## 🚀 Installation

```bash
pip install polars-talis
```

Or install from source:

```bash
git clone https://github.com/yourusername/polars-ta.git
cd polars-ta
pip install -e .
```

## 📖 Quick Start

```python
import polars as pl
from polars_talis import TechnicalAnalyzer, SMA, EMA, RSI, MACD, BollingerBands

# Load your data
df = pl.DataFrame({
    "date": ["2023-01-01", "2023-01-02", "2023-01-03"],  # Your dates
    "close": [100.0, 102.5, 101.8],  # Your price data
    "volume": [1000, 1200, 950]  # Your volume data
})

# Create analyzer with multiple indicators
analyzer = TechnicalAnalyzer(max_workers=4)
analyzer.add_indicators([
    SMA(20),           # 20-period Simple Moving Average
    EMA(12),           # 12-period Exponential Moving Average  
    RSI(14),           # 14-period RSI
    MACD(),            # MACD with default parameters
    BollingerBands(20, 2.0)  # 20-period BB with 2 std dev
])

# Calculate all indicators (parallel execution)
result = analyzer.calculate(df, parallel=True)

print(result.columns)
# ['date', 'close', 'volume', 'SMA_20', 'EMA_12', 'RSI_14', 'MACD', 'MACD_signal', 'BB_upper', 'BB_middle', 'BB_lower']
```

## 🔧 Advanced Usage

### Custom Indicator Configuration

```python
from polars_talis import SMA

# Custom column and name
sma_custom = SMA(period=50, column="high", name="SMA_High_50")

# Add to analyzer
analyzer.add_indicator(sma_custom)
```

### Performance Monitoring

```python
# Get summary of configured indicators
summary = analyzer.get_summary()
print(summary)
# {
#     'total_indicators': 5,
#     'by_type': {'trend': 2, 'momentum': 2, 'volatility': 1},
#     'indicators': [...]
# }
```

### Error Handling

```python
try:
    result = analyzer.calculate(df)
except ValueError as e:
    print(f"Data validation error: {e}")
except Exception as e:
    print(f"Calculation error: {e}")
```

## 🏗️ Architecture

Polars-Talis is built with a modular architecture:

```
polars_talis/
├── core/
│   ├── base.py          # Base classes and types
│   └── analyzer.py      # Main analyzer engine
└── indicators/
    ├── trend.py         # Trend indicators
    ├── momentum.py      # Momentum indicators
    └── volatility.py    # Volatility indicators
```

### Key Components

- **BaseIndicator**: Abstract base class for all indicators
- **IndicatorConfig**: Configuration dataclass for indicators
- **TechnicalAnalyzer**: Main engine for parallel indicator execution
- **IndicatorType**: Enumeration of indicator categories

## 📊 Visualizations

Polars-Talis comes with beautiful built-in visualizations to help you understand your technical analysis results:
