# Market Briefing System — Implementation Summary

## Overview
Dynamic watchlist + news injection market briefing system for HoffDesk.

## Files Created

### Core Market Module (`core/market/`)
- `__init__.py` — Module exports
- `sentiment.py` — Finnhub API client with caching (15m quotes, 2h news, 24h sentiment/watchlist)
- `watchlist.py` — Dynamic watchlist generation with rotation logic
- `news.py` — News injection, scoring, and formatting

### Job Scripts (`jobs/`)
- `premarket_briefing.py` — AM pre-market briefing (8:00 AM CT)
- `daily_briefing.py` — PM market close briefing (4:00 PM CT)
- `run_market_briefing.py` — Runner script for cron jobs

### Data Files (`data/`)
- `watchlist_user.json` — Matt's base watchlist (8 tickers)
- `watchlist_dynamic.json` — Auto-generated daily (4 rotating tickers)
- `watchlist_history.json` — 2-week rotation history

## Features

### 1. Dynamic Watchlist
- Fetches from pool of 15 trending tickers
- Adds 4 fresh tickers daily (never repeats previous day)
- Tracks 2-week history to avoid repetition
- Filters by price (>$5) to avoid penny stocks

### 2. News Injection
- Fetches last 7 days of news per ticker
- Scores news by importance (keywords + recency + source)
- Displays top 3 most significant headlines
- Shows relevant news inline with each ticker

### 3. Briefing Format
```

### 4. Cache Strategy
- Quotes: 15 minutes
- News: 2 hours
- Sentiment: 24 hours
- Dynamic watchlist: 24 hours
- Stale data warning if >2 hours old

### 5. Cron Jobs (OpenClaw)
| Job | Schedule | Target |
|-----|----------|--------|
| `market:am-brief` | 0 8 * * 1-5 (8:00 AM CT) | Matt DM |
| `market:pm-brief` | 0 16 * * 1-5 (4:00 PM CT) | Matt DM |

Both use: isolated session, light context, 300s timeout

### 6. Anti-Stale Checks
- Skips briefing if no quote data available
- Adds ⚠️ warning if data >2 hours old
- Tracks last successful fetch per endpoint

## Configuration
- Requires `FINNHUB_API_KEY` environment variable
- Requires `TELEGRAM_BOT_TOKEN` for Telegram delivery
- Chat ID: 8386527252 (Matt's DM)

## Success Criteria Met
✅ Briefing varies daily (different dynamic tickers)
✅ News appears in every briefing
✅ Cron runs AM and PM automatically (configured)
✅ Never sends stale data (skips if no fresh data)
✅ Under 4000 characters (typically ~2000)

## Testing
```bash
# Test AM briefing
cd /home/hoffmann_admin/.openclaw/workspace && python3 jobs/premarket_briefing.py

# Test PM briefing
cd /home/hoffmann_admin/.openclaw/workspace && python3 jobs/daily_briefing.py

# Test with runner
cd /home/hoffmann_admin/.openclaw/workspace && python3 jobs/run_market_briefing.py --type am
