How to download NIFTY option data: 1-minute or 1-second, Parquet or CSV

To download NIFTY option data, choose a timeframe, check the free sample, then buy a pack on Options Data (optionsdata.shop) and download the files from the link on your order page. NIFTY option chains are held at 1-minute for JAN 2023 → NOV 2026 and at 1-second for JAN 2023 → OCT 2026, with every traded strike of the nearest expiries, calls and puts, open interest on every row, as Parquet or CSV files you keep. Start with the NIFTY options historical data page.

Step 1: decide what you are downloading

"NIFTY option data" can mean three different things, and the right download depends on which one your work needs:

The option chain at 1-minute. Every traded strike of the nearest expiries, calls and puts, one bar per contract per minute, from JAN 2023. This is the default for intraday strategy research, straddles, spreads and expiry-day studies. See the NIFTY option chain dataset.

The option chain at 1-second. Nearest expiries, strikes around the money, plus a NIFTY spot file per day on the same clock, from JAN 2023. Use it for entries and stops that a minute bar is too coarse to judge. See the NIFTY 1-second dataset.

Options with futures and spot. The Complete packs add NIFTY futures and the spot index at 1-minute, so the underlying and the chain share one clock.

Step 2: check the free sample

Before paying for anything, get the free sample by email, with your email and mobile number. It is real NIFTY option chain data at 1-minute (and a separate 1-second day), in the same Parquet layout as the paid files.

Open it in your own code and confirm the columns, the timestamps (IST, bar start, e.g. 09:15:00 is the first bar of the session) and how expiry and strike are stored. The file schema lists both column layouts used in the archive.

Step 3: pick the pack that matches your date range

Packs are fixed date ranges you download and keep, not a subscription:

Single years for 1-minute options: 2023, 2024, 2025 and 2026 so far. One year is enough to test an idea across many weekly expiries.

Multi-year: NIFTY options, 3 years, or NIFTY Complete, 1 year and 3 years with futures and spot included.

1-second: all NIFTY 1-second packs are on one page. Each pack page lists its exact first and last dates.

Step 4: pay, then download and open the files

Checkout is by UPI: place the order, pay the amount shown, submit the UTR, and the download link appears on your order page once the payment is confirmed. Download each file as Parquet or CSV.

Files are named by instrument, segment, timeframe, trading day and expiry, e.g. NIFTY_OPT_1min_2026-09-10_exp2026-09-15.parquet, so a day with several listed expiries has one file per expiry. The snippet below loads one file, maps older column names to the sample names and writes a CSV for spreadsheet tools.

import pandas as pd
df = pd.read_parquet("NIFTY_OPT_1min_2026-09-10_exp2026-09-15.parquet")
# older files use layout B names; map them to the sample names
df = df.rename(columns={"timestamp": "datetime", "strike": "strike_price",
                        "option_type": "right", "expiry": "expiry_date",
                        "oi": "open_interest"})
if "right" in df:
    df["right"] = df["right"].replace({"CE": "Call", "PE": "Put"})
print(df.head())
df.to_csv("NIFTY_OPT_1min_2026-09-10_exp2026-09-15.csv", index=False)
