Backtesting Framework

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+
• uv (for dependency management, packaging, and publishing)

Setup

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

# Install Python dependencies
make install_python_requirements

Code Formatting

make reformat_code  # Uses black for consistent code style

Testing

# 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:

[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 the [project] section
   • Update dependencies in [project.dependencies] (or [dependency-groups] for dev tools) if needed

2. Build the package:

   uv build
   

3. Test on PyPI Test:

   make publish_package_on_pypi_test
   

4. Publish to production PyPI:

   make publish_package_on_pypi
   

The Makefile commands automatically read credentials from .pypirc and pass them to uv publish via the UV_PUBLISH_TOKEN environment variable.

Configuration

Environment Variables

• EETC_API_KEY: API key for EETC Data Hub client (required for data access)
