Binance will end the BULLA perpetual contract latest price protection period.

Binance Futures will end the latest-price protection period for its BULLAUSDT USDⓈ-margined perpetual contract at 20:30 Beijing time on November 10, with the mark price gradually transitioning to standard calculation methods over a period of up to three hours. During the transition, the funding rate cap and floor will widen from ±0.005% to ±2%, and the settlement interval will shorten from four hours to one hour whenever the previous funding rate settlement reaches ±2%. Trading remains unaffected during the transition, and existing orders and positions will not be canceled. The change matters because it shifts BULLA pricing from a protected regime to standard mark-price mechanics while sharply expanding funding-rate volatility limits. Traders should watch the mark-price convergence over the three-hour window and the first funding settlements under the new ±2% cap for signs of positioning stress.
