In the world of cryptocurrency trading, encountering a "partially filled" order on OKX can be confusing—especially if you're new to digital asset exchanges. You place a limit order, refresh the page, and see “partially filled” instead of “fully executed.” Your coins haven’t arrived in full, but the order hasn’t disappeared either. So what does this mean? Is your trade still active? And most importantly: Will the remaining portion be automatically cancelled?
The short answer is: No, not under normal circumstances. Let’s dive deep into how partial fills work on OKX, what happens to the unfilled portion of your order, and how you can manage it effectively.

Understanding Partially Filled Orders on OKX
When you place a limit order on OKX, you're specifying both the price and quantity at which you want to buy or sell a cryptocurrency. The exchange then attempts to match your order with existing opposing orders in the order book.
However, if there aren't enough matching orders at your specified price, only a portion of your trade may execute immediately. This results in a partially filled status.
Example Scenario:
Imagine you want to buy 1 BTC at 25,000 USDT, and you submit a limit order. At that moment, only 0.3 BTC is available for sale at 25,000 USDT. The system will fill 0.3 BTC right away, while the remaining 0.7 BTC stays in the order book as an open (or "pending") order.
This is completely normal and reflects the dynamics of market liquidity and price alignment.
A partially filled order means part of your trade has been executed; the rest remains active until fully filled, manually cancelled, or removed due to specific conditions.
Does OKX Automatically Cancel Unfilled Portions?
Here’s where many traders get confused.
✅ Standard Behavior:
On OKX, unless you’ve selected special order types or strategies, the unfilled portion of a limit order will NOT be automatically cancelled. It remains in the order book indefinitely—waiting for a match.
So yes:
➡️ If 10% of your order fills today, the other 90% stays live tomorrow, next week, or even months later—provided no changes occur.
Only under certain conditions will OKX cancel the remaining amount:
- IOC (Immediate or Cancel) Orders: Must execute immediately; any unfilled portion is cancelled.
- FOK (Fill or Kill) Orders: Entire order must fill instantly—or it's rejected altogether.
- Post Only Orders: Automatically cancelled if they would result in taking liquidity (i.e., executing immediately).
- System-Level Interventions: Such as trading pair delisting, maintenance, or suspension.
- Account Risk Events: Like margin calls in futures trading, where open orders may be cancelled to reduce exposure.
For most spot traders using regular limit orders, your unfilled portion stays active.

How to Check the Status of Your Partially Filled Order
You can easily monitor your open and completed trades directly through the OKX platform:
On Web or App:
- Go to the [Trading] section.
- Tap [Orders] or [Current Orders].
- Look for your relevant trading pair (e.g., BTC/USDT).
Check the status:
- ✅ Partially filled: Still active; waiting for more matches.
- ❌ Cancelled: Order was withdrawn (by you or the system).
- ✔️ Fully filled: All units have been traded.
You can also view historical data under [Order History] to track past partial executions and analyze market behavior around your entry points.
Should You Manually Cancel a Partially Filled Order?
This depends entirely on your trading strategy and current market conditions.
Consider Cancelling If:
- Market price has moved significantly away from your limit price.
- You no longer believe the asset will reach your target level.
- You need to free up funds or margin for other opportunities.
- You’re managing risk in leveraged positions and want to avoid unnecessary exposure.
It’s Safe to Leave It Open If:
- You're placing a strategic entry (e.g., a long-term buy at a desired low price).
- You're using dollar-cost averaging (DCA) and welcome incremental fills.
- Liquidity is typically low for that pair—you expect slow but eventual execution.
Always assess whether keeping an open order aligns with your overall portfolio goals.
Frequently Asked Questions (FAQ)
Q1: Will my partially filled order expire after some time?
No—unless you set an expiry (like in time-in-force options), standard limit orders on OKX do not expire. They remain active until filled or manually cancelled.
Q2: Can I modify the price of a partially filled order?
Unfortunately, no. Once an order is placed, you cannot edit its price or quantity. To adjust, you must cancel the remaining portion and place a new order.
Q3: Why didn’t my entire order fill even though the market reached my price?
Even if the market touches your price, there must be sufficient sell/buy depth at that level. High volatility or low liquidity can prevent full execution.
Q4: Does a partial fill affect my trading fees?
Yes. Fees are charged only on the executed portion. So if 0.3 BTC fills, you pay fees on 0.3 BTC—not the full amount.
Q5: Can I automate responses to partial fills?
Yes—using OKX’s API or advanced trading bots, you can set rules to cancel, replace, or scale orders based on partial execution events.
Q6: Is partial filling common on OKX?
Very. Especially for large orders or less liquid pairs. It's a normal function of decentralized matching engines and reflects real-time supply-demand imbalances.
Key Takeaways for Traders
