Pythonic event-driven system for backtesting algorithmic trading strategies.

Zipline is an open-source Python library for backtesting trading algorithms. It provides an event-driven system that simulates live trading using historical data. The core architecture involves ingesting historical market data (pricing, volume) into a data panel. User-defined algorithms consume this data, generate orders, and the system simulates the execution of these orders. Zipline integrates with the PyData ecosystem, using Pandas DataFrames for data input and output, facilitating interoperability with libraries like NumPy, SciPy, and scikit-learn for advanced statistical analysis and machine learning applications. It supports various order types and risk management strategies. Zipline Reloaded aims to keep the library updated and compatible with modern Python versions and libraries.

Allows users to ingest data from various sources beyond the standard Quandl integration, accommodating proprietary or alternative datasets.
Integrates with optimization libraries (e.g., SciPy) to dynamically allocate capital across assets based on risk-adjusted return profiles.
Processes market events in real-time, enabling algorithms to react instantly to changing conditions.
Supports implementation of advanced order types beyond market and limit orders, such as VWAP, TWAP, and smart order routing algorithms.
Facilitates integration with machine learning libraries (e.g., scikit-learn, TensorFlow) for predictive modeling and algorithmic strategy development.
Install Zipline using pip or conda.
Ingest historical market data using the Zipline CLI with a data provider like Quandl (requires API key).
Define an initialization function to set up the algorithm's context.
Implement a handle_data function that contains the trading logic.
Run the algorithm using the Zipline CLI, specifying the start and end dates, and output file.
