To enhance market liquidity and improve user trading experience, OKX will adjust the minimum price precision and trading quantity precision for select spot/margin and perpetual contract trading pairs on August 24, 2023, from 2:00 PM to 4:00 PM (UTC+8).
This update affects specific digital asset pairs across spot, margin, and derivatives markets. Users are advised to review the changes carefully to ensure their trading strategies, open orders, and automated systems remain compliant post-adjustment.

Updated Trading Quantity Precision
Trading quantity precision refers to the smallest increment by which a trade size can be specified (e.g., 0.001 BTC or 10.0001 USDT). Adjusting this value impacts order placement, strategy execution, and system handling of existing positions.
The following pairs will undergo a reduction in trading quantity precision, meaning the smallest allowed trade size will increase (e.g., from 0.000001 to 0.00001). During the adjustment window, these pairs will be temporarily suspended for 2 minutes to ensure a smooth transition:
- EM/USDT: From
0.000001→0.00001(Pause: 2:01–2:03 PM) - DOME/USDT: From
0.000001→0.00001(Pause: 2:04–2:06 PM) - DEP/USDT: From
0.000001→0.00001(Pause: 2:07–2:09 PM) - SPELL/USDT: From
0.000001→0.00001(Pause: 2:10–2:12 PM)
⚠️ Note: Only pairs with reduced precision will face brief downtime. All other markets remain unaffected during this maintenance window.
Users holding open orders or active strategies on these pairs should expect automatic cancellations if order parameters no longer meet new precision rules.
Adjusted Minimum Price Precision
Price precision determines how finely prices can be quoted (e.g., $1.2345 vs $1.23). Increasing precision allows tighter spreads and more granular pricing—beneficial for high-frequency traders and arbitrageurs.
The following pairs will see changes in minimum price tick size, affecting both spot and perpetual contracts:
Perpetual Contracts
- AIDOGE/USDT:
0.000000000001→0.0000000000001 - TON/USDT:
0.001→0.0001 - SOL/USD:
0.01→0.001 - BAND/USDT:
0.001→0.0001 - AVAX/USD, AVAX/USDT:
0.01→0.001 - ALPHA/USDT, ALGO/USD, ALGO/USDT:
0.0001→0.00001
Spot & Margin Pairs
- AIDOGE/USDT: Same ultra-fine adjustment as above
- TON/USDC, BAND/USDT, AVAX/USDC, etc.: Various reductions in tick size
Notable increases in precision include:
- ZBC/USDT, AZY/USDT, DGB/USDT, OMN/USDT, RADAR/USDT: From
0.00001→0.000001 - PLS/USDT, TURBO/USDT, RACA/USDT: From
0.0000001→0.00000001 - GM/USDT: From
0.00000001→0.000000001
- ZBC/USDT, AZY/USDT, DGB/USDT, OMN/USDT, RADAR/USDT: From
These updates allow traders to place more competitive bids and offers, especially in volatile or low-spread environments.

Risk Notice and Operational Impact
During precision adjustments:
- Assets with reduced quantity or price precision will be paused for approximately 2 minutes.
- No trading operations—including placing orders, canceling trades, adding margin, or transferring funds—are allowed during this short downtime.
- All other trading pairs continue uninterrupted.
This temporary suspension ensures data consistency and prevents execution errors during backend recalibration.
Order and Position Handling Rules
1. Trading Quantity Precision Changes
When Precision Is Reduced (e.g., from 4 decimals to 2)
| Scenario | Action |
|---|---|
| Limit Order quantity exceeds new precision | ❌ Automatically canceled |
| Limit Order quantity within new limits | âś… Remains active |
Example:
An order for 8.123456 units under old ± 6 decimals rule would be invalid if new limit is ± 4 decimals. The system cancels it.
Strategy Orders Affected Differently:
- Grid & Martingale Strategies (Spot Grid, Contract Grid, etc.)
→ If any grid level violates new precision, the entire strategy stops. - Other Strategies (DCA, Iceberg, Stop-Loss, etc.)
→ Open orders canceled due to precision mismatch, but the strategy itself continues and resumes with updated rules after trading resumes.
💡 API traders: The system will automatically truncate order quantities to fit new precision if submitted with outdated formats—your order may still go through even with old decimal input.
Web/Mobile Users:
Cannot submit orders using deprecated precision settings—they must align with updated standards.
2. Price Precision Changes
When Price Steps Increase (e.g., from $1.2345 → $1.23)
| Scenario | Action |
|---|---|
| Limit Order price has finer granularity than allowed | ❌ Canceled |
| Limit Order uses coarser or equal step size | âś… Preserved |
Example:
A buy order at $54.321 when the new minimum step is $54.33 will be rejected if finer pricing is no longer permitted.
Strategy Impacts:
Same as above—grid-based strategies terminate upon invalid levels; others resume post-adjustment.
đź’ˇ API traders again benefit from truncation logic: submitting a price like54.3216when only two decimals are allowed results in automatic rounding down to54.32.
Historical Data Display Rules
After adjustment:
Web & Mobile Users: Historical trades and positions reflect the new precision standard.
- Buy orders: Rounded down ("truncated")
- Sell orders: Rounded up ("ceiling")
- API Users: Maintain original precision in historical records—no rounding applied retroactively.
This ensures backward compatibility for algorithmic systems relying on exact historical values.
Key Takeaways for Traders
Understanding these changes helps prevent unintended order cancellations or strategy failures:
- Monitor affected pairs closely before August 24.
- Update trading bots and scripts with new precision values.
- Reconfigure grid strategies manually if needed after resumption.
- Leverage increased price granularity for better entry/exit control.
