Methodology
Historical chain notes
One published session
Rows come from NSE's F&O Bhavcopy archive for the selected date and expiry. Previous and next move one weekday at a time; a market holiday can have no publication.
Close provenance
A dotted close means that contract did not trade that session. Its last traded close was carried forward; it is not a fresh trade.
Settlement
Settlement is NSE's official daily mark only where Bhavcopy publishes it. On a contract's own expiry day the column has a different meaning, called out above.
