## Quick Start

### Finance Utilities

```python
from eetc_utils.finance import (
    calculate_optimal_leverage_kelly,
    intrinsic_value_using_dcf,
    garch_annualized_volatility,
    convert_daily_ohlc_data_to_weekly
)
import pandas as pd

# Calculate optimal leverage using Kelly Criterion
price_df = pd.DataFrame({
    'date': pd.date_range('2020-01-01', periods=200),
    'close': [100 + i * 0.5 for i in range(200)]
})

leverage = calculate_optimal_leverage_kelly(
    df=price_df,
    position_type="LONG",
    regime_start_date="2020-01-01",
    fractional_kelly_multiplier=0.5,
    use_garch=False
)

# DCF valuation
intrinsic_value = intrinsic_value_using_dcf(
    cash_flow=1000000000,
    growth_years=10,
    shares=100000000,
    growth_rate=1.15,
    beta=1.2
)

# Forecast volatility using GARCH
volatility = garch_annualized_volatility(price_df)

# Convert daily OHLC to weekly
weekly_df = convert_daily_ohlc_data_to_weekly(price_df)
```

### Options Trading

```python
from eetc_utils.options import (
    calculate_option_price_black_scholes,
    find_strikes_in_range,
    GEX,
    calculate_underlying_iv_from_option_iv
)

# Calculate Black-Scholes option price
call_price = calculate_option_price_black_scholes(
    right="C",
    und_price=100.0,
    strike=105.0,
    rate=0.05,
    tte=0.5,
    implied_vol=0.25,
    pv_dividend=0.0
)

# Find strike prices within a range
strikes = find_strikes_in_range(
    range_length_perc=0.1,
    price=100.0
)

# Calculate Gamma Exposure
gex = GEX(oi=1000, gamma=0.05)

# Convert option IV to underlying IV
underlying_iv = calculate_underlying_iv_from_option_iv(
    option_implied_vol=0.20,
    t=30/365
)
```

### EETC Data Hub Client

```python
from eetc_utils.clients.eetc_data import EETCDataClient
import os

# Initialize client (requires EETC_API_KEY environment variable)
client = EETCDataClient(api_key=os.getenv("EETC_API_KEY"))

# Fetch price data
price_data = client.get_price_data(symbol="AAPL", start_date="2024-01-01")

# Get fundamentals
fundamentals = client.get_fundamentals(symbol="AAPL")

# Fetch macroeconomic indicators
macro_data = client.get_macro_indicators(indicator="GDP", country="US")
```

### EETC Notifications Manager Client

```python
from eetc_utils.clients.eetc_notifications import EETCNotificationsClient
import os

# Initialize client (requires EETC_API_KEY environment variable)
client = EETCNotificationsClient(api_key=os.getenv("EETC_API_KEY"))

# Send trade update via Telegram
client.send_trade_update_to_telegram(msg="Shorted TSLA x100 at 1312.69.")
```


### Backtesting Framework

```python
from eetc_utils.strategy.backtesting.strategy import Strategy
from eetc_utils.strategy.backtesting.engine import BacktestEngine
import pandas as pd

class MyStrategy(Strategy):
    def on_start(self, context):
        self.position = 0

    def on_data(self, bar, context):
        # Simple moving average crossover
        if len(self.data) < 20:
            return

        sma_short = self.data['close'].tail(5).mean()
        sma_long = self.data['close'].tail(20).mean()

        if sma_short > sma_long and self.position == 0:
            context['place_order']('buy', quantity=100)
            self.position = 100
        elif sma_short < sma_long and self.position > 0:
            context['place_order']('sell', quantity=100)
            self.position = 0

    def on_stop(self, context):
        pass

# Load historical data
data = pd.read_csv("AAPL_historical.csv")

# Run backtest
engine = BacktestEngine(
    strategy=MyStrategy(),
    data=data,
    symbol="AAPL",
    initial_capital=100000,
    commission=0.001
)

results = engine.run()
print(f"Total Return: {results['total_return']:.2%}")
print(f"Sharpe Ratio: {results['sharpe_ratio']:.2f}")
print(f"Max Drawdown: {results['max_drawdown']:.2%}")
```

## Development

### Prerequisites
- Python 3.12+
- Poetry (for dependency management)

### Setup

```bash
# Install system dependencies
sudo apt-get install build-essential

# Install Python dependencies
make update_and_install_python_requirements
```

### Code Formatting

```bash
make reformat_code  # Uses black for consistent code style
```

### Testing

```bash
# Run all tests
python -m pytest tests/

# Run specific test file
python -m pytest tests/test_financials.py

# Run with coverage
python -m pytest tests/ --cov=src/eetc_utils
```

### Publishing to PyPI

#### Prerequisites

Create a `.pypirc` file in the project root with your PyPI API tokens:

```ini
[distutils]
index-servers =
  pypi
  testpypi

[testpypi]
repository = https://test.pypi.org/legacy/
username = __token__
password = pypi-YOUR_TEST_PYPI_TOKEN_HERE

[pypi]
repository = https://upload.pypi.org/legacy/
username = __token__
password = pypi-YOUR_PRODUCTION_PYPI_TOKEN_HERE
```

**Note**: The `.pypirc` file is already in `.gitignore` and will not be committed to version control.

To generate API tokens:
- **TestPyPI**: https://test.pypi.org/manage/account/token/
- **Production PyPI**: https://pypi.org/manage/account/token/

#### Publishing Steps

1. Update version in `pyproject.toml`:
   - Increment `version` field in `[tool.poetry]` section
   - Update dependencies in `[tool.poetry.dependencies]` if needed

2. Build the package:
   ```bash
   python -m build
   ```

3. Test on PyPI Test:
   ```bash
   make publish_package_on_pypi_test
   ```

4. Publish to production PyPI:
   ```bash
   make publish_package_on_pypi
   ```

The Makefile commands automatically read credentials from `.pypirc` and configure Poetry before publishing.

## Configuration

### Environment Variables
