Adjusted Trading Quantity Precision
The following table outlines changes to the trading quantity precision for specific trading pairs. These adjustments will also apply to corresponding margin trading pairs where available.

Scheduled adjustment window: 14:00 – 14:02 (UTC+8) - YEE/USDT: Precision adjusted from
0.000001to0.0001
Scheduled adjustment window: 14:06 – 14:08 (UTC+8)
These updates mean that order quantities must now conform to the new precision levels. Orders failing to meet the updated standards may be automatically canceled during the transition.
Adjusted Minimum Price Precision
The minimum price precision for several trading pairs will also be refined, enabling tighter bid-ask spreads and greater pricing granularity.
- FIL/ETH: From
0.0001→0.000001
Time: 14:03 – 14:05 - YEE/USDT: From
0.000001→0.0000001

This increased precision allows traders to place orders at more competitive price points, supporting tighter market-making and improved execution.
Temporary Trading Suspension During Adjustment
To ensure system stability, trading for affected pairs will be paused for approximately two minutes during each precision update window. During this time:
- New orders cannot be placed
- Existing orders cannot be canceled
- Margin adjustments and fund transfers for the affected pair are suspended
All other trading pairs remain unaffected and fully operational. Traders are encouraged to manage open positions and pending orders in advance to minimize disruption.
Handling of Orders and Positions During Precision Changes
1. Trading Quantity Precision Adjustments
a) Precision Reduced (e.g., from 0.0001 → 0.01)
When the allowed quantity decimal places decrease:
Limit Orders: Orders with quantity precision exceeding the new limit will be canceled. For example:
- An order for
8.0001will be canceled. - An order for
8.01(within new limits) remains valid.
- An order for
Strategy Orders:
- Grid and Martingale strategies (e.g., spot grid, futures grid, dual-grid, spot Martingale): If active orders are canceled due to precision mismatch, the entire strategy will be terminated.
- Other strategies (e.g., dollar-cost averaging, time-weighted trading, iceberg orders, arbitrage, stop-loss/take-profit): Canceled orders will not stop the strategy; it will resume with updated precision once trading resumes.
b) Precision Increased (e.g., from 0.01 → 0.0001)
All existing orders remain valid and unaffected.
Note for API Users: If an API request uses pre-adjustment precision (e.g., placing an order with8.001234when only8.01is allowed), the system will automatically truncate the value to fit the new standard. Web and mobile users cannot submit such orders.
2. Display Rules for Historical Orders and Positions
a) Quantity Precision Reduced
- Web and mobile users will see historical order and position quantities rounded to the new precision.
- API users retain access to original precision in historical data.
b) Quantity Precision Increased
Historical data continues to display at original precision levels.
Price Precision Adjustment Rules
1. Price Precision Reduced (e.g., from 5 decimals → 2 decimals)
Limit Orders: Orders with price precision exceeding the new standard are canceled.
- Example: A bid at
130.2442would be canceled if only two decimals (130.24) are allowed.
- Example: A bid at
Strategy Orders:
- Grid and Martingale strategies are terminated if their orders are canceled.
- Other strategies survive cancellation and resume with updated price precision post-adjustment.
2. Price Precision Increased (e.g., from 2 → 5 decimals)
All existing orders remain valid and unaffected.
API User Note: Orders submitted via API with old price precision are automatically truncated to meet new standards and processed successfully.
Display of Historical Prices
When price precision is reduced:
Web and mobile interfaces display historical prices rounded according to new rules:
- Buy orders: Truncated (rounded down)
- Sell orders: Rounded up
- API users continue to see original price precision.
When price precision increases:
