OKX Announces Adjustment to Minimum Order Size for Select Perpetual Contracts

·

To enhance trading experience and reduce transaction barriers, OKX will adjust the minimum order size and order quantity precision for select perpetual contracts on June 6, 2024, from 2:00 PM to 4:00 PM (UTC+8). This update aims to provide traders with greater flexibility, especially those engaging in smaller or more precise positions.

The adjustment will apply to specific USDT-margined perpetual contracts and will refine both the minimum tradable quantity and the granularity of order inputs. Importantly, all ongoing trading activities—including order placement, fund transfers, and leverage adjustments—will remain fully functional during the transition.

Updated Contract Specifications

The following contracts will see a reduction in both minimum order size and quantity precision, enabling finer control over trade sizing:

These changes mean traders can now open smaller positions and adjust orders in smaller increments, improving accessibility for retail traders and allowing for more nuanced risk management.

Understanding Key Trading Parameters

What Is Order Quantity Precision?

Order quantity precision refers to the smallest increment by which a contract’s order size can be adjusted. It defines how granular your trade entries can be.

For example, if the ETHUSDT perpetual contract has a contract value of 0.1 ETH and an order precision of 0.1 contracts, each increment equals 0.01 ETH. This means you can place orders in steps like 0.1, 0.2, or 1.5 contracts—offering flexibility in position sizing.

What Is Minimum Order Size?

The minimum order size is the smallest number of contracts you can trade in a single order. It is always a multiple of the order quantity precision.

Using the same ETHUSDT example:

You must place orders of at least 1 contract but can increase in 0.1-contract increments (e.g., 1.1, 1.2, etc.).

After the update, contracts like FET/USDT will allow orders as small as 0.1 contract, making it easier for traders with limited capital to participate.

Updated Display Rules for Positions and Orders

Following the adjustment, when the order quantity precision is less than 1, both open positions and pending orders will support decimal-based display.

For instance:

This change benefits all users—including those using APIs, algorithmic trading, and copy trading—by enabling more precise position tracking and execution.

This allows micro-adjustments in volatile markets and supports better stop-loss/take-profit placement.

These rules apply uniformly across:

API and WebSocket Updates

Ensure your trading bots, dashboards, or risk engines account for these changes to avoid invalid order rejections. Refer to official API documentation for integration guidance.

Frequently Asked Questions (FAQ)

Q: When will the minimum order size change take effect?

The adjustment will go live on June 6, 2024, between 2:00 PM and 4:00 PM (UTC+8). No action is required from users—the system will automatically apply the new rules after the update.

Q: Will my open positions or pending orders be affected?

No. Your existing positions and unfilled orders will remain intact. The update only affects the creation or modification of new orders after the change.

Q: Can I place an order smaller than the minimum size?

No. All new orders must meet or exceed the updated minimum order size and be a multiple of the order quantity precision.

Q: Does this change apply to all contract types?

No. Only select USDT-margined perpetual contracts are affected—specifically FET/USDT, SOL/USDT, STX/USDT, and THETA/USDT.

Q: How does this benefit small-scale traders?

Lower minimums allow traders with smaller accounts to enter positions with less capital exposure, improving accessibility and risk control.

Q: Do I need to update my API integration?

Yes. If your system relies on lotSz or minSz, ensure it pulls updated values after June 6. Hardcoding old values may result in rejected orders.
