A limit order is a powerful trading tool that allows you to buy or sell a cryptocurrency at a specific target price or better. Unlike market orders, which execute immediately at the current market rate, limit orders give you control over your entry and exit points. This means you can set your desired price and wait for the market to reach it, without needing to monitor price fluctuations constantly.
This feature is particularly useful in volatile markets, where prices can change rapidly. By using limit orders, you can automate your trading strategy, reduce emotional decision-making, and potentially achieve better trade execution. Currently, this functionality is supported on multiple major blockchain networks, including Ethereum, BNB Chain, OKTC, Polygon, Avalanche C, Fantom, Arbitrum, and Optimism.
How Does a DEX Limit Order Work?
When you place a limit order on a decentralized exchange (DEX), you are essentially creating a conditional trade instruction. You specify the token pair, the amount you want to trade, your desired price, and an expiration time for the order.
The order will only execute if the market reaches your specified price. For buy orders, execution occurs when the market price falls to your target price or lower. For sell orders, it happens when the market price rises to your target or higher. It's important to remember that network fees are factored into execution. Specifically, a limit buy order will execute when the market price equals your specified price plus the network fee.
This system operates entirely on-chain through smart contracts, ensuring transparency and security without intermediaries.
How to Place a Limit Order on Mobile App
Using a mobile application provides a convenient way to manage your trades on the go. Here's how to set up a limit order through most DEX interfaces:
- Navigate to the Trade section and select Limit order from the available options.
Fill in the details:
- Select the tokens you wish to sell and buy.
- Enter your preferred exchange rate.
- Set an expiry period for the order.
- Review all parameters and select Place limit order.
Remember, you can fully customize your price and order expiry before finalizing the transaction. This allows for strategic planning based on your market analysis.

Managing Your Limit Orders
After placing an order, it's important to know how to track and manage it. You retain full control over your active limit orders and can cancel them at any time before they are filled.
On the Mobile App
- To view your transaction history, select the history icon typically located in the top right corner of the app interface. This centralized hub lets you track all orders and their statuses.
- If you wish to cancel an active order, select the specific transaction from your history. Within the transaction details, you will find a Cancel option.
On the Web Platform
- In the main Trade interface, click on the history icon situated in the top right corner. Here, you can see all your transactions and their current status listed clearly.
- To cancel a pending limit order, simply select the relevant transaction and choose the Cancel button in the Transaction details panel.
Key Considerations for Limit Orders
- Market Price Option: Most platforms offer a "Use market price" option for immediate execution at the best available current price, which is different from a limit order.
- Fee Structure: Network fees (gas fees) are only charged at the moment your limit order is successfully executed, not when you place the order.
- Price Accuracy: Always account for network fees in your target price calculation, especially for buy orders, as execution requires the market price to meet your specified price plus fees.
- Liquidity: The execution of your order depends on market liquidity. If there aren't enough tokens available at your price, the order may only be partially filled.
Frequently Asked Questions
What is the main advantage of using a limit order?
The primary advantage is price control. It allows you to set exact entry and exit points, preventing you from overpaying for assets during sudden price spikes or selling for less than intended during market dips. It automates your strategy based on predefined parameters.
Can a limit order expire without being filled?
Yes, absolutely. When you place a limit order, you set an expiration time. If the market never reaches your specified price before that expiry time elapses, the order will simply cancel automatically without being executed, and no network fees will be incurred.
Is there a cost to placing a limit order?
There is usually no upfront cost to place a limit order. Network gas fees are only charged if and when the order is successfully executed on the blockchain. Placing the order itself is typically a gas-free interaction.
What's the difference between a limit order and a market order?
A market order executes immediately at the current best available market price, prioritizing speed over price control. A limit order prioritizes price control, allowing you to set a specific execution price, but it is not guaranteed to fill if the market doesn't reach your price.
How do I know if my limit order was successful?
You can monitor the status of your order in your transaction history on the platform. It will show as "Open" or "Pending" until it is either executed or canceled. Once filled, it will be marked as "Completed".
Can I modify a limit order after placing it?
Generally, you cannot modify the parameters of an existing limit order. The standard process is to cancel the existing order and create a new one with your updated desired price, amount, or expiry time.
