Why StockaSearch exists
Financial websites often present large numbers of metrics without explaining what they mean. StockaSearch pairs a focused research interface with plain-language education and separately labeled original analysis. Editorial verdicts are conditional research classifications, not personalized buy or sell instructions, and no metric is presented as a promise of future returns.
The watchlist is a browser convenience rather than an investment recommendation. Users decide which symbols to save, and the list remains on their own browser through a cookie and local-storage backup.
Current quote data
The deployed application first requests quote data through a server-side market-data provider. API credentials remain on the server and are not included in browser JavaScript. A usable quote must contain a positive numeric closing or latest price; error payloads and zero values are rejected.
During regular U.S. trading hours, successful quotes are cached briefly so visitors can share a recent response without creating a new upstream request for every page load. Outside regular hours, the latest stored closing quote can be reused because ordinary session prices are no longer changing. The interface independently calculates whether the regular market is open using New York time.
Historical charts and selected-range returns
Historical points are requested separately for each symbol and range. Intraday data uses shorter intervals; longer ranges use daily, weekly, or monthly observations to keep charts readable. Each successful series is stored by symbol and range in the server-side cache.
The displayed gain or loss is calculated from the first valid plotted price to the most recent valid plotted price for the selected range. The chart’s vertical scale uses the actual minimum and maximum of that series. Corporate actions, provider adjustments, missing observations, and time-zone conversion can affect historical comparisons.
Data fallback and caching
If the primary quote service fails, is rate-limited, returns an error object, or supplies an unusable price, the deployed Cloudflare Worker retries through Yahoo Finance endpoints and stores the valid response in Cloudflare KV. The local PowerShell/Supabase server uses the Python yfinance package as its final quote and historical-data fallback. Python packages cannot execute inside browser JavaScript or a Cloudflare Worker, so the deployed and local environments use equivalent but technically different fallback paths.
A fallback is intended to keep research pages usable, not to certify a value as exchange-grade real-time data. Provider names and update times should be considered when verifying important figures.
Company background from Wikipedia
Company-profile pages request an introductory extract through the official MediaWiki API. The page clearly identifies Wikipedia as the source, links to the original article and contributor history, states the CC BY-SA license, and notes that the extract may be shortened for display.
Wikipedia is used only as an accessible starting point for understanding what a company does. Regulatory filings, audited financial statements, company investor-relations websites, and independent reporting remain the appropriate sources for investment due diligence.
Quality controls and known limitations
- Zero or non-numeric prices are treated as unavailable rather than displayed as genuine quotes.
- Responses are validated before they are written to the shared cache.
- Charts ignore missing or non-numeric historical points.
- Cached data reduces rate-limit failures but can be older than an exchange feed.
- Regular market status does not automatically account for every exchange holiday or emergency closure.
- News headlines come from external publishers and are linked to their original sources.
If data conflicts with a company filing or exchange publication, use the primary source.
Editorial and advertising separation
Educational explanations and stock analyses are written specifically for StockaSearch. Advertising does not determine coverage, verdicts, chart calculations, or watchlist defaults. Ad code is excluded from company-profile, legal, contact, editorial-policy, and navigation-only pages; pages carrying ads must contain substantial publisher-created content.
