🚀 Quick Start

from quantflow import BlackScholes, RiskMetrics, MarketData

# Price options with full Greeks
option = BlackScholes(S=100, K=105, T=0.25, r=0.05, sigma=0.2)
print(f"Price: ${option.price():.2f}, Delta: {option.delta():.3f}")

# Analyze portfolio risk
data = MarketData.fetch_stock_data(['AAPL', 'MSFT'], period='1y')
returns = MarketData.calculate_returns(data)
risk = RiskMetrics(returns['AAPL'])
print(f"VaR (95%): {risk.var_historical(0.05):.2%}")
