OKX Announces Adjustments to Minimum Price and Quantity Precision for Spot, Margin, and Perpetual Contracts

To enhance market liquidity and improve trading experience, OKX will adjust the minimum price precision and trading quantity precision for select spot, margin, and perpetual contract trading pairs on July 28, 2023, from 14:00 to 16:00 (UTC+8). These changes apply across spot, margin, and derivatives markets, with certain pairs undergoing temporary trading pauses during implementation.

This update is part of OKX’s ongoing commitment to refining platform mechanics, ensuring greater precision in pricing and order execution, and supporting evolving market demands.

🔧 Overview of Precision Adjustments

Precision adjustments affect how prices and trade amounts are displayed and executed on the exchange. These updates fall into two main categories:

• Minimum Price Precision: The smallest increment by which a price can change.
• Trading Quantity Precision: The smallest divisible unit for trading volume.

Adjustments are made to either increase granularity (e.g., from 0.001 to 0.0001) or reduce excessive precision based on market conditions and trading behavior.

📉 Trading Quantity Precision Adjustments

For select trading pairs, the quantity step size will be adjusted downward—meaning fewer decimal places will be supported. During this transition, affected markets will pause trading for 2 minutes to ensure a smooth migration.

Affected Spot Trading Pairs

Note: Margin trading pairs will be adjusted simultaneously if applicable.

These adjustments streamline order entry for low-liquidity assets where ultra-fine quantity steps offer minimal benefit but increase complexity.

📊 Minimum Price Precision Enhancements

A broader set of markets will see improvements in price granularity, allowing traders to place orders at tighter spreads. This benefits high-frequency traders, arbitrageurs, and those seeking better price discovery.

Perpetual Contracts – Increased Granularity

Spot Trading Pairs – Refined Pricing

Multiple spot pairs across BTC, ETH, USDT, and USDC quote assets are receiving enhanced precision. Notable updates include:

• ADA/BTC: From 0.00000001 → 0.000000001
• AKITA/USDT: From 0.0000000001 → 0.00000000001
• BTT/USDT: From 0.000000001 → 0.0000000001
• ILV/USDT: From 0.1 → 0.01
• MILO/USDT & POLYDOGE/USDT: Now support up to 12 decimal places

These refinements enable more accurate pricing for micro-cap and highly volatile tokens, reducing slippage and improving fill rates.

⚠️ Risk Notice and Operational Impact

During precision adjustments:

• Assets with reduced quantity precision will experience a 2-minute trading suspension.
• Users cannot place or cancel orders, add margin, or transfer funds during this brief window.
• All other trading pairs remain unaffected.
• Markets with increased precision (more decimals) will operate without interruption.

🧾 Order and Position Handling Rules

1. Trading Quantity Precision Changes

A. Precision Reduced (Fewer Decimals)

When quantity steps become coarser (e.g., from 4 to 2 decimals):

• Limit Orders:

  • Orders with precision greater than the new standard will be cancelled.
    Example: An order for 8.0033 BTC when the new step is 0.01 → cancelled.
  • Orders within the new precision are preserved.

• Strategy Orders:

  • Grid & Martingale strategies (Spot Grid, Contract Grid, etc.) will have open orders cancelled and strategies terminated.
  • Other strategies (DCA, Iceberg, Stop-Loss, etc.) continue post-adjustment using updated precision.

B. Precision Increased (More Decimals)

All existing orders remain valid. No action required.

✅ API Users: The system will automatically truncate order quantities or prices submitted with outdated precision, allowing successful execution even if old formats are used.

2. Minimum Price Precision Changes

A. Price Precision Reduced (Larger Increments)

When price steps increase (e.g., from ±$5 to ±$1):

• Orders with finer-than-allowed prices are cancelled.
• Example: A limit buy at $137.456 under a new $137.46 minimum tick → cancelled.
• Grid and Martingale strategies using such orders are terminated.
• Other strategy types resume after adjustment with compliant pricing.

B. Price Precision Increased (Smaller Increments)

No disruption—existing orders remain active.

✅ API Users: Orders submitted with old price formats are auto-truncated to fit new rules.

📋 Historical Data Display Logic

User interface behavior differs slightly between platforms:

This ensures consistency for retail traders while preserving raw data fidelity for algorithmic systems.

💡 Why These Changes Matter

Precision tuning plays a critical role in modern crypto trading:

• Improved Liquidity: Finer pricing allows tighter bid-ask spreads.
• Better Execution: Traders gain control over entry and exit points.
• Reduced Noise: Removing unnecessary decimals simplifies trading for illiquid assets.
• Platform Scalability: Streamlined data models enhance performance during high volatility.

These updates align with industry best practices and reflect OKX's dedication to delivering a professional-grade trading environment.

❓ Frequently Asked Questions (FAQ)

Q: Will my open positions be liquidated due to these changes?

No. Open positions are not affected by precision adjustments unless associated limit or strategy orders are cancelled. Your margin and position size remain intact.

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

Yes—if your grid bot uses price or quantity steps that exceed the new limits, it will be terminated. You’ll need to recreate the strategy using updated precision settings after the change.

Q: Are leveraged tokens or savings products impacted?

No. These adjustments apply only to spot, margin, and perpetual contract trading pairs. Leveraged tokens, DeFi staking, and savings accounts are unaffected.

Q: How can I check the new precision for my trading pair?

Visit the trading interface or use the OKX API endpoint /api/v5/public/instruments to retrieve real-time precision data for all instruments.

Q: What happens if I submit an order during the 2-minute pause?

Orders cannot be placed during the suspension window. Attempted submissions will return an error. Trading resumes automatically after adjustment.

Q: Will there be future adjustments?

Yes. OKX continuously monitors market dynamics and may adjust precision parameters periodically to maintain optimal trading conditions.

Final Notes

Users trading affected pairs should review their active orders and automated strategies ahead of the update window. While most changes enhance functionality, reductions in precision require proactive management to avoid unintended order cancellations.

OKX remains committed to building a responsive, secure, and efficient trading ecosystem—empowering both retail and institutional traders worldwide.
