About

StreamXLS is a Windows RTD server that streams live data from Interactive Brokers into Microsoft Excel. It connects to Trader Workstation or IB Gateway through the TWS API and delivers account, position, order, and market data into worksheet cells via Excel-native RTD formulas - no add-in, no VBA, no programming. Users can build their own Excel dashboards, watchlists, and portfolio trackers in any layout, with values that update in realtime. StreamXLS covers stocks, futures, options (including greeks) and FX; supports multiple accounts (including Financial Advisor structures). Requires desktop Excel on Windows, an Interactive Brokers account, and the user's own market data subscriptions. 30-day free trial.
