--- name: stock-market-pro description: >- Yahoo Finance (yfinance) powered stock analysis skill: quotes, fundamentals, ASCII trends, high-resolution charts (RSI/MACD/BB/VWAP/ATR), plus optional web add-ons (news + browser-first options/flow). ---

Stock Market Pro

Stock Market Pro is a fast, local-first market research toolkit. Get clean price + fundamentals, generate publication-ready charts with indicator panels (RSI/MACD/BB/VWAP/ATR), and run a one-shot report that outputs both a summary and a high-res PNG. Optional add-ons: quick news link sweep (DDG) + browser-first options/flow (Unusual Whales).

What you can do

• Get real-time quotes (price + change)
• Summarize fundamentals (Market Cap, Forward PE, EPS, ROE)
• Print ASCII trends (terminal-friendly)
• Generate high-resolution PNG charts with overlays/panels:

- RSI / MACD / Bollinger Bands / VWAP / ATR

• Run a one-shot report that prints a compact summary and emits a chart path
• Search news links via DuckDuckGo (ddgs)
• Open options / flow pages (browser-first, Unusual Whales)

Web Add-ons (Optional)

A) News search (DuckDuckGo via ddgs)

This skill vendors a helper script (scripts/ddg_search.py).

Dependency:

pip3 install -U ddgs

Run:

python3 scripts/news.py NVDA --max 8
# or
python3 scripts/ddg_search.py "NVDA earnings guidance" --kind news --max 8 --out md

B) Options / Flow (browser-first)

Unusual Whales frequently blocks scraping/headless access. So the recommended approach is: open the pages in a browser and summarize what you can see.

Quick link helper:

python3 scripts/options_links.py NVDA

Common URLs:

• https://unusualwhales.com/stock/{TICKER}/overview
• https://unusualwhales.com/live-options-flow?ticker_symbol={TICKER}
• https://unusualwhales.com/stock/{TICKER}/options-flow-history
