Buying a stock involves more than deciding which company you want to invest in. You also need to decide how you want your trade to be executed.
This is where market orders and limit orders come in.
If you’re learning how to trade stocks in Nigeria, understanding these two order types is an important part of getting comfortable with the stock market. A market order prioritises getting your trade executed at the best available price, while a limit order gives you more control over the price you are willing to accept.
Neither is automatically better than the other. The right choice depends on what you’re trying to achieve, how quickly you want the trade executed, and the conditions in the market.
Let’s break down how both work and when you might use each one.
What Is a Stock Order?
A stock order is an instruction you give to your broker or investment platform to buy or sell shares.
For example, imagine you want to buy 100 shares of a company listed on the Nigerian Exchange (NGX). When placing your order, you need to provide details such as the stock, number of shares and the type of order you want to use.
The two common order types we’ll focus on are:
- Market order: An instruction to buy or sell at the best available price in the market.
- Limit order: An instruction to buy or sell only at a specific price or a better one.
The simplest way to remember the difference is:
Market order = prioritise execution.
Limit order = prioritise price.
This distinction becomes particularly useful when you’re learning how to trade stocks in Nigeria because the price you see on your screen is not necessarily the exact price at which your trade will be executed.
What Is a Market Order?
A market order tells your broker to execute your trade at the best available price in the market.
Suppose a stock is currently trading around ₦50 per share, and you want to buy 100 shares. You place a market order for those shares.
The order will be matched against available sellers. If shares are available at ₦50, some or all of your order may execute around that price. If the available shares are at slightly different prices, your order may be filled at those prices instead.
This means a market order does not guarantee a particular price.
How a Market Order Works
The process is straightforward:
- Select the stock you want to trade.
- Enter the number of shares.
- Choose market order.
- Submit the order.
- Your broker attempts to execute it against available orders.
The actual execution price depends on what is available in the market when your order reaches the market.
Advantages of Market Orders
1. They prioritise execution
If your main goal is to complete the trade, a market order can be useful because it does not require the stock to reach a particular price first.
2. They are simple to use
You don’t need to decide on a specific entry or exit price. You simply instruct your broker to execute at the best available price.
3. They can be useful for liquid stocks
When there are plenty of buyers and sellers, there may be less difference between the displayed price and the price at which your order is executed.
Potential Drawbacks of Market Orders
The biggest consideration is price uncertainty.
The price displayed when you place the order may change before your trade is executed. This can happen because stock prices move as buyers and sellers place orders.
For example, if you see a stock at ₦50 and place a market order, you shouldn’t automatically assume every share will be purchased at exactly ₦50.
This is one reason understanding order types matters when learning how to trade stocks in Nigeria.
Market orders also require extra consideration when dealing with less-liquid stocks or larger orders, where there may not be enough shares available at one price to fill the entire order.
What Is a Limit Order?
A limit order gives you more control over the price at which you’re willing to buy or sell a stock.
If you’re buying, you specify the maximum price you’re willing to pay.
If you’re selling, you specify the minimum price you’re willing to accept.
For example, suppose a stock is currently trading at ₦50, but you only want to buy it at ₦48 or less.
You could place a limit order at ₦48.
Your order will only execute if the market reaches ₦48 or a better price and there are enough shares available to match your order.
How a Limit Order Works
Let’s say you want to buy 100 shares at a maximum of ₦48 per share.
You place a limit buy order:
- Stock: Company XYZ
- Quantity: 100 shares
- Order type: Limit
- Limit price: ₦48
If the stock falls to ₦48 and there are sellers willing to sell at that price, your order may be executed.
If the stock stays at ₦50, your order won’t execute because ₦50 is above your ₦48 limit.
This gives you price control, but there is a trade-off: your order is not guaranteed to be filled.
Advantages of Limit Orders
1. Greater price control
You decide the highest price you’re willing to pay or the lowest price you’re willing to accept.
2. Useful for specific entry or exit prices
If you’ve analysed a stock and have a particular price in mind, a limit order can help you stick to that price instead of accepting whatever price is available.
3. Can help reduce unexpected price differences
Because you’ve specified the price conditions for the trade, you have greater control over the execution price.
Potential Drawbacks of Limit Orders
The main downside is that your trade may never happen.
If you set a buy limit at ₦48 and the stock stays above ₦48, your order may remain unfilled.
The same applies when selling. If you set a sell limit at ₦55 and the stock never reaches that price, the sale won’t happen.
A limit order therefore gives you price certainty without execution certainty.
