What is F&O lot size?
Every NSE futures and options contract trades in fixed lot multiples. Order quantity must be a multiple of the lot size (for example, 75 for Nifty index futures after recent revisions).
Lot sizes change when NSE adjusts contract values to stay near regulatory notional targets—always confirm before expiry rolls.
