According to Binance's official announcement, to prevent user orders from executing at abnormal prices during extreme market conditions, Binance will gradually implement a spot price range protection mechanism (PRER) starting April 14, 2026. This mechanism restricts orders to be executed only within a dynamic price range, thereby preventing significant price deviations caused by abnormal activities. Under this mechanism, all order types with execution prices outside the specified range (i.e., "eating order" types) will be canceled, while already executed portions will be settled as usual. The official statement indicates that under normal market prices, this mechanism will not affect daily trading.
