Risk Notice: Temporary Trading Suspension

During the adjustment window:

• Trading will be temporarily paused for 2 minutes only for pairs where the price tick is being reduced (i.e., increased precision).
• Affected users cannot place or cancel orders, add margin, or transfer funds during this brief period.
• All other trading pairs remain unaffected and fully operational.

This short suspension ensures system stability and accurate migration to the new tick structure.

Order Handling Rules During Adjustment

Case 1: Price Tick Reduced (e.g., from 0.01 to 1e-6)

When precision increases (tick size decreases), existing orders are evaluated based on their price formatting:

a. Limit Orders

• Orders with price precision greater than the new tick size will be automatically canceled.
• Orders with precision equal to or less than the new tick size remain valid.

Example:
If the new tick is 1e-6, an order at 135.2442 (too precise) will be canceled, while one at 135.244 survives.

b. Conditional & Strategy Orders

All conditional orders (e.g., stop-loss, take-profit) follow the same rule:

• If price exceeds new precision → canceled.
• Otherwise → retained.

Impact on Automated Strategies:

• Grid & Martingale strategies (Spot Grid, Contract Grid, Infinity Grid, Martingale) — if active orders are canceled, the entire strategy stops.
• Other strategies (DCA, TWAP, Iceberg, Arbitrage, etc.) — canceled orders do not terminate the strategy; it resumes under new precision rules after maintenance.

Case 2: Price Tick Increased (e.g., from 1e-6 to 1e-4)

When precision decreases:

• All existing orders remain active.
• No cancellations occur.
• System continues normal matching.

API User Guidance

API traders are subject to the same logic but benefit from added flexibility:

• If submitting orders using old precision (e.g., x.xxx444 when new tick is x.xxx), the system will automatically truncate the excess digits.
• Example: Sending 98.7654 with a tick of 98.76 becomes 98.76 — order succeeds.
• In contrast, web and mobile users cannot submit improperly formatted prices and will receive validation errors.

Developers should update their systems to reflect new tick sizes to avoid unintended truncation or suboptimal execution.

Historical Data & Position Display Logic

After adjustment, display behavior varies by interface:

For Web & Mobile Users

• Price Tick Reduced: Historical trades and open positions are shown under the new precision.

  • Buy prices: Rounded down (truncated).
  • Sell prices: Rounded up (ceiling).
• Price Tick Increased: Prices continue displaying at original precision for consistency.

For API Users

• Historical data retains original precision regardless of change direction.
• Ideal for backtesting and audit trails requiring raw data fidelity.

Frequently Asked Questions (FAQ)

Q: Why is OKX adjusting minimum price precision?

A: To enhance market depth and allow tighter spreads, especially for volatile or high-volume assets like SHIB and CRV. Finer pricing enables more accurate trade execution.

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

A: No. Open positions are unaffected by tick size changes unless forced by price movement or margin levels.

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

A: If your grid strategy uses high precision that no longer complies with the new tick, it may stop. Review your bot settings post-update or consider switching to adaptive grids.

Q: How long will trading be paused?

A: Only 2 minutes for specific pairs undergoing increased precision. Most users won’t experience any downtime.

Q: Can I still trade other pairs during the maintenance?

A: Yes. The adjustment affects only listed pairs. All others operate normally.

Q: Where can I check updated tick sizes programmatically?

A: Use the OKX API endpoint /api/v5/public/instruments to retrieve real-time contract and spot specifications, including tick_size.
