Market Order vs Limit Order: Key Differences Explained

What is Market Order?

A market order is an order to purchase or sell a security at the best price offered in the market. A market order is primarily an order for execution, not for pricing.

When you make a market order, your broker matches it with the best buy or sell order in the market at that point in time. If there is adequate liquidity, the order is normally executed in seconds within market hours.

Advantages of a Market Order

Here are the key advantages of a market order to consider:

• Provides a high probability of immediate execution at the best available price in the market.
• Best for liquid stocks that have large trading volumes and minimal price fluctuations.
• It is easy to implement for most investors.
• Enables investors to get into or out of a position fast, where the speed of order execution is more essential than the exact price.

Limitations of a Market Order

Here are some key disadvantages of a market order:

• The execution price is not guaranteed.
• Prices may change rapidly during volatile market conditions.
• Large orders may be executed at multiple price levels if liquidity is limited.

What is Limit Order?

A limit order enables you to specify the maximum price you are willing to pay when you buy or the minimum price you will accept when you sell. A limit order differs from a market order in that it prioritises price above immediate execution.

The order will only execute if the market reaches your specified limit price or a more favourable price. If the price is never reached, the order may remain unexecuted until it expires or is cancelled.

Advantages of a Limit Order

Here are the key advantages of a limit order to consider:

• With a limit order, you have more control over the price at which your trade is executed.
• It helps avoid paying more than your preferred purchase price or selling below your desired price.
• It works well when the market is volatile, and prices can change swiftly.
• It is appropriate for traders who wish to enter or exit a position at a particular price as part of their trading plan.

Limitations of a Limit Order

Here are some key disadvantages of a limit order:

• No certainty of order execution.
• The market can move away from the quoted price.
• The order can be completed in parts in the case of insufficient quantities.

Market Order vs Limit Order: Key Differences

Although both order types are used to buy or sell securities, they differ significantly in how they prioritise execution and pricing.

When Should You Use a Market Order?

When you want to get the trade executed quickly rather than at a certain price, it is best to use market orders.

Markets orders are appropriate in several situations, such as when:

• Trading highly liquid stocks with narrow bid-ask spreads
• Trading relatively small quantities (buying or selling)
• Quickly closing out a trade in a volatile market 
• Investing in long-term investments when small price fluctuations are unlikely to make a substantial difference to the result of the investment

Market orders may not be appropriate for lightly traded assets or during periods of high price volatility when execution prices may differ from expectations.

When Should You Use a Limit Order?

If you wish to have more control over the price at which a trade is executed, a limit order is suitable.

You should consider using a limit order if:

• Trading stocks with higher bid-ask spreads
• Buying after a price correction to the desired level
• Selling only when you have reached your goal price
• Trading in a volatile market
• Executing large orders where price fluctuations can impact the total transaction value

Limit orders provide price certainty; however, there is always a chance the market may never hit the price you set.

Slippage, Liquidity and Execution Risk

To compare a market order to a limit order, you also need to understand slippage and liquidity.

• Slippage is the discrepancy between the price you want your order to execute at and the price it actually executes at. This is often the case with market orders, because prices move before the order is completed.
• Liquidity means the capacity to buy or sell a security without causing a major change in the price of that security. Stocks that have a higher trading volume tend to have less slippage, as there are more buyers and sellers in the market.
• Execution risk differs between the two order types. With a market order, there is relatively little risk of execution because the order is filled most of the time instantly. However, there is a stronger possibility of price volatility.

With a limit order, the price is predetermined; however, execution risk is higher because the market may never reach the specified price.

Examples of Market and Limit Orders

The following examples show how market and limit orders work in different situations.

Example of a Market Order

Suppose a stock is at present trading at ₹600. When you put in a market order to buy 50 shares, the order is completed at the best (lowest) selling prices in the order book. If prices move while the order is being processed, the final execution price may be slightly different from the last traded price.

Example of a Limit Order

For instance, if a stock is now trading at ₹520 and you want to buy it only if it falls to ₹500, you can place a buy limit order at ₹500. The order will be carried out only if sellers are willing to sell at ₹500 or below.

Which Order Type is Better for Beginners?

No single order type is ideal for every trader and all market conditions. The decision depends on the investment goal, risk tolerance level, and the type of security exchanged.

Market orders can be useful for new traders buying or selling liquid stocks who want their orders filled quickly and are comfortable with minor price fluctuations.

In comparison, limit orders can be more acceptable for investors who desire greater control over the execution price or are trading during periods of high market volatility. You need to understand how each order type functions and choose between certainty of execution and certainty of price before you place any order. 

Conclusion

Knowing the difference between a market order and a limit order is key to making informed trading decisions. While market orders are executed immediately, limit orders allow traders to choose the price at which the transaction is executed. Which one you should use depends on your trading goals, the market conditions at the time, and the level of price certainty you need. Understanding how each order works enables you to choose the one that best suits your investment strategy.
