NIFTY Options Historical Data (1-Minute, Full Chain)

Yes. Every row carries open_interest for that strike and side at that minute, alongside open, high, low, close and volume. This is the main thing the free NIFTY datasets do not have — most of them are OHLCV-only.

All of them. For every trading day in your range you get every strike on both calls and puts, for every expiry that was live on that day — weekly and monthly. Free dumps generally carry only the nearest expiry.

Option chains are delivered as Parquet, and continuous series as CSV. Both are readable by pandas in one line. Column names and dtypes are listed on the file schema page.

As fixed one-time packs, not a subscription: the last 3 months (₹1,499), a single calendar year (₹2,999), the 3-year options pack (₹7,249) or NIFTY Complete with futures and spot (₹7,999). No annual licence and no GST added.

No. The licence is for your own research, backtesting and internal use. Redistribution, resale and republishing the raw files are not permitted — see the terms page.

This archive's continuous NIFTY 1-minute options series starts in January 2023 (a handful of June 2021 sessions also exist but are not a continuous series). We only sell what we hold; the coverage table above shows the real first date.

OHLC, volume, open interest and contract fields (expiry, strike, call/put). Files from Jul 2023 to 14 Aug 2026 also include an iv column taken as-is from the data feed; it is not independently computed or verified. No Greeks, no bid/ask. Column names follow two layouts — see the file schema page.

UPI. You place the order, pay the exact amount to the UPI ID shown on the order page, submit the UTR reference, and the download link is issued once payment is confirmed.
