## Requirements
- bash 4+
- python3 (standard library only)

## Commands

### calculate
Calculate MACD from a comma-separated price series.
```bash
bash scripts/script.sh calculate "170.5,171.2,172.8,171.0,173.5,174.2,175.0,174.8,176.1,175.5,177.2,178.0,176.5,177.8,179.0,178.5,180.2,179.8,181.0,180.5,182.3,181.8,183.0,182.5,184.0,183.5"
```

### calculate-file
Calculate MACD from a CSV file (one price per line or column).
```bash
bash scripts/script.sh calculate-file prices.csv
```

### interpret
Interpret MACD, signal, and histogram values with trading signals.
```bash
bash scripts/script.sh interpret 1.25 0.80
