Sources
Every number on this site comes from one of these sources and shows which one, with its "as of" time. No website is scraped, and nothing is read from a TradingView widget. How the numbers are built: methodology.
- Databento US Equities Mini · US-listed prices (NYSE, Nasdaq, NYSE American) and the price history behind the company-page charts. A last sale across several venues, not the official closing auction. Updates every minute while US exchanges are open (delayed prices every 5 minutes when the live feed is interrupted); the session’s last sale loads overnight.Credit: Prices: Databento US Equities Mini
- SEC EDGAR · Share counts, filings, insider transactions, IPO and lock-up terms. Updates new filings every 10 minutes, each company’s filing list hourly, share counts daily.Credit: Source: SEC EDGAR
- Bank of Canada · The US dollar to Canadian dollar exchange rate behind the CAD toggle. The rates are free on the Bank’s website. Updates daily, with the overnight update.Credit: Source: Bank of Canada
- TradingView widgets · Quotes for listings outside US exchanges, on company pages only. The widget shows its own figures; this site never reads, stores or ranks them, and never puts a widget behind a paywall. Updates by TradingView, inside the widget.Credit: The widget’s own TradingView links are kept
- The Space Devs, Launch Library 2 · Launch schedule, tied to the listed company that provides the launch and, where known, the one that owns the payload. Updates hourly.Credit: Launch data: The Space Devs (Launch Library 2)
- USAspending · Federal contract awards, matched to companies by recipient UEI. Defense awards appear there about 90 days after signing. Updates daily.Credit: Source: USAspending.gov
- Logo.dev · Company logos, downloaded once and served from this site, so readers’ browsers never contact Logo.dev. Logos remain their owners’ trademarks and imply no endorsement. Updates when a company is added, checked again every 90 days.Credit: Logos provided by Logo.dev
- beehiiv · Sends SpaceValued Weekly and hosts its sign-up form. One email a week.
