As part of its ongoing commitment to enhancing market liquidity and improving user trading experiences, OKX will adjust the minimum price precision for select spot and margin trading pairs on December 21, 2023, from 11:30 AM to 12:00 PM (UTC+8). This update ensures greater pricing flexibility and tighter spreads across supported markets.
All changes will be applied simultaneously to both spot and leveraged trading pairs where applicable. Below is a detailed overview of the upcoming adjustments and what users need to know.
🔧 Updated Price Precision for Selected Trading Pairs
The following table outlines the specific changes being implemented:
- ZEC/USDT: Minimum price precision adjusted from
0.01to0.001 - ZEC/USDC: Minimum price precision adjusted from
0.01to0.001
These refinements allow traders to place orders with finer granularity, supporting more precise entry and exit points—especially valuable in volatile or high-frequency trading environments.

⚠️ Temporary Trading Suspension During Adjustment
To ensure system stability during the transition:
- Pairs undergoing reduced precision (e.g., changing from
0.0001to0.01) will experience a temporary 2-minute trading suspension. - During this brief window, users cannot submit new orders, cancel existing ones, add margin, or transfer funds for the affected pairs.
- All other trading pairs remain fully operational.
Note: Pairs with increased precision (e.g., moving from 0.01 to 0.0001) will not face any trading interruptions.
đź“‹ Order Handling Rules During Precision Changes
1. When Price Precision Decreases (e.g., from 0.0001 → 0.01)
a. Limit Orders
- Any open limit order with a price containing more decimal places than the new minimum will be automatically canceled.
- Orders that comply with or fall within the new precision level remain active.
Example: An order priced at130.2442would be canceled under a new0.01precision rule, while an order at130.24would stay valid.
b. Strategy Orders
All strategy-based orders follow the same cancellation logic:
- If the strategy’s order price exceeds the new precision limit, it will be canceled.
- However, the impact on the strategy itself varies by type:
| Strategy Type | Outcome After Cancellation |
|---|---|
| Grid & Martingale strategies (including spot grids, contract grids, infinite grids, dual grids, spot Martingale, contract Martingale) | The entire strategy will be terminated if any associated order is canceled. |
| Other strategies (e.g., time-weighted average price, iceberg orders, stop-loss/take-profit, trailing stop, arbitrage, signal-based trading, dollar-cost averaging) | The strategy remains active and will re-submit orders based on the updated price precision once trading resumes. |

2. When Price Precision Increases (e.g., from 0.01 → 0.0001)
- All currently open orders—regardless of their original precision—are fully preserved.
- No action is required from users; all orders continue as normal without interruption.
This ensures smooth transitions when moving toward finer pricing control.
đź’» API User Considerations
API traders are subject to the same cancellation rules as web and mobile users. However, there is one key difference:
If an API user submits an order using pre-adjustment price precision, the system will automatically truncate the price to match the new standard, allowing the order to go through successfully.
In contrast, web and mobile users cannot submit orders using outdated precision levels—the interface will reject such inputs outright.
Developers are encouraged to update their systems accordingly to avoid unexpected truncation behavior.
đź“Š Display Rules for Positions and Historical Orders
How past trades and current positions appear depends on the direction of the precision change.
Case 1: Precision Decreases (e.g., from 0.0001 → 0.01)
Web and Mobile Users: Historical orders and open positions are displayed using the new, coarser precision.
- Buy orders: Prices are truncated (rounded down) to fit the new format.
- Sell orders: Prices are rounded up to maintain conservative valuation.
- API Users: Continue to see data in original precision, preserving accuracy for programmatic analysis.
Case 2: Precision Increases (e.g., from 0.01 → 0.0001)
- No visual changes occur—historical data continues to display at the original precision level.
- New orders benefit from enhanced detail, but legacy records retain their formatting.
