In a strategic move to enhance trading flexibility and reduce entry barriers, OKX has announced an upcoming adjustment to the minimum order size and order quantity precision for select perpetual and delivery contracts. This change is set to take effect on March 14, 2025, between 2:00 PM and 4:00 PM (UTC+8), aiming to improve user experience by enabling finer control over trade sizing.
The update will allow traders to place smaller orders with greater precision—particularly beneficial for users managing risk in volatile markets or those looking to optimize position sizing with limited capital. This article outlines the key details of the adjustment, explains essential trading concepts, and provides clarity on how these changes impact both manual and automated trading strategies.
Contracts Affected by the Update
The following contracts will see adjustments in both minimum order size and order quantity precision, reducing from 1 contract to 0.1 contract:
- LTCUSDT Delivery Contract
- LTCUSDT Perpetual Contract
- SHIBUSDT Perpetual Contract
This means traders will now be able to open positions as small as one-tenth of a contract, offering significantly more flexibility compared to the previous whole-contract requirement.

Understanding Key Trading Terms
To fully grasp the impact of this update, it's important to understand two core concepts: order quantity precision and minimum order size.
What Is Order Quantity Precision?
Order quantity precision refers to the smallest increment by which a contract order size can change. It defines how granular your trade sizing can be.
For example:
- The ETHUSDT perpetual contract has a contract value of 0.1 ETH.
- With an order quantity precision of 0.1 contracts, you can adjust your order size in increments of 0.1 (i.e., 0.01 ETH).
- This allows for orders like 1.0, 1.1, 1.2 contracts, etc.
This level of granularity supports more accurate position management and risk allocation.
What Is Minimum Order Size?
Minimum order size is the smallest number of contracts you can trade in a single order. It must always be a multiple of the order quantity precision.
Using the same ETHUSDT example:
- If the minimum order size is 1 contract (0.1 ETH), you cannot place an order for less than that.
- However, once precision allows increments of 0.1, you can scale up from 1.0 to 1.1, 1.2, etc.
With the new changes, the minimum drops to 0.1 contracts, meaning users can now enter positions worth just 10% of the original minimum—a game-changer for micro-positioning.
Updated Position and Order Display Rules
After the adjustment, any contract with an order quantity precision below 1 will support decimal-based display for:
- Open positions (holdings)
- Active limit and market orders
- Partially filled orders
- Conditional and stop orders
Real-World Example: SHIBUSDT Perpetual Contract
Before:
- Contract value: 1,000,000 SHIB
- Order precision: 1 contract
- Minimum order: 1 contract (1,000,000 SHIB)
- A position of 1 contract = exactly 1,000,000 SHIB
After:
- New precision: 0.1 contract
- New minimum: 0.1 contract (100,000 SHIB)
- You can now hold or trade 1.5 contracts = 1,500,000 SHIB
- Orders like 10.5 contracts (10,500,000 SHIB) are fully supported
This update makes it easier to express precise market views without overexposure—especially valuable for low-value, high-supply assets like Shiba Inu.
How Orders Will Be Processed Post-Adjustment
All new orders and modifications must comply with the updated rules:
Key Rules for Placing or Modifying Orders:
- The order size must be a multiple of the new order quantity precision (0.1)
- The order size must be equal to or greater than the new minimum (0.1)
Example: SHIBUSDT Perpetual Contract After Adjustment
- Precision: 0.1 contract = 100,000 SHIB
- Valid order sizes: 0.1, 0.2, 0.3 … 5.7, 5.8, etc.
- Invalid sizes: 0.15, 0.23 (not multiples of 0.1)
This ensures system consistency while expanding access to fractional trading.
✅ Applies to all users: manual traders, API bots, algorithmic strategies, and copy-trading followers.
No disruption will occur during the transition—existing open orders, margin transfers, leverage adjustments, and active positions remain unaffected.
Implications for API and Algorithmic Traders
Developers and institutional users relying on automated systems should note the following updates:
API & WebSocket Changes
- The
lotSz(lot size) field in all relevant endpoints will reflect the new precision value (e.g., 0.1) - The
minSz(minimum size) field will also be updated accordingly - These changes apply to both REST API and real-time WebSocket feeds
Traders using custom scripts or third-party tools must ensure their logic accounts for:
- Smaller valid increments
- Lower minimum thresholds
- Potential rounding errors when calculating position sizes
