Starting March 14, 2025, from 2:00 PM to 6:00 PM (UTC+8), OKX will implement an important update to enhance trading flexibility and reduce transaction barriers for users. The platform will adjust the minimum order size and order quantity precision for select perpetual and delivery contracts. This change is designed to support finer trade control, especially for traders managing smaller positions or executing precise risk management strategies.
The affected contracts include LTCUSDT and SHIBUSDT, with both delivery and perpetual variants seeing significant improvements in order granularity. These updates reflect OKX’s ongoing commitment to refining user experience and supporting diverse trading styles — from casual investors to advanced algorithmic traders.

What Are Minimum Order Size and Order Quantity Precision?
Before diving into the specifics, it's essential to understand two core concepts:
- Order quantity precision refers to the smallest increment by which you can adjust your order size when placing a trade on perpetual or delivery contracts.
- Minimum order size is the smallest number of contract units (lots) you can trade in a single order. It must be a multiple of the order quantity precision.
For example, take the ETHUSDT perpetual contract with a contract value of 0.1 ETH and an order precision of 0.1 lot. This means:
- You can increase or decrease your position in increments of 0.1 lot (0.01 ETH).
- If the minimum order size is 1 lot (0.1 ETH), you must place orders equal to or greater than that amount — such as 1.0, 1.1, or 1.5 lots.
With the upcoming changes, users gain even more control over position sizing, enabling micro-adjustments that were previously not possible.
Detailed Contract Adjustments
The following contracts will see their minimum order size and order quantity precision reduced from 1 lot to 0.1 lot, allowing for ten times finer control:
| Contract Type | Symbol | Before Adjustment (Lots) | After Adjustment (Lots) |
|---|---|---|---|
| Delivery Contract | LTCUSDT | 1 | 0.1 |
| Perpetual Contract | LTCUSDT | 1 | 0.1 |
| Perpetual Contract | SHIBUSDT | 1 | 0.1 |
This means traders can now open positions as small as 0.1 lot, making these contracts far more accessible for users with limited capital or those testing new strategies with minimal exposure.
For SHIBUSDT, where each lot represents 1,000,000 SHIB tokens, this adjustment allows orders like 10.5 lots (10,500,000 SHIB) instead of being restricted to whole numbers. Similarly, traders holding a position of 1.5 lots (1,500,000 SHIB) will now be able to display and manage fractional holdings directly.
These improvements apply across all user types — including manual traders, API users, bot operators, and those using copy trading or grid strategies.
How Position and Order Displays Will Change
After the update:
- All positions and open orders — whether fully filled, partially executed, pending, or inactive — will support decimal-based display if the order precision is less than 1.
- Users will see their holdings and pending trades shown with up to one decimal place (e.g., 5.3 lots), improving clarity and accuracy in portfolio tracking.
This change enhances transparency and helps traders better visualize their exposure without rounding errors or estimation gaps.

Updated Order Submission Rules
With the new precision settings in place, the rules for placing or modifying orders are also updated:
- Your order quantity must be a multiple of the new order precision (0.1 lot).
- The total order size must be equal to or greater than the new minimum (0.1 lot).
For instance:
On SHIBUSDT perpetual contracts:
- Previously: Orders had to be in whole lots (e.g., 1, 2, 3…).
- Now: You can place orders like 0.1, 0.5, 1.7, or 2.9 lots — all valid as long as they’re multiples of 0.1.
This increased flexibility benefits scalpers, hedgers, and algorithmic traders who rely on precise position adjustments.
All trading interfaces — web, mobile app, API, and third-party integrations — will enforce these rules uniformly.
Impact on API and Automated Trading Systems
Developers and institutional users relying on automated systems should note that the following API fields will be updated:
lotSz(order quantity precision)minSz(minimum order size)
Both values will reflect the new 0.1 lot standard for the affected contracts. WebSocket streams will also transmit updated contract parameters in real time.
Users are strongly encouraged to:
- Review the OKX API documentation for upcoming changes.
- Test their bots or trading scripts in the sandbox environment.
- Update any hardcoded thresholds or validation logic that assumes integer-only lot sizes.
Failure to adapt may result in rejected orders or unintended trade behavior during live execution.

Frequently Asked Questions (FAQ)
Q: When will the changes take effect?
A: The adjustment will go live on March 14, 2025, between 2:00 PM and 6:00 PM (UTC+8). No action is required during this window — the update is seamless.
Q: Will my open orders or positions be affected?
A: No. All existing orders and positions remain valid. Only future orders must comply with the new precision and minimum size rules.
Q: Can I still place orders in whole lots?
A: Yes. While you now have the option to use decimal lots (e.g., 1.3), placing whole-number orders (e.g., 2.0) is still fully supported.
Q: Does this apply to all contracts on OKX?
A: Not at this time. Only LTCUSDT (delivery and perpetual) and SHIBUSDT (perpetual) are included in this phase. More contracts may follow based on user feedback.
Q: Why is OKX making this change?
A: To improve trading accessibility, allow finer risk control, and support a wider range of trading strategies — especially for users with smaller account balances.
Q: Do I need to update my API code?
A: If your system assumes fixed lot sizes or hardcodes minSz or lotSz, yes — you should retrieve these values dynamically from the API rather than relying on static assumptions.
