§ 02 · Why StreamXLS

Your whole trading dashboard, live in Excel.

If you use Excel and trade with Interactive Brokers, you've built something to bridge them — a copy-paste routine, a DDE link, a VBA script, a Python shim. Each of those solutions comes with drawbacks because Excel wasn't designed to stream live data that way.

StreamXLS is the realtime bridge that supports professional dashboards and production data streams. Market quotes, account values, positions, and orders stream into the grid through one Excel native =RTD() formula — the whole desk can be put on one screen.

And it's built to keep itself up. If the link drops it reconnects and resubscribes, and it keeps receiving updates from TWS even while Excel is busy. With StreamXLS you can stop watching the plumbing and get back to trading.
