Introduction
# Stock Information Explorer
This skill fetches OHLCV data from Yahoo Finance via `yfinance` and computes technical indicators **locally** (no API key required).
## Commands
### 1) Real-time Quotes (`price`) ```bash uv run --script scripts/yf.py price TSLA # shorthand uv run --script scripts/yf.py TSLA ```
### 2) Fundamental Summary (`fundamentals`) ```bash uv run --script scripts/yf.py fundamentals NVDA ```
### 3) ASCII Trend (`history`) ```bash uv run --script scripts/yf.py history AAPL 6mo ```
### 4) Professional Chart (`pro`) Generates a high-resolution PNG chart. By default it includes **Volume** and **Moving Averages (MA5/20/60)**.
```bash # candle (default) uv run --script scripts/yf.py pro 000660.KS 6mo
# line uv run --script scripts/yf.py pro 000660.KS 6mo line ```
#### Indicators (optional) Add flags to include indicator panels/overlays.
```bash uv run --script scripts/yf.py pro TSLA 6mo --rsi --macd --bb uv run --script scripts/yf.py pro TSLA 6mo --vwap --atr ```
- `--rsi` : RSI(14) - `--macd`: MACD(12,26,9) - `--bb` : Bollinger Bands(20,2) - `--vwap`: VWAP (cumulative for the selected range) - `--atr` : ATR(14)
### 5) One-shot Report (`report`) ⭐ Prints a compact text summary (price + fundamentals + indicator signals) and automatically generates a **Pro chart with BB + RSI + MACD**.
```bash uv run --script scripts/yf.py report 000660.KS 6mo # output includes: CHART_PATH:/tmp/<...>.png ```
## Ticker Examples - US stocks: `AAPL`, `NVDA`, `TSLA` - KR stocks: `005930.KS`, `000660.KS` - Crypto: `BTC-USD`, `ETH-KRW` - Forex: `USDKRW=X`
## Notes / Limitations - Indicators are **computed locally** from price data (Yahoo does not reliably provide precomputed indicator series). - Data quality may vary by ticker/market (e.g., missing volume for some symbols).
