Market Hours
Indian stock markets operate within fixed trading sessions. The equity segment trades from 9:15 AM to 3:30 PM IST, Monday to Friday — knowing these windows matters for integrations, since live market data and order placement are only available while a segment is in session.

- Muhurat trading — a special one-hour session held on Diwali; timings are announced by the exchanges each year.

- Special/mock sessions — exchanges occasionally announce shortened, extended, or mock trading sessions by circular.
Note: For API integrations
Outside market hours, streaming subscriptions succeed but deliver no live ticks; snapshot subscriptions return the last available data. Check marketStatus per exchange segment rather than hard-coding session times, since exchanges revise timings by circular.
