Binance Futures will end the latest price protection (LPP) cycle for the ONEUSDT USDT-margined perpetual contract at 22:00 on Sept. 17, 2026, Beijing time, then gradually switch to standard mark-price calculations. The transition may last up to three hours, depending on market volatility and index-price stability. During the changeover, Binance will use mark-price smoothing to limit the effect of abrupt price moves. Trading will continue normally, and unfilled orders and positions will not be canceled.
