CoinFeed reported on May 5th that Binance has released a significant update to its commodity-based TradFi perpetual contract price index calculation model. Starting May 9th, 2026 at 05:00 (UTC+8), Binance will adopt the EWMA (Early Wage Margin) price index calculation model to replace the fixed model used for calculating the price index of commodity-based TradFi perpetual contracts during daily maintenance, holidays, and weekends. The EWMA price index calculation model will be applied to all commodity-based TradFi perpetual contracts, including XAUUSDT, XAGUSDT, XPTUSDT, XPDUSDT, COPPERUSDT, CLUSDT, BZUSDT, NATGASUSDT, and future commodity-based TradFi perpetual contracts to be listed on Binance Futures.
