SENSEX options historical data at 1-minute resolution

Options Data (optionsdata.shop) sells BSE SENSEX option-chain history at 1-minute resolution from NOV 2023 (where its SENSEX options archive begins) to SEP 2026 — every strike and expiry, calls and puts, with OHLC and volume — plus SENSEX 1-second option bars for MAY 2024 → DEC 2025. SENSEX options 1-min: open interest is present 7 Nov 2023 – 20 Apr 2026 and 6 Jul – 14 Aug 2026; it is 0 from 21 Apr – 3 Jul 2026 and from 17 Aug 2026. SENSEX 1-second option files have OI = 0 throughout. Files are Parquet, bought once by UPI; the SENSEX Options pack covers AUG 2023 → AUG 2026, with SENSEX data starting NOV 2023.

Why SENSEX options history is harder to find

Most free option datasets are NSE-first. BSE relaunched SENSEX weekly options in 2023, so there is less history in total, and broker APIs expose BSE derivatives less consistently than NSE.

The Options Data archive holds SENSEX 1-minute option chains for 715 trading days (NOV 2023 → SEP 2026). SENSEX futures 1-minute run NOV 2023 → SEP 2026 and SENSEX spot 1-minute JAN 2023 → SEP 2026.

Things to know before you load it

Two column layouts exist. Files from 7 Nov 2023 to 14 Aug 2026 use layout B (timestamp, open, high, low, close, volume, oi, strike, option_type, expiry, iv — iv is taken as-is from the data feed, not independently verified). Files from 17 Aug 2026 and the 1-second files use layout A, where the underlying is BSESEN in stock_code and the exchange BFO in exchange_code.

SENSEX options 1-min: open interest is present 7 Nov 2023 – 20 Apr 2026 and 6 Jul – 14 Aug 2026; it is 0 from 21 Apr – 3 Jul 2026 and from 17 Aug 2026. SENSEX 1-second option files have OI = 0 throughout.

Every row carries its own expiry (expiry_date or expiry), so changes to the weekly expiry weekday over the years are handled by the data rather than by a calendar assumption in your code.

For second-level work, SENSEX 1-second chains exist for MAY 2024 → DEC 2025 only; outside that window, 1-minute is the finest resolution held.

import pandas as pd
df = pd.read_parquet("SENSEX_OPT_1min_2026-09-24_exp2026-10-01.parquet")   # layout A
print(df["stock_code"].unique(), df["exchange_code"].unique())   # ['BSESEN'] ['BFO']
# for older layout B files, apply the rename from /free/schema first
calls = df[df["right"] == "Call"]
print(calls.groupby("strike_price")["volume"].sum().nlargest(5))

Does SENSEX data include IV or Greeks?

No Greeks and no bid/ask. SENSEX 1-minute option files from 7 Nov 2023 to 14 Aug 2026 include an iv column taken as-is from the data feed (not independently computed or verified); files from 17 Aug 2026 and the 1-second files have no iv column.

The free sample is three NIFTY options days (15–17 Sep 2026). It has 13 columns (layout A), which matches SENSEX files from 17 Aug 2026 (stock_code BSESEN, exchange_code BFO). Older SENSEX 1-minute files use layout B and include iv — see /free/schema.
