📈 Scan biotech news for catalyst trades with FinBERT, Alpaca, and Gemini
⚡ 78 views · 📈 Crypto Trading & Stock Market
Description
Automatically scan major financial newswires for biotech catalyst events, score them with AI sentiment analysis, and surface ranked trade candidates — all without manual monitoring.
Who’s it for
Traders and quant hobbyists who follow biotech stocks and want an automated pipeline to flag high-probability catalyst events (FDA approvals, Phase 3 readouts, M&A) before the market fully reacts.
How it works
The workflow runs four layers on a scheduled loop. Layer 0 polls PRNewswire, GlobeNewswire, and BusinessWire every minute and stores new articles in a data table. Layer 1 filters for biotech keywords, classifies the event type, and runs FinBERT sentiment analysis via HuggingFace — only PROCEED events advance. Layer 2 pulls real-time quotes and 20-day volume bars from Alpaca to calculate spread percentage and relative volume. Layer 3 sends qualifying candidates through a Gemini LLM prompt for final trade scoring and stores results.

- Open the
Alpaca - latest barsnode and paste your Alpaca API key and secret - Create five data tables:
