In order to boost market liquidity and improve trading experience, OKX will be adjusting the tick sizes for various pairs in the spot / margin trading markets between 14:00–14:30 am UTC on Jul. 29, 2022.
Note: If a pair is tradable in both spot and margin markets, the adjustment will be applicable to both.
Specific adjustment details are as follows:
Existing orders will not be canceled because of the adjustment, and users should take note of the following:
1. Open orders and historic orders will be displayed with the adjusted tick sizes by rounding down the buy orders and rounding up the sell orders.
2. After the adjustment, existing orders, including those placed by API users, will still be filled according to the original tick sizes.
For example, if a tick size is adjusted to 0.01 from 0.0001, an order originally placed at the price of 130.2442 will be displayed as 130.24 but will still be filled at 130.2442.
3. After the adjustment, if an API user places an order using the older, pre-adjustment tick size, the order still can be filled, as the system will automatically adjust the tick size to be consistent with the new one. As for non-API users, they can no longer use an older tick size after the adjustment.
Users are encouraged to adjust their trading strategies based on the changes highlighted above.
