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
