Risk Notice During Adjustment Window

During the transition period, temporary trading interruptions may occur depending on the direction of the precision change:

• Precision reduced (e.g., from 0.0001 → 0.01): Affected assets will experience a 2-minute trading suspension. During this time, users cannot:

  • Place or cancel orders
  • Add margin
  • Transfer funds

  All other trading pairs remain unaffected.

• Precision increased (e.g., from 0.01 → 0.0001): No trading disruption occurs. Orders continue to be processed normally.

This ensures system stability while accommodating structural updates to price tick sizes.

Order Handling Rules During Precision Adjustment

To maintain market fairness and technical consistency, OKX has established clear rules for handling open orders during the adjustment phase.

1. When Price Precision Is Reduced (e.g., from 0.0001 → 0.01)

a. Limit Orders

• Orders with price precision greater than the new standard will be automatically canceled.
• Orders with price precision less than or equal to the new standard will remain active.

Example:

• An order priced at 130.2442 will be canceled (too precise).
• An order priced at 130.24 will remain (within new limits).

b. All Conditional & Strategy Orders

• Same logic applies: if the price exceeds the new precision level, the order is canceled.

Impact on Automated Strategies:

• Grid and Martingale-based strategies (including Spot Grid, Contract Grid, Infinity Grid, Dual Grid, Spot Martingale, Contract Martingale):
  If any associated orders are canceled due to precision mismatch, the entire strategy will terminate.
• Other strategies (e.g., Signal Trading, Time-Weighted Average Price, Iceberg Orders, Dollar-Cost Averaging, Arbitrage, Take-Profit/Stop-Loss, Trailing Stop, Plan Orders):
  Canceled orders do not stop the strategy. Upon resumption, these strategies will re-submit orders using the updated price precision.

2. When Price Precision Is Increased (e.g., from 0.01 → 0.0001)

All existing orders — whether limit, conditional, or strategy-based — will remain fully intact and unaffected.

This allows traders to maintain position integrity while benefiting from finer pricing control post-adjustment.

Historical Data and Position Display Rules

How your past trades and current holdings appear depends on the direction of the precision change.

1. Precision Reduced (e.g., from 0.0001 → 0.01)

• Web and Mobile Users:
  Historical orders and positions will be displayed using the new precision level, following these rounding rules:

  • Buy orders: Rounded down (truncated)
  • Sell orders: Rounded up (ceiling)

  This preserves consistency across interfaces while aligning with current market formatting.

• API Users:
  Historical data retains the original precision used at the time of execution. No rounding is applied.

2. Precision Increased (e.g., from 0.01 → 0.0001)

No changes to display logic — all data continues to show at the original or higher precision level.

Special Considerations for API Traders

API users are subject to the same order handling rules but benefit from additional flexibility:

• After a precision reduction (e.g., from 0.0001 to 0.01), if an order is submitted using the old precision (130.2442), the system will automatically truncate it to match the new standard (130.24), allowing successful execution.
• In contrast, web and mobile users cannot submit orders using outdated precision — such attempts will be rejected by the interface.

This ensures backward compatibility for algorithmic traders while maintaining data integrity across platforms.

Frequently Asked Questions (FAQ)

Q: Why is OKX adjusting the minimum price precision?

A: The adjustment aims to improve market efficiency and liquidity by aligning price steps with current trading volume and user behavior patterns. Finer or coarser pricing helps reduce slippage and enhances overall trade execution quality.

Q: Will my open positions be liquidated during the adjustment?

A: No. Position liquidation is not triggered by price precision changes. Only certain types of open orders may be canceled based on precision mismatch, but your holdings remain secure.

Q: Do I need to manually adjust my grid bots before the change?

A: If your grid strategy operates on a pair undergoing reduced precision, it’s advisable to review your settings beforehand. After cancellation due to precision issues, grid strategies will not restart automatically.

Q: How does this affect stop-loss or take-profit orders?

A: For non-grid strategies like stop-loss or trailing stop, canceled orders won’t halt the strategy. Once trading resumes, new orders will be placed under updated precision rules.

Q: Can I still use my existing scripts as an API trader?

A: Yes. API submissions with outdated precision are automatically truncated to comply with new standards, ensuring continued operation without code changes in most cases.

Q: Where can I check the latest precision for a trading pair?

A: You can find updated trading rules under “Fees & Limits” in the OKX help center or via the API endpoint /api/v5/public/instruments.
