India’s stock market splits into three end-of-day timelines from Monday, changing both when different securities stop trading and how the closing prices of stocks with futures and options (F&O) contracts are determined.
Continuous trading in F&O-linked stocks will end at 3:15 p.m. before they move into a Closing Auction Session, or CAS. Other stocks will continue trading until 3:30 p.m., while index and stock derivatives will remain open until 3:40 p.m.
