Questions

What does it cost?
Your first month of ORTEX Advanced is $7.99. After that it is $149 a month, billed monthly, until you cancel. Prices are shown in your local currency where available.
Can I cancel?
Yes, cancel anytime. Advanced is a monthly plan with no annual commitment; manage or cancel it in the app whenever you like.
Is the short interest really live?
Exchanges publish short interest twice a month, about a week late. ORTEX estimates it from securities-lending data instead: a daily estimate for 52,700+ securities, re-estimated through the trading day for 16,900 US securities, with cost to borrow, utilization, availability and days to cover beside it. Figures are ORTEX estimates and revise as new lending data arrives.
Do I get API access?
Yes. ORTEX Advanced includes API access for your own scripts and spreadsheets. If you need more calls or whole-universe bulk endpoints, the API Trader, Quant and Developer tiers are sold on their own, and every account comes with a TEST key to integrate against before you subscribe.
Which stocks and markets are covered?
Prices and reference data for 125,000+ listings, daily short interest for 52,700+ securities (re-estimated intraday for 16,900 US names), options on 5,900 US underlyings, insider transactions from more than 50 markets and Stock Scores for 47,100 companies. Advanced includes every dataset on the platform.
Can I look around before I pay?
Yes. Create an account with no card and you get the stock pages, the news feed, watchlists and the TEST API key. The first-month offer unlocks everything on this page.

Short interest, cost to borrow, availability and utilization are ORTEX estimates produced by our models, not exchange or regulatory filings, and revise as new lending data arrives. Rule-based screens and backtests are defined conditions over ORTEX data with hypothetical historical statistics, gross of costs. Example tables are illustrative, not live values. ORTEX data is provided for information only and is not investment advice or a recommendation to buy or sell any security. Past performance is not a reliable indicator of future results.
