To enhance market liquidity and improve the overall trading experience, the exchange will implement adjustments to the minimum price increment, also known as the tick size, for a selection of spot trading pairs. These changes are scheduled to occur between 2:00 PM and 6:00 PM (UTC+8) on June 10, 2025.
This guide provides a comprehensive overview of the adjustments, their impact on trading activities, and the necessary steps traders should consider.
Detailed Adjustment Schedule
The tick size modifications are categorized into two types: those requiring a brief trading halt and those proceeding without interruption.
Adjustments with a Trading Halt
For pairs where the tick size is being decreased, trading will be temporarily suspended for exactly two minutes to facilitate a smooth transition. During this window, all order activities—including placing new orders, canceling existing ones, margin top-ups, and fund transfers—will be paused for the affected pair.
| Trading Segment | Trading Pair | Previous Tick Size | New Tick Size | Adjustment Window (UTC+8) |
|---|---|---|---|---|
| Spot | ETH-TRY | 0.1 | 1 | 3:01:00 PM - 3:02:59 PM |
| Spot | SOL-AED | 0.01 | 0.1 | 3:03:00 PM - 3:04:59 PM |
| Spot | XRP-AED | 0.0001 | 0.001 | 3:05:00 PM - 3:06:59 PM |
Adjustments Without a Trading Halt
For pairs where the tick size is being increased, trading will continue uninterrupted throughout the adjustment process.
| Trading Segment | Trading Pair | Previous Tick Size | New Tick Size |
|---|---|---|---|
| Spot | DEP-USD | 0.000001 | 0.0000001 |
Important Considerations for Traders
Understanding the implications of these changes is crucial for managing your open positions and orders effectively.
Order Handling Rules
The treatment of your existing orders depends entirely on the direction of the tick size change.
For a Decreasing Tick Size (e.g., 0.0001 to 0.01):
Limit Orders: Any active limit order with a price precision that is greater than the new tick size will be automatically canceled. Orders with a price precision less than or equal to the new standard will remain open.
- Example: If the new tick size is
0.01, an order priced at130.2442will be canceled, while an order priced at130.2400will remain active.
- Example: If the new tick size is
Strategy Orders: The same precision rule applies to all advanced strategy orders (e.g., Stop-Loss, Take-Profit, TWAP). However, the consequence of cancellation varies by strategy type:
- Grid & Martingale Strategies: This includes Spot Grid, Futures Grid, Infinity Grid, and Martingale strategies. If any order within these strategies is canceled due to the tick size change, the entire strategy will be terminated.
- Other Strategies: This includes DCA, Iceberg, Arbitrage, and Signal strategies. If an order is canceled, the strategy itself will not be terminated. It will simply place new orders using the updated tick size once trading resumes.
For an Increasing Tick Size (e.g., 0.01 to 0.0001):
- All existing open orders for the affected pair will remain completely unaffected.
Note for API Users: The above rules apply universally. However, post-adjustment, if an API user submits an order using the old tick size, the system will automatically truncate the price to fit the new precision, and the order will be placed successfully. Web and App users do not have this functionality and must use the new tick size.
Display Rules for Positions and Order History
How your portfolio and history are displayed will also change.
- Decreasing Tick Size: On Web and App interfaces, the display price for existing positions and historical orders will be adjusted to the new precision. The principle applied is: existing buy orders are truncated, and existing sell orders are rounded up. API users will continue to see the original precision.
- Increasing Tick Size: All displays will maintain the original precision without any changes.

Frequently Asked Questions
What is a tick size or minimum price increment?
The tick size is the smallest allowable price movement for a trading pair. It determines the minimum difference between bid and ask prices. For example, if a pair has a tick size of 0.01, you can place an order at 100.00 or 100.01, but not at 100.005.
Why is the exchange making these changes?
These adjustments are made to improve market liquidity and create a more efficient trading environment for all users. Optimizing tick sizes can lead to tighter spreads and better price discovery.
Will my funds be at risk during the two-minute halt?
No. The trading halt only pauses the ability to place or cancel orders for a specific pair. All your existing holdings and account balances remain safe and secure. The halt is a standard procedural measure to ensure a clean transition.
What should I do before the adjustment time?
It is highly recommended that you review any open orders, especially limit and strategy orders, on the affected pairs. For pairs with a decreasing tick size, consider if your orders will be canceled and plan accordingly. For complex strategies like Grids, be aware of the risk of full termination.
As an API user, do I need to update my code?
While the system will handle price truncation, it is a best practice to update your trading algorithms to use the new tick sizes to ensure your orders behave exactly as intended after the update.
How can I stay informed about future announcements?
The best way to stay updated is to regularly check the exchange's official announcement page or enable relevant notification settings within your account. 👉 View real-time updates and tools
