Data is scraped daily from the [FI public registry](https://marknadssok.fi.se/Publiceringsklient) and auto-deployed via Cloudflare Pages. No backend — all analysis runs client-side.

## Features

- **Signal Grading** — acquisitions ranked Table-Pounding / Conviction / Watch / Token by SEK value

- **Cluster Detection** — flags stocks where 2+ insiders buy within 30 days

- **CEO + CFO Alerts** — when both C-suite officers buy within 90 days

- **Market Segments** — Large / Mid / Small Cap via ISIN lookup with Yahoo Finance market caps

- **Backtested Tags** — Large Cap CFO buys (79.8% win rate), Huge Single (≥10M SEK), Chairman Warning (inverse signal)

- **CSV Export** — download any filtered view

## Architecture

```

fi-insider/

├── scraper/       # Node.js scraper → outputs to frontend/public/data/

├── frontend/      # React + Vite + Tailwind CSS dashboard

└── .github/       # GitHub Actions for automated daily scraping

```

**Data flow:** Scraper fetches HTML from `marknadssok.fi.se`, parses with cheerio, writes per-year JSON files. GitHub Actions runs daily at 15:45 UTC. Cloudflare Pages auto-deploys on every commit.

## Local Development

```bash

# Scraper

cd scraper && npm install && npm start

# Frontend

cd frontend && yarn install && yarn dev

# → http://localhost:6175

```

## Tests

```bash

cd frontend

yarn test             # run once

yarn test:coverage    # with coverage report
