Frequently Asked Questions
What is BhavCopyData Insights?
BhavCopyData Insights is a free market-intelligence website built on end-of-day NSE bhavcopy data. It turns the exchange's raw daily CSV files for ETFs, corporate bonds, SME securities, futures, options, and block & bulk deals into searchable tables with computed signals — daily change, 52-week positioning, liquidity tiers, circuit hits, open-interest build-up, and turnover rankings.
What is NSE bhavcopy data?
A bhavcopy is the official end-of-day price report the National Stock Exchange publishes after every trading session. It lists open, high, low, close, previous close, traded quantity, number of trades, and turnover for each security. NSE distributes separate bhavcopy files per segment (equities, SME, debt, F&O), and this site ingests and enriches them each evening.
Is BhavCopyData Insights free to use?
Yes. Every page and every CSV download is free. There is no login, paywall, or usage cap for normal browsing.
How often is the data updated?
Automatically after each trading day's close. An automated pipeline downloads the day's NSE files in the evening (roughly 7:30–8:30 PM IST), recomputes insights, and refreshes every page. Delivery-percentage data lags by one trading day because NSE publishes that file close to midnight IST.
Which markets and instruments are covered?
NSE (India) only: exchange-traded funds, corporate bonds (both the equities-segment bond bhavcopy and the CBM Trade Report yields), SME stocks, single-stock and index futures and options, and block & bulk deal disclosures.
Can I download the underlying data?
Yes. Every instrument page has ‘Raw CSV’ and ‘Insights CSV’ buttons on its Data tab, and the same files are linked from each page's structured data. Bulk scraping or redistribution is not permitted — see the Terms of Use.
Does the site provide investment advice?
No. Everything here is end-of-day data and derived statistics for research and informational use only. Nothing on the site is investment, trading, tax, or legal advice. Verify prices, filings, and corporate actions independently before acting.
Where does the data come from?
Publicly available NSE bhavcopy and related exchange files. The site reorganizes and annotates that data; it does not originate quotes or filings.
How much history is available?
It varies by instrument. ETF, corporate bond, SME, and block/bulk deal history goes back further; the CBM Trade Report yields start from August 2026; F&O carries about nine months of backfilled history. History depth grows over time as the daily pipeline runs.
How do I report an error?
