Price Reasonability Range (PRR) and the execution range

Sun, 21 Jun 2026 00:00:00 +0000

The Price Reasonability Range (PRR), more often called the execution range, is a dynamic band that NSE and BSE set around a contract’s reference price, inside which an order is allowed to match and execute. It exists to prevent freak trades, fills that print far from the prevailing market because a fat-finger order or thin depth let a market order sweep through empty price levels. An order priced or matched outside the range is cancelled rather than executed. It is a market-microstructure control, not a Zerodha rule, and it is distinct from the daily price band .
