BBG Local Gateway Chrome Extension

Project information

Chrome extension bridging web pages to Bloomberg Terminal data via Chrome's native messaging API. A PowerShell native host loads the Bloomberg .NET SDK and keeps a live session open for the entire browser session. Web pages on localhost/LAN call chrome.runtime.sendMessage to request BDP, BDS, BDH, intraday bars/ticks, field search, and security lookups. No HTTP server, no cold starts — the Bloomberg session is always warm. An install.ps1 script handles registry setup for Chrome and Edge. Requires bbcomm running and a logged-in Bloomberg Terminal.
