NIFTY tick data download: what you need and what 1-second bars give you

Options Data (optionsdata.shop) does not sell raw tick-by-tick data for Indian index options. The closest downloadable history it sells is 1-second bars: NIFTY options and index, JAN 2023 → OCT 2026, and SENSEX options, MAY 2024 → OCT 2026. For most research that people want tick data for (entry timing, stop placement, slippage on fast moves) one-second OHLC answers the question with far less data to handle. See the NIFTY 1-second dataset.

Tick data versus 1-second bars

Tick data is every individual trade or quote update. It is large, needs careful cleaning and is often sold under exchange licensing.

1-second bars summarise each second that traded: open, high, low, close and volume. You see the path within a minute, which is what matters for intraday stops and fills.

Indian index options at 1 second: NIFTY and SENSEX

NIFTY: 1-second option bars plus the NIFTY index on the same clock, JAN 2023 → OCT 2026. Option files hold the nearest expiries, strikes around the money. See the NIFTY 1-second dataset.

SENSEX: 1-second option bars for the nearest expiries, MAY 2024 → OCT 2026, with OHLC and volume per strike and side. Open interest is 0 in these files; use the SENSEX 1-minute data when you need OI. See the SENSEX 1-second dataset.

Both are Parquet, one file per trading day per expiry, timestamps in IST. No Greeks.

Working with 1-second files

Option files hold the nearest expiries, strikes around the money; the index file is on the same clock.

import pandas as pd
opt = pd.read_parquet("NIFTY_OPT_1sec_2026-09-10_exp2026-09-15.parquet")
spot = pd.read_parquet("NIFTY_SPOT_1sec_2026-09-10.parquet")
print(opt.head(), spot.head())

Which pack

NIFTY: single years from 2023, or the full 1-second archive. SENSEX: the SENSEX 1-second pack. All are listed on the 1-second packs page.
