Common questions.
What is short interest?+
Shares sold short, usually shown as a percentage of the free float (the shares actually available to trade). High short interest means a crowded bet against the stock, and it is a key ingredient in squeeze setups.
How is ORTEX short interest different from the exchange numbers?+
Exchange short interest is a twice-monthly snapshot (positions as of the 15th and the last business day of the month) published about seven business days later, so the official print is already 11 to 12 days old the day it lands, and close to four weeks old just before the next one arrives. ORTEX models short interest from securities-lending data instead and updates the estimate through the trading day, alongside cost to borrow, availability, utilization and days to cover. Figures are ORTEX estimates and revise as new lending data arrives.
How accurate are ORTEX estimates?+
Every estimate is scored against the official record. Since August 2023, 95% of ORTEX short interest estimates were within one percentage point of free float of the official figure, across 2.1 million official prints in the US, Canada, Australia and Hong Kong. Index rebalance forecasts are scored after every review: 85% of add and delete calls were right the day before the announcement, every scheduled review since 2018 across 46 indices.
How is ORTEX data licensed and delivered?+
Every dataset can be licensed on its own or together, and delivered over the REST API (JSON or CSV), as whole-market daily files over SFTP or S3, through the Python SDK and Excel add-in, or on the ORTEX platform. Every dataset shares one set of identifiers, and trials with history are available on your own universe.
What is the cost to borrow (borrow fee)?+
The annualized fee a short seller pays to borrow shares. A rising borrow fee means the lending market is tightening, which makes shorts more expensive to hold.
Do I need a credit card to try ORTEX?+
No. A free account takes under a minute and needs no card. Upgrade to Basic or Advanced when you want more, and manage or cancel your plan in the app at any time.
Can I get the data into my own tools?+
Yes. Everything ships over a documented REST API and Python SDK, and as a native Excel add-in, so the same numbers reach your models and spreadsheets without re-keying. API plans start with a free TEST key.
Which markets does ORTEX cover?+
Prices and reference data for 125,000+ listings from 1964, daily short interest for 52,700+, insider transactions from more than 50 markets, 17,700+ ETFs and 134 alternative datasets from more than 50 countries. The data catalog lists coverage and history for every dataset.
