BSE introduces pre-open session for index, stock futures
The Bombay Stock Exchange (BSE) is adding a pre-open trading session for index and stock futures starting December 8, 2025.
This update brings the same 15-minute head start that stocks already get, aiming to make opening prices fairer and less jumpy.
Why does this matter?
If you follow or trade in index and stock futures, this means fewer wild swings when the market opens—especially after big overnight news.
Pre-open sessions help everyone adjust to fresh info before real trading kicks in, making things smoother and more transparent.
Testing the waters
BSE will test the new system from October 6, 2025, so brokers and tech teams can get ready.
Everything's being built on existing tech to keep things simple.
More details are coming soon in an official circular.
