NIFTY OPTION CHAIN ANALYTICS
Nakshatra — NIFTY Option Chain Analytics
A free, self-hosted NIFTY option-chain tool that captures the full chain every five minutes — so you can read how positioning builds through the day, not just where it landed. See data. Spot opportunity. Trade smart.
What you get
-
5-minute option-chain history
Most tools show one frozen snapshot. Nakshatra stores the full NIFTY chain every five minutes through the session, so you can scrub back through the day and watch OI, IV, and premiums actually build.
-
Insights verdict engine
A plain-English read on the day's positioning — PCR, OI shift, the ATM straddle's expected move, and how max pain drifts against spot, distilled into one composite verdict.
-
OI cohort-exit inference
Knowing OI fell is half the story. Nakshatra groups buildup into daily cohorts and infers whether each drop is short covering or long liquidation using the delta-adjusted premium move — so you see who is unwinding.
-
FII/DII activity
Daily foreign and domestic institutional flows alongside the chain, for the directional context the option data alone can't give you.
-
One-click Excel export
Export the currently visible columns of any snapshot to a named .xlsx file — take the raw chain into your own spreadsheet whenever you need it.
