Daily bars, quotes, reference data, headlines, and short interest come from Massive, formerly Polygon, a licensed market data vendor. The age of the quotes is shown at the top of every page. Insider trades, notable holders, and profits come straight from the SEC. That means Form 4 filings, 13F filings, and XBRL financial data on EDGAR. Where a company's SEC figures leave the Quality Score's sales, share count, or cash flow line empty, the score reads that figure from Massive's statements, and the Score tab says so. Government filings come from the public STOCK Act and Office of Government Ethics disclosures. The market-wide headlines on the market line also come from the public headline feeds CNBC, MarketWatch, and Yahoo Finance publish, shown as the headline, the source, and a link to the article. Splits, dividends, and the financial statements on each ticker page come from the vendor's reference data. The 8-K filings on EDGAR are read for the items that move a price. Five years of history is loaded for every stock. So the 200-day and 52-week checks rest on real history. Options flow is not part of the product.
