About — who runs this and where the data comes from

Options Data (optionsdata.shop) is an independent data vendor. The archive is built from exchange-traded prices collected from a broker data feed, cleaned and canonically named, and sold as fixed-price packs of files you download and keep.

Who runs it

Options Data is a small independent business in India. Much of the day-to-day work — the data pipeline, the site and first replies — is automated; every payment is checked and approved by hand. There is no sales team. Support is by email at myawshome259@gmail.com, usually answered the same day (8 AM – 11 PM IST).

If you are about to spend a meaningful amount, message before you pay. Ask for the exact date range you need; the answer is a screenshot of the live catalog rather than a promise.

Where the data comes from

Everything in this archive is exchange-traded prices collected from a broker data feed — a retail broker's historical data API, not an exchange licence. It is stated plainly because you should know what you are buying and because the source determines the limits.

Independent data vendor. Not affiliated with NSE/BSE/MCX. We are not an exchange-authorised data vendor. Authorised vendors buy their feed from the exchange under licence, and for real-time trading that authorisation matters. This is a research archive assembled from a broker API, and it inherits that API's coverage and its holes.

What the source determines: 1-minute NSE derivatives history begins in 2021 and cannot go deeper, BSE derivatives begin later still, and second-level history is served on a rolling window of about three years. No amount of effort on our side changes any of those floors, which is why the coverage table is published rather than summarised.

How it is cleaned

Raw feed output is not usable as-is. Every file in the archive has been through the same pipeline: expiry probing to find which contracts actually existed on each day, de-duplication of overlapping fetch windows, removal of phantom contracts the API reports but never traded, canonical file naming so a filename tells you the instrument, segment, timeframe and date, and a consistent column schema across every instrument.

That work is most of the value at 1-minute resolution, where a determined developer could rebuild the raw data themselves in a weekend. At 1-second resolution the acquisition itself is the value — the rate limits make a full rebuild a multi-year job.

What we do not have

No bid/ask quotes or order-book depth. No Greeks. Many option files include an iv column taken as-is from the data feed; we do not compute or verify it. No true tick-by-tick — our finest resolution is a 1-second bar, and we will not call it tick data. No equity or stock F&O coverage; this is index derivatives and MCX commodities. No real-time feed of any kind.

If you need any of those, exchange-authorised data vendors sell them.

How to check us before paying

Three things, all free. Read the live coverage page, which is generated from the catalog rather than written by hand and shows exactly what is held. Read the file schema — every column, every type, no signup. Then ask for a sample of the exact series you are considering, and message us with your date range before you order.

A vendor who publishes what they do not have is making a bet that honesty converts better than a sales page. That is the bet this whole site is built on.
