# Stock Information Explorer

This skill fetches OHLCV data from Yahoo Finance via `yfinance` and computes technical indicators **locally** (no API key required).

## Dependencies

Python packages (install once):

```bash
pip install yfinance rich pandas plotille
```

## Commands

**IMPORTANT:** Always use the `$SKILLS_ROOT` environment variable to locate scripts.

### 1) Real-time Quotes (`price`)

```bash
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" price TSLA
# shorthand
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" TSLA
```

### 2) Fundamental Summary (`fundamentals`)

```bash
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" fundamentals NVDA
```

### 3) ASCII Trend (`history`)

```bash
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" history AAPL 6mo
```

### 4) Professional Analysis (`pro`)

输出详细的技术指标文本分析报告。

```bash
# 基础分析（价格区间）
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" pro 002368.SZ 6mo

# 带技术指标
export PYTHONIOENCODING=utf-8
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" pro 002368.SZ 6mo --rsi --macd --bb
```

#### 可用指标 (optional)

- `--bb`  : Bollinger Bands(20,2) - 布林带

```bash
export PYTHONIOENCODING=utf-8
python "$SKILLS_ROOT/stock-explorer/scripts/quote.py" report 000660.KS 6mo
