NIFTY expiry sessions, 1-second bars, 2023 to date

One row per second for NIFTY: options + index, covering 2 Jan 2023 – 23 Oct 2026. Because the pack covers every trading day in its window, it contains every weekly and monthly expiry in that period plus the sessions leading up to each one.

One-second bars matter most in the last hour of an expiry session, when an option can double and halve inside a single minute. Use them to test entry and exit timing that one-minute bars blur.
