The Market-On-Close Order refers to a stock market order whereby a particular security is traded very close to its last trading price on that particular day. Such an order is either executed at the same time when the market closes or just after that.

The primary objective of the traders is to buy or sell stocks, futures, or options at the price point nearest to the market’s closing price. Thus, it facilitates the investors and traders to execute trading strategies in foreign exchange markets with different time zones or exit a position at the closing price of the day.

Key Takeaways

  • The market-on-close order refers to a trading strategy for buying or selling a particular security, future, or option immediately as the market closes or right after it at the closing price of that trading day.
  • A market-on-close order facilitates the traders to execute security trading in different financial markets or foreign exchanges, having independent time zones.
  • Market-on-close (MOC) orders are particularly useful for investors looking to avoid potential price fluctuations that can occur during the trading session.

How Does Market-On-Close Order (MOC) Work?

The market-on-close (MOC) order is a stock market trading approach to buying or selling a security, future, or option at its closing market price for the day. This order only stands active at the end of the relevant trading day. Indeed, it works as a normal market order after that. It is a common trading strategy adopted by intraday traders to conveniently exit the market without hustling at the closing hour. Moreover, it is usually done to avoid the risk of overnight price fluctuations in the financial market.

To make an MOC, the investor needs to opt for the BUY or SELL option after entering the respective stock’s ticker symbol. It is necessary to enter the correct size or number of shares for which the order is to be executed. Another critical step is to click on the market-on-close (MOC) option, which will be found in the order type’s dropdown menu. Finally, the user needs to submit the market-on-close order, which will be exercised as the market closes.


Let us understand how the market-on-close order works for effectively trading securities in reality with the help of the below examples:

Example #1

Suppose Anne is a finance graduate, and she has a keen knowledge of the stock market. She holds 1500 shares of XYZ Pharma Co., on which she has already made 15% returns in a week. However, the news of the consequent failing clinical trials of the company, which would cover the next day’s news and media, made her place a market-on-close order to exit her position. As the MOC became active, she sold all her shares at a profit of 11% from the purchase price.

Example #2

Say George is an active investor who keeps up with the company’s news and financial reports to gain a trading advantage. He is closely following the news of PQ Fintech, which is going to launch new digital features to provide seamless financial services to its clients. He anticipated the company’s stock prices would flare up with this launch. Therefore, just a day before the company made this announcement, he made a market-on-close order to buy 500 shares of PQ Fintech at the closing price of the day. The execution price per share was $57; however, as the company announced its digital initiative, the stock prices reached $68, I.e., trading at $11 per share profit.

Advantages And Disadvantages

The market-on-close order is a beneficial strategy for traders, investors, and brokers to effectively trade in the financial markets. However, along with the various benefits, it has particular potential drawbacks, as discussed below:

#1 – Advantages

  • Protects from overnight price volatility: The traders often adopt MOC to mitigate the risk of an overnight price fluctuation of the relevant stocks, futures, or options when a massive news story is expected to be released or an earnings call is scheduled the next day.
  • Facilitates trading in different time zones: The investors who trade in different foreign exchanges or stock markets functioning in varying time zones need to use MOC to exit the trade as the market closes.
  • Offers automatic execution: Since the MOC executes the trade at the closing price immediately as the market closes, the traders don’t need to keep an eye on the market prices or the clock every time.
  • Ensures execution certainty: The market-on-close order also helps the investors to buy or sell securities when they know they won’t be there to execute the market order when the market closes.

#2 – Disadvantages

  • Uncertain execution price: The foremost limitation of this strategy is that the traders need to be made aware of the final price. Also, they have no control over the same after a designated time.
  • Closing price volatility risk: The financial markets are uncertain, and the stock prices may significantly fluctuate at the closing time, which increases the risk of selling at a lower price or buying at a higher price than anticipated by the investor.
  • Can adversely affect the market: If several traders perform the same trading action for a particular security through MOC, then it may impact the market stability and the stock prices.
  • Chances of poor execution: There is a possibility that the high volume of trade through market-on-close orders at the end of a trading day can result in pending requests.

Frequently Asked Questions (FAQs)

1. What is the difference between market-on-close and market-on-open orders?

The market-on-close order and the market-on-open (MOO) orders are similar trading strategies. While the MOC enables the trading of security at the end of a trading day or shortly after the market closes, the MOO facilitates the buying or selling of the security right at the beginning of the trading day or immediately after the market opens.

2. Is a MOC (market-on-close order) buy or sell?

The market-on-close order allows one to buy or sell a particular security at that trading day’s final price based on the investor’s strategy.

3. Is market order the same as market-on-close order?

The market order and the market-on-close order differ in the following ways:
1. The former is a normal trading order executed promptly as the trader finds the best market price for the security. Meanwhile, the latter is a pre-set order to execute a trade at the closing price or the price nearest to it at the end of a trading day.
2. In a market order, the execution price is uncertain, but in MOC, the closing price is the execution price.
3. Once an MOC is active, it turns into a market order.
