Important: Mark Price Calculation Update for POWRUSDT, MLNUSDT, DUCKUSDT, ALPHAUSDT, and NEIROUSDT(10-18)
Dear KuCoin Users,
To further enhance the accuracy and stability of the mark price mechanism, KuCoin Futures will upgrade the Mark Price calculation formula for selected contracts.
1. Contracts and Schedule
Contracts: POWRUSDT, MLNUSDT, DUCKUSDT, ALPHAUSDT, NEIROUSDT
Adjustment Time: 07:00–09:00 on October 18, 2025 (UTC)
During the transition, the Mark Price will be smoothly and gradually switched from the old formula to the new one. Trading and existing positions will not be affected.
More contracts will be adjusted in the following phases, and separate announcements will be published accordingly.
2. Details of the Formula Adjustment
Before:
Mark Price = Index Price + Moving Average of Basis
where Moving Average of Basis = Moving Average[(Best Ask + Best Bid)/2 – Index Price]
After:
Mark Price = Median(Price 1, Price 2, Contract Price)
-
Price 1 = Index Price × [1 + Latest Funding Rate × (Time Until Next Funding ÷ Funding Interval)]
-
Price 2 = Index Price + Moving Average of Basis
-
Contract Price = Latest Traded Price
The new median-based mechanism provides a more stable mark price during periods of extreme volatility, reducing liquidation risks and improving pricing fairness.
3. Risk Reminder
-
Due to the change in the Mark Price calculation method, the liquidation price of some positions may be slightly adjusted.
-
Please review your positions and margin levels in advance, and adjust leverage and exposure as appropriate.
-
For users running strategy trading or API integrations, please update your mark price logic to ensure proper functionality.
KuCoin Futures will continue to optimize its contract trading mechanisms to provide users with a safer and more efficient trading experience.
Thank you for your understanding and continued support!
