Where the data comes from

Every figure on EquityWise starts at an exchange or a company filing. This page lists the sources and how often each is refreshed.

Last updated: October 2026

Prices

  • End-of-day prices for the screener and stock pages come from the National Stock Exchange of India’s (NSE) published end-of-day files, read after each session closes. They cover NSE mainboard stocks in the EQ, BE and BZ series.
  • Prices during market hours (watchlists, the portfolio) and price history are read from the market-data services of Indian stockbrokers. EquityWise only reads prices from them; it never connects to anyone’s trading account.

Filings, flows and corporate actions

  • Company announcements: the implementation can read BSE corporate filings and match them to NSE symbols by ISIN, but new BSE ingestion is disabled unless a written data agreement has been approved.
  • Delivery, bulk and block deals, and F&O open interest come from NSE’s daily archive files, published after each close.
  • FII and DII cash activity and promoter and public shareholding come from NSE’s public data.
  • Splits, bonuses and dividends come from NSE’s corporate-action records. Splits and bonuses are applied to price history as described on the methodology page; dividends are never applied to prices.
  • Large, mid and small-cap labels: the implementation can read AMFI’s half-yearly list, but refresh is disabled unless written reuse permission has been approved. Any older stored label must be read with its period date.

IPOs

IPO dates, price bands, lot sizes, issue sizes, registrars, lead managers, offer documents and subscription figures come from NSE’s public IPO pages and are shown with the time each was read. Listing-day prices come from NSE’s end-of-day file. Dates marked “expected” are calculated from SEBI’s T+3 timetable until the exchange publishes them.

Sections shown “from the offer document” are read automatically from the Red Herring Prospectus the exchange publishes and quoted as the company wrote them, with the page they came from; check the document itself. Draft offer documents (DRHPs) are listed as filed with SEBI, linked to SEBI’s page; a filing is not an announced issue.

The grey-market premium (GMP) is an unofficial, unregulated quote that no exchange or regulator publishes. EquityWise is not currently ingesting or displaying third-party GMP values while written reuse permission is unresolved. GMP is not a forecast of the listing price.

How fresh it is

  • After each close: the end-of-day pass runs after 15:30 IST once the exchange has published its files, and recalculates every indicator and screener measure. Stock pages say which close they show.
  • During market hours (09:15–15:30 IST on trading days): watchlist prices refresh every few seconds to a few minutes, and watchlists show when a price was last updated or if it is stale.
  • Each daily run records which stocks it covered and which failed, so an incomplete day is retried rather than shown as complete.
