The SignalR Bridge (quanux-bridge-signalr) is a specialized extension that maintains persistent WebSocket connections to TopstepX's SignalR Hubs. It bridges the gap between the proprietary SignalR protocol and QuanuX's internal messaging.
extensions/python/signalr_bridgeextensions/python/signalr_bridge/extension.yamlextensions/python/signalr_bridge/src/node (Preferred)extensions/python/signalr_bridge/src/flask (Legacy/Fallback)The bridge runs as a standalone process (supervised by QuanuX).
rtc.topstepx.com (User/Market Hubs).This bridge is pre-configured for TopstepX logic but is technically generic.
Key Environment Variables (Managed via quanuxctl topstepx env):
QUANUX_SIGNALR_USER_HUB: URL for the User Hub (Login, Orders, Fills).
https://rtc.topstepx.com/hubs/userQUANUX_SIGNALR_MARKET_HUB: URL for the Market Hub (Quotes, Level 2).
https://rtc.topstepx.com/hubs/marketThe bridge is usually started automatically by quanuxctl bridge or the main server.
To verify functionality manually:
# In extensions/python/signalr_bridge
python src/supervisor.py
The Node runtime exposes a health endpoint:
curl http://localhost:8077/health
Response should include "status": "ok" and "hubUrl".
QUANUX_SIGNALR_USER_HUB is set correctly.SIGNALR_ACCESS_TOKEN which is usually refreshed and injected by the main quanux-topstepx auth flow. If authentication fails, the bridge cannot connect.~/.quanux/logs/quanux-bridge-signalr.log.src/node/index.mjs. Uses @microsoft/signalr client.
