Angel SmartAPI Market Feed

I already hold an active SmartAPI key from Angel Broking and now need a developer to wire it into my analytics stack. The goal is simple: stream real-time stock prices, trading volume, and market indices into a format I can query or visualize at will.

What I expect from you is a lightweight service—Python preferred because the rest of my tooling is in pandas and Plotly, but Node.js is fine if that speeds you up—that authenticates, subscribes to the relevant WebSocket channels, and keeps the connection alive with solid reconnect logic so no ticks are missed. Push the incoming data either to a small REST endpoint or directly into a Postgres table; choose whichever you can deliver most reliably.

Deliverables
• A runnable script or micro-service that continuously fetches the live feed
• Step-by-step setup notes covering token generation, environment variables, and Ubuntu deployment
• One sample output file or database snapshot illustrating the captured fields

I’ll sign off once the service runs on my VPS for 30 minutes without a parsing error or gap in the stream and your README leaves me confident to maintain it myself.
