## Usage Examples

### 1. Run Validation Backtest

```python
from nautilus_dolphin.validation import ValidationBacktestRunner

runner = ValidationBacktestRunner(
    eigenvalues_dir="/path/to/correlation_arb512/eigenvalues",
    output_dir="validation_results"
)

# Run all validation periods
results = runner.run_all_validations(
    assets=['BTCUSDT', 'ETHUSDT', 'BNBUSDT']
)

# Compare to VBT
from nautilus_dolphin.validation import VBTComparator, ReportGenerator

vbt_results = runner.load_vbt_results("vbt_baseline.json")
comparator = VBTComparator(vbt_results, results['high_volatility'])
report = comparator.compare()

# Generate reports
generator = ReportGenerator()
generator.save_reports(report)
```

### 2. Run Signal Generator

```python
import asyncio
from nautilus_dolphin.signal_generator import SignalGenerator

generator = SignalGenerator(
    eigenvalues_dir="/path/to/correlation_arb512/eigenvalues",
    redis_url="redis://localhost:6379",
    signal_interval_sec=5
)

asyncio.run(generator.start())
```

### 3. Run Paper Trading

```bash
# Configure
cp config/config.yaml config/config.paper.yaml
# Edit trading_mode: paper

# Start with Docker
docker-compose up -d

# Monitor
open http://localhost:3000  # Grafana
```

## Next Steps

### Pre-Production

1. **Validation Phase**:
   - Run validation backtests against 3 periods
   - Verify all metrics within tolerance
   - Generate validation reports

2. **Paper Trading**:

   - Run for 30 days minimum
   - Compare performance to backtest

3. **Security Audit**:
   - Review API key handling
   - Verify network security
   - Test backup/restore procedures

### Post-Production

1. **Monitoring**:
   - Tune alert thresholds
   - Add custom dashboards
   - Set up on-call rotation

2. **Optimization**:
   - Profile performance
   - Optimize latency bottlenecks
   - Scale if needed

3. **Documentation**:
   - Update runbooks with lessons learned
   - Document configuration changes
   - Maintain incident log
