Placing orders is a daily activity for every trader using OKX for perpetual swap trading. You've chosen your direction, entered your price and quantity, and clicked "Place Order" to submit your limit order. However, once an order is placed, the market can sometimes begin to fluctuate wildly. At this point, many users' first reaction is: "Can I change the price I set?" or "The order hasn't been filled yet, should I cancel and re-place it?"
This article provides a detailed explanation of whether you can modify the price after placing an order on OKX perpetual swaps and how to manage unfilled limit orders. In highly volatile markets, timely adjustments to your order strategy can be a crucial operation for reducing slippage and improving fill rates.
Can You Directly Modify the Price After Placing a Perpetual Swap Order?
The answer is no. In the current mechanism of OKX, once a perpetual swap order is submitted, it enters the trading matching system to await execution. It is not possible to modify the price or quantity of the order without first canceling it. To change the order price, you must first cancel the existing order and then place a new one. This logic is consistent with the operation in spot trading and is designed to ensure the fairness and consistency of the matching system.
How to Cancel an Unfilled Order?
The operation is very simple. Whether you are using the OKX app or the OKX web platform, you can view all your unfilled orders in the "Current Orders" section. You can:
- In the [Current Orders] section at the bottom of the perpetual swap trading interface on the OKX website, select the corresponding order and click "Cancel".
- Or click "Cancel All" to remove all unfilled limit orders.
- If you have set up strategic orders, you can also manage and cancel them collectively in the [Strategy Orders] section.
After canceling the order, you can reset your limit order based on the current market price, allowing for more flexible responses to market changes.
Can You Set Up Automatic Cancellation or Adjustment Logic?
Currently, OKX supports certain strategy types such as plan delegation, conditional orders, and trailing stop-profit, which can help you automatically place orders or cancel existing ones when preset conditions are met. However, these are advanced features and are not provided by default with ordinary limit orders. If you are using a standard perpetual swap order (limit/market order), you still need to manage unfilled orders manually.
Why Do Orders Sometimes Remain Unfilled for a Long Time?
The main reasons for orders not being filled include:
- The order price is too far from the current market price: For example, your set buy price is too low, or your sell price is too high.
- Insufficient market trading volume: This is especially common with less popular cryptocurrencies or during periods of low volatility.
- Low priority in the platform's matching queue: For instance, your order might be at the end of the execution queue.
- Network latency or connection abnormalities: These can prevent the order from being submitted promptly or its status from being updated correctly.
When the market moves rapidly, a previously "reasonable" order price can instantly become irrelevant, necessitating proactive adjustment from you.
Practical Advice: How to Manage Orders Dynamically After Placement
Although you cannot directly modify the price, you can improve efficiency through the following methods:
- Maintain a high page refresh rate: Ensure you see the latest order status.
- Set price alerts: The OKX app supports notifications for when a price level is reached, allowing for timely strategy adjustments.
- Use take-profit/stop-loss orders in conjunction with limit orders: This ensures that regardless of whether the order is filled, subsequent risk control measures are in place.
- Avoid placing large, static orders during high volatility: When the market is active, your order strategy should also be flexible.
Every time you promptly cancel an order and place a new one at a different price, you are actively managing risk and opportunity.

Frequently Asked Questions
Can I change the order quantity after placing a perpetual swap order on OKX?
No, similar to the price, the order quantity cannot be modified after placement. You must cancel the existing unfilled order and create a new one with the desired quantity.
Is there a fee for canceling an unfilled limit order on OKX?
Typically, OKX does not charge a fee for canceling unfilled orders. You are only charged a maker or taker fee when an order is successfully executed (filled).
What is the difference between a limit order and a market order in this context?
A limit order is placed at a specific price and will only execute at that price or better. It may remain unfilled if the market doesn't reach your price. A market order executes immediately at the current best available market price but offers no price control. Market orders cannot be modified or canceled once placed as they are intended for immediate execution.
How quickly is an order canceled after I click the button?
Cancellation is usually processed almost instantly by the OKX matching engine. However, in periods of extreme market volatility or high system load, there might be a minimal delay.
What happens if the market hits my price just as I try to cancel?
There is a small possibility that your cancellation request and a matching order could be processed at nearly the same time. If the order is filled before the cancellation is confirmed, the cancellation will fail for that filled quantity.
In summary, on OKX, you cannot directly modify the price after placing a perpetual swap order. If an adjustment is needed, you must cancel the order first and then place a new one. While this operation might seem like an "extra step," it ensures that users maintain clear awareness and control over every single order, avoiding potential misunderstandings or risks that could arise from automatic system changes. It is recommended that every perpetual swap trader develops good order management habits—ne blindly believing in "set-and-forget" positions nor chasing the market with frequent orders. Grasp the rhythm of the market and place orders at prices you want to trade at, rather than hoping the market will accommodate you.
