Where Flash Finance data comes from
Every number on Flash Finance traces back to a public exchange publication or a company filing. This page lists each dataset, where it comes from, when it refreshes, the pages that use it, and its known limits.
| Dataset | Source | Refresh | Used on |
|---|---|---|---|
| Share prices (end of day)The 11:00 run is a partial-day candle. Technical scores ignore the current day until after 16:30 IST so they never score a half-finished session. | NSE and BSE daily prices, collected through Yahoo Finance's market-data feed | Around 11:00 IST (intraday snapshot) and 17:00 IST (close), trading days | Stock pages, Technical screener, Valuation ratios |
| Index levels and valuations | NSE index archive files and BSE index archive (P/E, P/B, dividend yield, OHLC) | 11:00 and 17:00 IST; history back to 2019 | Index valuations, Sector rotation, Market today |
| Quarterly and annual resultsExtraction uses AI with two publish gates (period cross-check and history sanity check). Every figure links back to its quarterly table. | Financial results filed by listed companies with NSE and BSE; some older periods back-filled from third-party financial data | New filings are extracted every 15 minutes during results season | Fundamentals, Fundamental screens, Comparisons |

Using Flash Finance data
You are welcome to quote and cite figures from Flash Finance, such as the market health score, breadth readings, screen results or methodology, with a link to the page you took them from. Please do not republish whole tables or scrape the site in bulk. The underlying exchange data remains the property of NSE and BSE and is subject to their terms; derived figures (scores, rankings, z-scores, backtests) are Flash Finance's own work. Everything is provided as information only, without warranty, and is not investment advice. Free embeddable widgets are available if you want live figures on your own site.
How freshness is shown
Every data page carries a "data as of" date for the session it describes. When one feed lands later than another (NSE publishes different files at different times each evening), the page shows the older session for that section and says so, rather than mixing two days into one table. If a feed fails, the previous session's data stays up with its date shown, instead of an empty page.
Times are Indian Standard Time. Evening builds run at 18:05, 18:20, 21:15 and 21:40 IST on trading days; the second run of each pair repairs anything the first missed.
