OKX to change funding fee collection mechanism for some contracts
To provide you with better services, OKX will change the funding fee collection mechanism for some perpetual contracts from cross-period collection to current-period collection.
Before the change:
Formerly, funding fee calculations were based on the funding rate of the previous funding period (cross-period collection).
For example, when the funding fee is collected every 8 hours, funding fee calculations at 8:00 am UTC+8 today use the funding rate determined by the premium index from 4:00 pm UTC+8 yesterday to 12:00 am UTC+8 today, resulting in a fixed value from 12:00 am UTC+8 to 8:00 am UTC+8.
After the change:
Funding fee calculations will be based on the funding rate of the current funding period (current-period collection).
For example, funding fee calculations at 8:00 am UTC+8 every day will use the funding rate determined by the premium index from 12:00 am UTC+8 to 8:00 am UTC+8. Note that the funding rate may fluctuate before the funding fee is collected, so you need to dynamically manage your positions according to current conditions.
Affected contracts:
Date and time: January 4, 2024, 12:00 am UTC+8
USDT-margined perpetual contracts: FLOWUSDT
Date and time: January 10, 2024, 12:00 am UTC+8
USDT-margined perpetual contracts: SOLUSDT, TRBUSDT, XRPUSDT, BCHUSDT, and WLDUSDT
Other perpetual contracts will change based on market conditions, with separately issued announcements.
Funding fee collection before and after the first change:
| Funding fee collection | Premium index period used for funding rate calculations | 
|---|---|
| January 3, 2024, 4:00 pm UTC+8 | January 3, 2024, 12:00 am UTC+8 - January 3, 2024, 8:00 am UTC+8 (cross-period collection) | 
| January 4, 2024, 12:00 am UTC+8 | January 3, 2024, 4:00 pm UTC+8 - January 4, 2024, 12:00 am UTC+8 (current-period collection) | 
| January 4, 2024, 8:00 am UTC+8 | January 4, 2024, 12:00 am UTC+8 - January 4, 2024, 8:00 am UTC+8 (current-period collection) | 
| January 4, 2024, 4:00 pm UTC+8 | January 4, 2024, 8:00 am UTC+8 - January 4, 2024, 4:00 pm UTC+8 (current-period collection) The same collection mechanism will be applied moving forward. | 
API changes:
The main changes include additional methods for determining the difference between current-period collection and cross-period collection in the APIs for funding rates and funding rate history. Furthermore, nextFundingRate will return a null value for contracts using current-period collection. The following link provides more details: https://www.okx.com/docs-v5/log_en/#2023-12-20
In addition, OKX will closely monitor market changes for altcoins with a significantly fluctuating premium index. When necessary, funding fee collection may change from every 8 hours to every 6 hours, 4 hours, 2 hours, or 1 hour. Details will be announced separately.
Friendly reminders:
- These changes may affect your trading strategies. Therefore, based on market trends, you can close your USDT perpetual positions before each collection time to avoid funding fee charges. 
- The lighting icon will be displayed next to the funding rate of contracts that have changed to current-period collection.
