Fellow Binancians,
Binance constantly reviews its product and service offerings to ensure the best user experience for all users. Effective from 2026-05-08 21:00 (UTC), Binance will introduce Orderbook EWMA price index calculation mode on commodity-based TradFi perpetual contracts to replace Fixed Mode during the daily maintenance period, weekends, and holidays.
Notes:
Orderbook EWMA price index calculation mode will be applied on all commodity-based TradFi perpetual contracts, such as XAUUSDT, XAGUSDT, XPTUSDT, XPDUSDT, COPPERUSDT, CLUSDT, BZUSDT, NATGASUSDT, and any new commodity-based TradFi perpetual contracts to be listed on Binance Futures in the future.
Fixed Mode is applied on equity-based TradFi perpetual contracts during the daily maintenance period, weekends, and holidays until further notice. A separate announcement will be made if Binance decides to apply Orderbook EWMA price index calculation mode on equity-based TradFi perpetual contracts.
