# live-feed

This skill writes a script that subscribes to OpenAlgo WebSocket feeds and computes indicators on the live stream. Useful when you need a real feed instead of a backtest.

## What it does

The skill creates `{symbol}_live_feed.py` under `charts/live/`, starting from the template in its rules. Data arrives over the OpenAlgo WebSocket: an LTP, Quote or Depth subscription, a rolling tick buffer, EMA and RSI computed on it. A `multi` mode keeps a watchlist table with auto-refresh.

You need `OPENALGO_API_KEY` and a host in your environment before running anything, and the script pulls history through `client.history` to seed the buffer. No key means no subscription, so check `.env` first. Ctrl+C is handled: the script unsubscribes from every feed and closes the socket.

The `verbose` level decides what gets printed, from errors only to every data update. Arguments come in as `[symbol] [exchange] [mode]`; with none given, the skill asks for the symbol and the feed type.

## When to use it
- stream quotes over WebSocket and compute indicators on each tick
- build an L5 order book view with spread and order imbalance
- show a watchlist table across several symbols at once
- seed the indicator buffer from historical candles
- unsubscribe and disconnect cleanly on Ctrl+C

## Example prompts
- /live-feed SBIN NSE ltp
- /live-feed NIFTY NSE_INDEX quote
- /live-feed SBIN NSE depth
