Closing auction

The NSE/BSE closing session helps determine the official closing price used for indices and mutual fund NAVs in India.

Indian exchanges run an end-of-day closing mechanism whose timings are exchange-notified.

Official closes feed index calculation, mutual fund NAVs, and mark-to-market processes.

Large passive funds often concentrate liquidity around the close.

Related discovery windows include the pre-open session and other call auctions.
