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
