Common questions
Why can an NSE lot size change?
NSE reviews contract lot sizes and can revise them when contract value requirements or exchange rules change. New contracts may use a revised lot size while older expiries can follow their existing specification.
Is this list the final authority for trading?
No. This is a static reference snapshot. The latest NSE_FO_contract_ddmmyyyy.csv.gz contract file and exchange circulars are authoritative for a specific contract and expiry.
Does lot size equal margin?
No. Lot size is the number of units in one derivatives contract. Margin depends on the instrument, price, expiry, volatility, broker and exchange risk parameters.
