1.1 Workflow description

Title: Scan biotech news for catalyst trades with FinBERT, Alpaca, and Gemini
Workflow name: Scan biotech news for catalyst trades with FinBERT, Alpaca, and Gemini

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.

How to set up

Add your HuggingFace API credential in n8n
Add your Google Gemini API credential in n8n
Open the Alpaca - latest bars node and paste your Alpaca API key and secret
Create five data tables: news_events, processed_events, trade_candidates, llm_analysis, market_snapshots
Activate each schedule trigger

Requirements

n8n with Data Tables enabled (self-hosted or cloud)
HuggingFace account (free tier)
Alpaca Markets account (free tier)
Google Gemini API key

How to customize

Swap the GlobeNewswire RSS feed URL to target a different sector. Adjust the biotech keyword list in the Biotech Keyword Filter node. Tune the spread % and relative volume thresholds in Eligibility Check to tighten or loosen your trade criteria.

Send portfolio risk reports with Google Sheets, GPT-4o-mini and Gmail

## Quick Overview This workflow receives a portfolio via webhook (uploaded CSV or Google Sheets), calculates allocation and concentration risk metrics, generates an OpenAI HTML risk report, emails it through Gmail, and returns a JSON API response with the report status. ## How it works 1. Receives a POST webhook request containing a portfolio source type plus user name and email. 2. Loads holdings either by decoding an uploaded base64 CSV into rows or by reading rows from Google Sheets. 3. Combines all holdings into a single dataset and attaches user and source metadata. 4. Calculates portfolio totals, position weights, sector and asset-class breakdowns, concentration flags, top gainers/losers, and an overall risk score and label. 5. If the portfolio is valid, sends the computed metrics to OpenAI to generate a client-ready HTML risk narrative. 6. Builds a formatted HTML email that includes the AI analysis plus sector and top-holdings tables, then sends it to the user via Gmail and returns a success JSON response. 7. If the portfolio is empty or invalid, emails a failure notice via Gmail (when an email is provided) and returns a 422 JSON error response. ## Setup 1. Create and connect credentials for Google Sheets OAuth2, OpenAI, and Gmail OAuth2. 2. Configure the webhook endpoint by copying the production URL and sending POST requests to the /portfolio-analyze path. 3. For CSV submissions, include base64 CSV content in body.fileData (or body.csvBase64/body.file) and ensure the columns include ticker, company, sector, quantity, avg_buy_price, current_price, and asset_class. 4. For Google Sheets submissions, update the spreadsheet document ID and sheet (gid) to the holdings table you want to analyze. 5. Ensure the request includes userEmail (body, query, or x-user-email header) so the workflow can deliver the report or validation error message.

Analyze commodity portfolio diversification with Sheets, Gemini, and Gmail

## Quick Overview This workflow reads a gold/silver/oil portfolio from Google Sheets, pulls current commodity prices and a recent gold trend from GoldAPI, EIA, and Twelve Data, calculates allocation and HHI concentration risk, generates a Gemini analysis, and emails an HTML diversification report via Gmail. ## How it works 1. Starts manually and loads configuration values, then reads your portfolio holdings from Google Sheets. 2. Fetches real-time gold and silver prices in INR from GoldAPI, retrieves crude oil prices in USD from the EIA API, and converts oil prices to INR. 3. Pulls the last two daily closes for GLD from Twelve Data and compares them to label the gold market trend as UP or DOWN. 4. Aggregates the latest commodity prices and trend data, then calculates portfolio allocation percentages and an HHI concentration score from the Google Sheets holdings. 5. Sends the allocation, HHI score, and gold trend to Google Gemini to generate a structured risk assessment, rebalancing recommendations, trend impact, and a verdict. 6. Parses Gemini’s response into dedicated fields, builds a formatted HTML report with prices, allocations, risks, recommendations, and verdict, and sends it to the configured recipient via Gmail. ## Setup 1. Add API keys for GoldAPI, the U.S. EIA API, and Twelve Data in the configuration step (and confirm the USD-to-INR conversion rate is correct for your needs). 2. Connect your Google Sheets account, then update the spreadsheet and sheet tab to a portfolio table that includes commodity_name and buy_price for gold, silver, and oil. 3. Connect your Google Gemini (PaLM) API credential and ensure the selected model is available in your account. 4. Connect your Gmail OAuth2 credential and set the recipient email address used for the report delivery.

Log gold and silver prices and email Groq insights with Google Sheets

## Quick Overview This workflow manually logs daily Gold and Silver prices from GoldAPI into Google Sheets, summarizes historical monthly averages, generates seasonal insights with Groq (LLM), builds QuickChart bar charts, and emails a formatted report via Gmail. ## How it works 1. Starts manually and loads a two-item asset list (Gold/XAU and Silver/XAG) to process in a loop. 2. For each commodity, calls the GoldAPI endpoint to fetch the latest INR price and converts it into a per-10g value with date and month fields. 3. Checks Google Sheets for an existing row for the same commodity and date, keeps the higher of the two prices, and appends or updates the row in the historical sheet. 4. Reads the full historical dataset from Google Sheets and calculates monthly average, minimum, and maximum prices grouped by month and commodity. 5. Formats the monthly averages into a text block and sends it to a Groq-hosted chat model to generate a structured JSON insight summary for gold, silver, and the overall trend. 6. Creates QuickChart URLs for separate Gold and Silver monthly-average bar charts and emails the AI summary and chart images using Gmail. ## Setup 1. Add a GoldAPI key and set it in the HTTP request header (x-access-token) for the GoldAPI call. 2. Connect Google Sheets OAuth credentials and select the target spreadsheet and sheet tab where rows are stored (e.g., the 04_HistoricalData sheet). 3. Ensure the sheet has columns for ID, Date, Month, Price, and Commodity, and that ID is used as the upsert/matching key. 4. Add Groq API credentials for the Groq chat model used to generate the JSON insights. 5. Connect Gmail OAuth credentials and replace the placeholder recipient address ("RECEIVER MAIL ID") and subject as needed.
