Data Sources
Last updated May 16, 2026
What This Page Covers
TickerPosts is a community discussion site. The numbers and lists you see on the site are not produced by TickerPosts directly. We pull them from public datasets and present them alongside community discussion. This page explains where each piece of data comes from, how often it refreshes, and what its known limits are, so you can judge for yourself how much to rely on it.
Ticker Listings
The list of tickers searchable on TickerPosts (NASDAQ, NYSE, and AMEX) comes from the public US-Stock-Symbols dataset on GitHub. It is updated by its maintainers on a regular basis and includes the symbol, the company name, the listing exchange, and basic classification fields such as sector and industry where available.
Listings can change between ingest runs (new IPOs, delistings, ticker changes, mergers, splits). If a ticker you expect is missing or out of date, the canonical source of truth is the exchange itself or the company's SEC filings, not TickerPosts.
Price And Market Data
Daily price snapshots (last sale, net change, percent change, volume, market cap) and historical price series come from the same public US-Stock-Symbols dataset linked above. The site stores a rolling daily history per ticker so the chart on each ticker page can render without a live feed.
Prices on TickerPosts are end-of-day snapshots, not a real-time quote. They can be delayed, incomplete, or affected by data-source outages. Do not use TickerPosts as your only source for time-sensitive trading decisions. Confirm any number that matters with your broker, your data terminal, or the exchange.
Charts
Charts on ticker pages are rendered in your browser from the daily price history we already store. We use the open-source Lightweight Charts library from TradingView for the drawing layer. The library only handles rendering. It does not pull live quotes and does not transmit your activity back to TradingView.
Community Content
Comments, replies, reports, and watchlists are produced by community members and stored by TickerPosts. They are the personal opinions of the people who wrote them. They are not edited by TickerPosts before they appear, and they are not investment advice. Read the disclaimer and the community guidelines for how user content is moderated and what is not allowed.
Why We Publish This
Stock-discussion sites are an easy place for bad numbers to spread. Listing our data sources in plain English is one of the simplest trust signals we can give: if you want to check a price against the original source, you know where to look. If a source ever changes (for example, if we switch to a different provider for daily prices), this page will be updated to match, with a note in the changelog.
What TickerPosts Does Not Provide
TickerPosts does not provide real-time tick data, level-2 order-book data, options chains, intraday news feeds, analyst price targets, insider-transaction filings, or institutional ownership records. Many of those are available from regulator websites and broker terminals. For SEC filings specifically, search the company on EDGAR.
Reporting A Data Issue
If you spot a price, market cap, sector tag, or company name that looks wrong on a ticker page, please leave a comment on that ticker so the moderation team can take a look. We treat data accuracy as part of moderation, not as a separate ticket queue. For posts that look like coordinated promotion or other manipulation, use the report control on the post itself. For anything else, email tickerposts@fastmail.com.
Changes To This Page
If a data source changes, or if we add a new category of data (for example, earnings dates, dividend history, or SEC filing summaries), this page will be updated and the change will be noted in the changelog.
