To prevent user orders from being executed at abnormal prices under extreme market conditions, Binance is introducing a feature that allows order execution only within a dynamic price range.

Starting April 14, 2026, the Spot Price Range Execution Rule (PRER) will be gradually introduced.

This mechanism restricts orders to execute only against liquidity priced within these ranges, preventing executions when prices deviate significantly due to abnormal activity. Under normal market prices, this mechanism will not affect daily transactions.

Where available, trading pairs may have a reference price, which is calculated based on recent trade prices in the market. Where a reference price is available, price bands may be set as configurable percentages above and below this reference price. When you place an order, it will execute against available liquidity within the allowed price range.

If your order would execute against liquidity outside the price bands when taking, the remaining unfilled portion of the order will expire and will not rest on the order book.
