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 .

A limit order rejected for being far from the LTP is a freak-trade safeguard: Zerodha blocks limit orders in stock and index options placed 50% to 150% away from the last traded price, and the exchange separately cancels orders outside a dynamic Price Reasonability Range , because an order priced far from the current market can execute at a level unrelated to fair value and distort price discovery. The fix is to price the order closer to the LTP, or to use a GTT order , which is exempt from the far-from-LTP block.
