Crypto exchange Binance is implementing a new spot trading feature designed to prevent orders from executing outside a defined price range during periods of extreme market volatility.
The mechanism, called the Spot Price Range Execution Rule (PRER), will launch on April 14. It restricts trades to dynamic price bands around a reference price derived from recent trades.
Binance said PRER is intended to maintain fair and orderly markets during stress events when liquidity thins. The rule applies to taker orders-trades that execute against existing liquidity-and will not affect normal trading conditions.
Unlike user-set stop-loss or limit orders, PRER is an exchange-level protection tool that can cancel or restrict executions based on system-defined limits.
The feature does not eliminate slippage but aims to reduce extreme executions during volatile periods. PRER may not be available for all trading pairs and could adjust parameters based on market conditions.
This move follows concerns raised after a major market sell-off in October 2025, when some assets experienced depegging issues. Binance's co-founder Changpeng Zhao denied the exchange contributed to those events.
