Zipline is a Pythonic, event-driven algorithmic trading library for backtesting strategies, originally built as the engine powering the Quantopian platform. It integrates with the PyData ecosystem (Pandas, NumPy, matplotlib, scikit-learn) and provides built-in statistics and historical data handling for strategy development.
Use cases
- backtest a trading strategy in python
- event-driven backtesting engine for quant strategies
- test a moving average crossover strategy on historical data
- simulate algorithmic trading strategies with pandas data
- python library for quantitative finance research
- compute performance statistics for trading algorithms
When to choose
- you want a mature, battle-tested Python backtester with PyData integration
- you are prototyping or researching trading strategies in Python
- you need built-in trading statistics like moving averages and regression within your algorithm
When to avoid
- you need live trading with modern broker integrations out of the box
- you require support for recent Python versions, as the original project targets older Python (2.7-3.6)
- you want an actively developed project - consider maintained forks like zipline-reloaded
