OKX Adjusts Minimum Order Size for Selected Contracts to Enhance Trading Flexibility

·

Starting March 14, 2025, from 2:00 PM to 6:00 PM (UTC+8), OKX will implement a strategic update to improve trading accessibility by adjusting the minimum order size and order quantity precision for select perpetual and delivery contracts. This change is designed to lower entry barriers, support finer trade control, and enhance overall user experience across both spot and derivatives markets.

The adjustment applies specifically to LTCUSDT and SHIBUSDT perpetual contracts, as well as the LTCUSDT delivery contract. By reducing the smallest allowable trade size from 1 contract to just 0.1 contracts, OKX empowers traders—especially retail and precision-focused users—to execute more flexible positions with better risk management.

Understanding Minimum Order Size and Quantity Precision

To fully appreciate the impact of this update, it's essential to understand two key trading parameters: minimum order size and order quantity precision.

What Is Order Quantity Precision?

Order quantity precision refers to the smallest incremental unit by which a futures or perpetual contract order can be adjusted. It defines how granular your trade size can be.

For example, if the ETHUSDT perpetual contract has a contract value of 0.1 ETH and an order quantity precision of 0.1 contracts, then each step in your order size increases by 0.1 contracts (equivalent to 0.01 ETH). This means you can place orders at 1.0, 1.1, 1.2 contracts, etc., enabling fine-tuned position sizing.

What Is Minimum Order Size?

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

Using the same ETHUSDT example: if the minimum order size is 1 contract and the precision is 0.1, you must place orders of at least 1 contract (0.1 ETH), but you can increase in steps of 0.1 contracts—such as 1.1, 1.3, or 2.5 contracts.

This distinction ensures that while traders have flexibility in adjusting their positions, there’s still a defined floor to prevent micro-orders that could impact system stability.

Key Changes to Contract Specifications

Below are the updated specifications for the affected contracts:

These updates mean users can now open positions as small as 0.1 contracts, significantly lowering capital requirements—especially beneficial for high-denomination tokens like SHIB where one full contract represents 1,000,000 SHIB.

For instance:

This enables better exposure control, improved hedging strategies, and reduced slippage risk for partial fills.

Updated Position and Order Display Rules

Following the adjustment, all user interfaces—including web, mobile, and third-party tools—will support decimal-based display for both open positions and pending orders when the order quantity precision is less than 1.

This includes:

This enhancement benefits not only manual traders but also those using automated systems who require accurate data representation for performance tracking and execution logic.

Order Execution and Modification Rules

All new orders and modifications must adhere to the updated rules:

Example:

These rules apply universally across:

No exceptions will be made during or after the transition window.

Impact on API and Automated Trading Systems

Developers and algorithmic traders should note that the following API fields will be updated automatically after the change:

WebSocket streams will also broadcast these updated values in real time.

Traders using automated bots, grid strategies, or third-party tools are strongly encouraged to:

Failure to adapt may result in rejected orders or unintended position sizing.
