TECHNICAL DETAILS
================================================================================
Data Source: Yahoo Finance (yfinance) - Free, no API key
Models: LSTM (simulated), ARIMA (AR5), Naive, Moving Average
Horizons: 1-day, 5-day, 20-day predictions
Uncertainty: 95% confidence intervals via historical volatility
Backtesting: Walk-forward validation (prevents overfitting)
Performance: ARIMA typically best for short-term (<5 days)