Market Orders vs. Limit Orders: What’s the Difference?
Here’s a quick comparison:
| Feature | Market Order | Limit Order |
|---|---|---|
| Main priority | Execution | Price |
| Price control | Lower | Higher |
| Execution | At the best available price | At specified price or better |
| Guaranteed execution? | Not necessarily, as liquidity still matters | No |
| Best suited for | Investors prioritising execution | Investors prioritising price |
| Main consideration | Final execution price can vary | Order may remain unfilled |
Another way to think about it:
Market order: “Buy or sell my shares at the best available price.”
Limit order: “Buy or sell my shares only if I can get this price or a better one.”
Understanding this difference is one of the fundamentals of learning how to trade stocks in Nigeria.
When Should Nigerian Investors Use a Market Order?
There isn’t a single rule that says when every investor should use a market order. Your decision should depend on the circumstances of the trade.
A market order may make sense when:
You prioritise getting the trade done
If you’ve decided to buy a stock and are comfortable with the prevailing market price, you may prioritise execution rather than waiting for a particular price.
You’re trading a relatively liquid stock
Stocks with sufficient buying and selling activity may offer more available orders around the current market price.
However, liquidity can vary from stock to stock, so don’t assume every NGX-listed stock will behave the same way.
You don’t have a specific price target
If you’re comfortable with the price available in the market and don’t need to wait for a particular price, a market order can be a straightforward option.
You understand the execution-price risk
Before placing the order, remember that the final execution price can differ from the price you saw when you initiated the trade.
When Should Nigerian Investors Use a Limit Order?
A limit order may be more appropriate when price matters more than immediate execution.
You have a specific buying price
Suppose you’ve researched a stock and decided you’re comfortable buying it at ₦100 but don’t want to pay more than that.
A limit order lets you specify ₦100 as your maximum purchase price.
You want to set a minimum selling price
If you’re selling shares and have decided you won’t accept less than ₦120, you could use a limit sell order at ₦120.
You’re willing to wait
Limit orders work best when you’re comfortable with the possibility that your trade won’t execute immediately, or at all.
You want more control over your trading decisions
A limit order can help you define your price before entering the trade instead of making a decision based on whatever price is available at the moment.
For investors figuring out how to trade stocks in Nigeria, this distinction is worth paying attention to: a limit order can give you more control, but control doesn’t guarantee execution.
Common Mistakes to Avoid When Placing Stock Orders
Knowing the difference between market and limit orders is useful, but investors can still make mistakes when placing trades.
Here are some to watch out for.
1. Assuming the displayed price is guaranteed
The price you see on a trading platform represents information about the market at that moment. It doesn’t automatically guarantee that your market order will execute at exactly that price.
2. Setting an unrealistic limit price
A limit order only works if the market reaches the price you’ve specified. Setting a price far away from the prevailing market price could mean your order remains unfilled.
3. Ignoring liquidity
A stock can have limited buying and selling activity. This matters because available orders may affect how easily and at what price your trade is executed.
4. Choosing an order type without understanding it
Don’t select an order simply because it appears first on the screen. Know what will happen after you submit it.
5. Focusing only on the order type
Market and limit orders determine how you communicate your trade instruction. They don’t replace proper research.
Before buying a stock, consider the company’s fundamentals, financial performance, valuation, industry, risk and your own investment objectives.
Learning how to trade stocks in Nigeria involves understanding both what you’re buying and how you’re buying it.
Frequently Asked Questions
Are market orders and limit orders available for Nigerian stocks?
The order types available can depend on the brokerage platform and the market infrastructure supporting the trade. Check your trading platform to see which order types are available for the stocks you’re looking to trade.
Can a limit order fail to execute?
Yes. If the market doesn’t reach your specified price, or there aren’t enough matching orders at the relevant price, your limit order may remain unfilled.
Can a market order execute at a different price from the one I see?
Yes. A market order is executed at the best available price when the order is matched. That price can differ from the price displayed when you submitted the order.
Which order type is better for beginners?
Neither is automatically better. Beginners should first understand the difference between the two and choose based on whether they prioritise execution or price control.
Can I cancel a limit order?
This depends on the status of the order and the trading platform you’re using. An order that has already been executed generally cannot be cancelled, while an outstanding order may be cancellable depending on the platform’s rules.
What happens if my limit order isn’t filled?
If the market doesn’t meet your specified price within the applicable order period, the order may remain unfilled or expire, depending on the order’s terms and your broker’s system.
