To enhance market liquidity and improve the overall trading environment, OKX will implement adjustments to the tick sizes for a number of spot, margin, and perpetual futures trading pairs. This update is scheduled to occur between 6:00 am and 10:00 am UTC on April 30, 2025.
During this maintenance window, specific trading pairs will experience a brief, two-minute trading suspension to facilitate a seamless transition. It is crucial for traders to understand how these modifications may impact their open orders, trading bots, and overall strategy.
Detailed Schedule of Tick Size Adjustments
The following table outlines the specific trading pairs affected, their current and new tick sizes, and the exact two-minute windows during which trading will be temporarily halted.

Understanding the Impact on Your Orders and Positions
The effect on your open orders depends entirely on the direction of the tick size change.
For Open Orders and Trading Bots
1. Adjustments to Fewer Decimal Places (e.g., 0.0001 to 0.01)
This type of change, which makes the tick size larger, will trigger a temporary trading suspension and affect existing orders.
Limit Orders: Any open limit order with a price that contains more decimal places than the new tick size will be automatically canceled. Orders with prices at or within the new tick size will remain open.
- Example: If the tick size changes from 0.0001 to 0.01, an order at 130.2442 will be canceled, while an order at 130.2400 will not.
Trading Bots: The same logic applies to orders placed by bots. However, the handling of the bots themselves varies:
- Grid & DCA Bots: All open orders from these bots will be canceled, and the bots themselves will be stopped. This includes Spot Grid, Futures Grid, Moon Grid, Infinity Grid, Spot DCA, and Futures DCA.
- Other Bots: Open orders from all other bot types (e.g., Signal Bot, Recurring Buy, TWAP, Iceberg) will be canceled, but the bots will not be stopped. They will simply resume trading using the new tick size once the market reopens.
2. Adjustments to More Decimal Places (e.g., 0.01 to 0.0001)
This type of change, which makes the tick size smaller, does not cause a trading halt. All open orders will simply be filled according to the new, more precise tick size.
Important Note for API Users: The above rules apply to API orders as well. Furthermore, if you attempt to place an order using the old tick size via API after the adjustment, the system will automatically round the price (down for buys, up for sells) to conform to the new standard. This automatic rounding is not available on the standard web and mobile interfaces.
Order Display in Your History
How your order history appears will also change based on the adjustment type.
- Adjustments to Fewer Decimal Places: For most users, the display of both open and historical orders will be adjusted to the new tick size. API users will see the original, pre-adjustment prices in their display.
- Adjustments to More Decimal Places: All orders will continue to be displayed using their original tick size.
Traders are strongly advised to review their active strategies and open positions in light of these changes to ensure continued alignment with their goals. For executing advanced trading strategies under the new parameters, you can explore more strategies on the official platform.
Risk Management During the Update
A critical risk warning pertains to the two-minute trading suspensions for pairs moving to a larger tick size. During this brief window, you will be unable to transfer funds, place new orders, or cancel or modify existing orders for the affected pairs. This suspension does not apply to any other trading pairs on the platform.
All traders should be aware that digital asset markets are highly volatile and speculative. It is every investor's responsibility to conduct their own research (DYOR) and understand their personal risk tolerance before engaging in any trading activity.

Frequently Asked Questions
Q1: What is a tick size, and why is it important?
A tick size is the minimum price movement increment a trading pair can make. It is a fundamental market structure parameter that affects liquidity, spreads, and the execution of orders. Adjustments are made to optimize the trading experience for all users.
Q2: Will my stop-loss or take-profit orders be affected?
Yes, any conditional order (including stop-loss, take-profit, and trailing stop orders) for a pair undergoing a tick size adjustment to fewer decimal places will be canceled during the two-minute suspension. You will need to reset these orders after trading resumes using the new tick size.
Q3: I use trading bots. What should I do to prepare?
If you are running any Grid or DCA bots on the affected pairs, be aware they will be stopped and their orders canceled. You will need to restart them manually after the update. For all other bot types, they will pause briefly and restart automatically.
Q4: Is my funds' safety compromised during this update?
No. The adjustment is a routine technical update. Your funds and positions remain secure in your account throughout the process. The temporary suspension only affects the ability to create new orders or modify existing ones for a very short period.
