Identify the true supply of tradable shares with ORTEX’s Free Float API. Perfect for uncovering liquidity constraints, gauging volatility potential, or analyzing a stock’s short interest environment, the Free Float API helps you pinpoint exactly how many shares are available to the public. With consistent and timely updates, it’s an invaluable resource for quant modeling, risk assessment, or portfolio optimization. Integrate ORTEX’s Free Float data directly into your platform to unlock more precise market perspectives and gain a definitive edge.

Available Data Points:

• Date: Starting date of free float numbers.
• Free Float Shares: Number of free float shares.
• Free Float Percent Of Outstanding: Percentage of free float shares from the total outstanding shares.

Resolving renamed, delisted or moved tickers (US only)

ticker_as_of_date (yyyy-mm-dd) selects which instrument the ticker refers to, as of that date. It changes instrument resolution only — it does not filter the returned data (the date range is still from_date / to_date). Tickers get reused, renamed and delisted, so by default a ticker that is no longer active returns 404 and a recycled ticker resolves to today's owner. With this set, the URL path exchange is ignored and all US exchanges are searched for whoever held the ticker on that date, letting you pull history for a company that has since changed ticker, delisted, or moved exchange. Omit it for the current, unchanged behaviour; a non-US instrument with this parameter returns 400.
