## Data Coverage

Provides 27 financial metrics per ticker across all categories: basic info, valuation ratios, earnings, profitability, growth, financial position, and market data. Uses Finviz and Yahoo Finance with automatic failover for high reliability.

## Configuration

### Environment Variables

```bash
# Custom storage location
export FINPULL_STORAGE_FILE="/path/to/custom/storage.json"

# Rate limiting (seconds between requests)
export FINPULL_RATE_LIMIT="2"

# Logging level (DEBUG, INFO, WARNING, ERROR)
export FINPULL_LOG_LEVEL="INFO"

# GUI theme (if supported)
export FINPULL_GUI_THEME="default"
```

### Storage

Data is persisted locally in JSON format with automatic backups:
- **Linux/macOS**: `~/.finpull/data.json`
- **Windows**: `%USERPROFILE%\.finpull\data.json`
- **Backup**: Automatic backup before major operations
- **Format**: Human-readable JSON with proper indentation

### Rate Limiting

Built-in intelligent rate limiting prevents API blocks:
- **Default**: 1 request per second (configurable)
- **Adaptive**: Automatically increases delays if rate limits detected
- **Burst Protection**: Prevents accidental rapid-fire requests
- **Source-Specific**: Different limits for different data sources

## Examples

### Portfolio Management

```python
from finpull import FinancialDataAPI

api = FinancialDataAPI()

# Build a technology portfolio
tech_stocks = ["AAPL", "GOOGL", "MSFT", "AMZN", "TSLA", "META", "NVDA"]
results = api.batch_add_tickers(tech_stocks)

print(f"Successfully added {results['summary']['added_count']} stocks")

# Analyze portfolio performance
portfolio_data = api.get_data()
for stock in portfolio_data['data']:
    print(f"{stock['ticker']}: ${stock['price']} | P/E: {stock['pe_ratio']} | Cap: {stock['market_cap']}")
```

### Automated CLI Workflow

```bash
#!/bin/bash

# Daily portfolio update script
echo "Updating portfolio..."

# Add new stocks if needed
finpull add AAPL GOOGL MSFT

# Refresh all data
finpull refresh

# Generate reports
finpull export "reports/portfolio_$(date +%Y%m%d)" --json --csv --xlsx

# Show summary
finpull show --full

echo "Portfolio update complete"
```

### Real-time Monitoring

```python
import time
from finpull import FinancialDataAPI

api = FinancialDataAPI()

# Add watchlist
watchlist = ["AAPL", "GOOGL", "MSFT", "TSLA"]
api.batch_add_tickers(watchlist)

while True:
    # Refresh data every 5 minutes
    api.refresh_data()
    
    # Check for significant changes
    data = api.get_data()
    for stock in data['data']:
        change_5y = float(stock['change_5y'].replace('%', ''))
        if abs(change_5y) > 10:  # More than 10% change
            print(f"Alert: {stock['ticker']} changed {change_5y}% over 5 years")
    
    time.sleep(300)  # 5 minutes
```

### GUI Automation

```python
import threading
from finpull import FinancialDataGUI

def setup_automated_gui():
    gui = FinancialDataGUI()
    
    # Pre-populate with data
    gui.scraper.add_ticker("AAPL")
    gui.scraper.add_ticker("GOOGL")
    gui.refresh_display()
    
    # Run GUI in separate thread
    gui_thread = threading.Thread(target=gui.run)
    gui_thread.start()
    
    return gui

# Launch automated GUI session
gui = setup_automated_gui()
```

### Error Handling & Logging

```python
import logging
from finpull import FinancialDataAPI

# Configure logging
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

api = FinancialDataAPI()

def safe_operation(ticker):
    try:
        result = api.add_ticker(ticker)
        if result['success']:
            logger.info(f"Successfully added {ticker}")
            return True
        else:
            logger.warning(f"Failed to add {ticker}: {result.get('error')}")
            return False
    except Exception as e:
        logger.error(f"Exception for {ticker}: {e}")
        return False

# Safe batch processing
tickers = ["AAPL", "INVALID", "GOOGL", "MSFT"]
successful = [t for t in tickers if safe_operation(t)]
print(f"Successfully processed {len(successful)}/{len(tickers)} tickers")
```
