## ⚡ Quick Start

### 🔮 Stock Price Prediction with LSTM

Train a deep learning model to predict stock prices with just a few lines of code:

```python
from finlearner import DataLoader, TimeSeriesPredictor, Plotter

# 1. Fetch and preprocess data
df = DataLoader.download_data('AAPL', start='2020-01-01', end='2024-01-01')

# 2. Initialize and train the LSTM predictor
predictor = TimeSeriesPredictor(lookback_days=60)
predictor.fit(df, epochs=25, batch_size=32)

# 3. Generate predictions
predictions = predictor.predict(df)

# 4. Visualize results
Plotter.plot_prediction(df, predictions, title="Apple Stock Prediction")
```

### 💼 Portfolio Optimization (Markowitz)

Find the optimal asset allocation using Modern Portfolio Theory:

```python
from finlearner import PortfolioOptimizer

# Define your portfolio
tickers = ['AAPL', 'GOOG', 'MSFT', 'AMZN', 'TSLA']

# Run optimization with Monte Carlo simulation
optimizer = PortfolioOptimizer(tickers=tickers, start='2023-01-01', end='2024-01-01')
results, optimal_allocation, metrics = optimizer.optimize(num_portfolios=10000)

print("📊 Optimal Allocation (Max Sharpe Ratio):")
print(optimal_allocation)
print(f"\n📈 Expected Return: {metrics[1]:.2%}")
print(f"📉 Volatility: {metrics[0]:.2%}")
```

### 📊 Technical Analysis

Apply comprehensive technical indicators to your data:

```python
from finlearner import DataLoader, TechnicalIndicators, Plotter

# Load data
df = DataLoader.download_data('NVDA', start='2023-01-01', end='2024-01-01')

# Add all technical indicators at once
ti = TechnicalIndicators(df)
df_enriched = ti.add_all()  # Adds RSI, MACD, Bollinger Bands, ATR, Ichimoku, etc.

# Or add specific indicators
df = ti.rsi(window=14)
df = ti.macd(fast=12, slow=26, signal=9)
df = ti.bollinger_bands(window=20, num_std=2)

# Interactive candlestick chart
Plotter.candlestick(df_enriched, title="NVIDIA Technical Analysis")
```

### 🎯 Options Pricing (Black-Scholes-Merton)

Price European options and calculate Greeks:

```python
from finlearner.options import BlackScholesMerton

# Create option pricer
option = BlackScholesMerton(
    S=100,      # Spot price
    K=100,      # Strike price
    T=1,        # Time to maturity (years)
    r=0.05,     # Risk-free rate
    sigma=0.2,  # Volatility
    q=0.02      # Dividend yield
)

# Calculate prices
call_price = option.price('call')
put_price = option.price('put')

# Calculate Greeks
greeks = option.greeks('call')
print(f"Call Price: ${call_price:.2f}")
print(f"Delta: {greeks['delta']:.4f}")
print(f"Gamma: {greeks['gamma']:.4f}")
print(f"Vega: {greeks['vega']:.4f}")
```
