Wall Street Horizon
wallstreethorizon.com
Corporate events data for 11,000+ companies, from earnings dates and dividends to analyst days; individuals get it through Interactive Brokers for $49/mo.
What it is
Wall Street Horizon is a data company that tracks corporate event dates: earnings announcements, dividends, stock splits, mergers, shareholder meetings, investor conferences, analyst days, road shows and special business updates. It covers more than 11,000 companies worldwide, across more than 40 event types in its full product range, and its Global Events Calendar alone tracks about 20. The calendar is refreshed every three hours from 5 AM to 8 PM Eastern.
The main customers are institutions: options and equity traders who need to know when volatility events fall, market makers, quant funds, risk and compliance teams and retail brokerage platforms that show the data to their own clients. Delivery is by JSON file over SFTP, through an API and widget via partner Trading Central, and as a companion to Toronto Stock Exchange reference data. Direct pricing is not published; the site asks you to request information.
For individual traders the practical route is Interactive Brokers. IBKR clients can subscribe from their account for $49 a month as retail users ($149 for institutional users), with a free one-month trial, and then see event calendars and filters inside Trader Workstation or pull the events through the TWS API for their own scripts.
