Mumbai, Aug 28
The Bombay Stock Exchange (BSE) on Thursday announced that it plans to introduce a pre-opening session for futures and options (F&O) trading, starting December 8.
"It is proposed to introduce Pre-Open Session for index & stock futures in the Equity Derivatives Segment from Monday, December 08, 2025 onwards," BSE said in a circular.
Trading members are requested to note that there shall be no new changes in the Enhanced Trading Interface (ETI) API or market data broadcast streams to facilitate the roll-out of the said functionality, the exchange added.
BSE clarified that while it already offers pre-opening trading in the equity segment, the same message structures and field definitions will now apply to equity derivatives as well.
A mock testing of the pre-open session in the equity derivatives segment is scheduled for October 6, 2025, the stock exchange stated.
However, SEBI has already revised the number of expiries and adjusted lot sizes in an effort to reduce risks, which has also made derivatives trading relatively more expensive.
The SEBI chairman also said that the regulatory body, in collaboration with the Ministry of Corporate Affairs and stock exchanges, will soon launch a regulated platform that will provide reliable information on unlisted companies preparing to go public.
