerage's rules.

Key differences between market and limit orders

The difference between a market order vs limit order comes down to the balance between execution and price control.

Market orders may be useful when completing a transaction quickly matters more than receiving a specific price. A limit order may be useful when an investor wants to control the maximum purchase price or minimum selling price.

For example, during a period of rapid price movement, a market order could execute at a significantly different price than the quote displayed before submission. A limit order may help manage that possibility by setting a specific price, but the trade may not occur if the market moves away from the selected level.

The choice often depends on the circumstances of the trade, including liquidity, volatility, bid-ask spreads, and whether execution speed or price control has greater importance for that transaction.

When might a market order make sense?

A market order may be considered in situations where the investor places greater importance on completing the trade than on receiving a specific price.

Examples of circumstances where a market order may be used include:

• The investor wants the order completed quickly.

• The security has high trading volume and active buyers and sellers.

• The trade occurs during regular trading hours.

• The investor understands that the final price may differ from the displayed quote.

• The difference between the quoted price and final execution price may have limited impact on the transaction.

For example, an investor purchasing a small number of shares in a widely traded ETF during regular market hours may choose a market order if completing the transaction promptly is more important than setting an exact purchase price.

However, market orders may have different outcomes depending on market conditions. Securities with lower trading volume, wider bid-ask spreads, or rapid price fluctuations may experience greater differences between the displayed price and the final execution price.

A market order does not guarantee a specific fill price. Instead, it allows the trade to execute against available buyers or sellers in the market.

When might a limit order make sense?

A limit order may be considered when price control has greater importance than immediate execution.

Examples of situations where a limit order may be used include:

• The investor wants to set a maximum purchase price.

• The investor wants to set a minimum sale price.

• The security has a wide bid-ask spread.

• The market is experiencing significant price changes.

• The investor is comfortable waiting for the market to reach a specific price.

For example, if an investor wants to purchase a stock but does not want to pay more than $25.00 per share, they could place a buy limit order at $25.00. If the stock reaches that price or lower, the order may execute. If the stock price never reaches that level, the order may remain unfilled.

Similarly, an investor looking to sell stocks at a minimum acceptable price may use a sell limit order to specify the lowest price they are willing to accept.

A limit order can help provide control over the price of a transaction, but it comes with the possibility that the trade may not happen. The market must reach the specified limit price and available buyers or sellers must exist at that level for execution to occur.

How to choose between a market order and a limit order

Choosing between a market order vs limit order can depend on the goal of the trade, market conditions, and whether execution speed or price control matters more for that transaction.

Investors may consider the following factors:

• Speed vs. price control: A market order may be considered when completing a trade quickly matters more than receiving a specific price. A limit order may be considered when the investor wants to set a maximum purchase price or minimum sale price.

• Liquidity: Securities with many buyers and sellers may have tighter bid-ask spreads. Less liquid securities may have wider spreads or fewer available orders.

• Market movement: During periods of rapid price changes, a market order may execute at a different price than the displayed quote. A limit order may provide more control but may not fill.

• Execution certainty: A market order generally focuses on completing the trade, while a limit order requires the market to reach the selected price.

In simple terms, a market order may be considered when execution is the priority, while a limit order may be considered when price control is the priority.

Conclusion: choosing the right order type

Market orders and limit orders serve different purposes in stock trading. A market order may be useful when completing a trade quickly is the priority, while a limit order may be useful when controlling the transaction price is more important.

Before choosing an order type, investors can consider liquidity, volatility, bid-ask spreads, market conditions, and whether they are comfortable with immediate execution or the possibility that an order may not fill.
