Data Sources

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 If a ticker you expect is missing or out of date, the canonical source of truth is the exchange itself or the company's SEC filings, not TickerPosts.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.

How Trending, Movers, And Most Discussed Are Ranked

The ranked lists on the homepage are computed from the data described above, with no editorial hand-picking. Each one is a plain calculation:

• Top Gainers and Top Losers rank tickers by their daily percent change, largest move first, from the most recent end-of-day snapshot.
• Highest Volume ranks tickers by the number of shares traded in the most recent snapshot, highest first.
• Most Discussed ranks tickers by how many comments their discussion received in a recent window, most active first. It measures conversation volume, not sentiment, and a high spot is not an endorsement.
• Trending surfaces tickers with the most recent discussion activity so you can see what the community is talking about right now.

None of these lists is a buy or sell signal. A stock can top a list because of good news, bad news, a scheduled event, or a coordinated promotion. The lists are a starting point for a closer look, not a recommendation. TickerPosts does not currently publish a computed bullish-or-bearish sentiment score; where the word sentiment is used on the site it refers to what people are saying in the discussion, not a number the site generates.

When Data Is Delayed Or Missing

Because prices are end-of-day snapshots rather than a live feed, there is always some lag between the market and what you see here, and a snapshot can be late or skipped if the underlying data source has an outage. When a ticker has no recent snapshot, the page shows the last figure it has rather than inventing one, and the chart simply stops at the last day with data. A missing or stale number is a data gap, not a statement about the company. For anything time-sensitive, confirm against your broker or the exchange.

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 [email protected].

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.
