Zipline Reloaded

Maintained fork of Quantopian's Zipline, an event-driven Python backtesting library

About Zipline Reloaded

Zipline Reloaded is a community-maintained continuation of the Zipline engine that powered Quantopian. It provides an event-driven backtester with a data bundle system and integrates with the Pyfolio and Alphalens analysis tools. It suits quant researchers who want a rigorous, equity-focused backtester but are willing to set up their own data.

Best for: Researchers building equity factor and portfolio strategies in Python.

Pros

  • Realistic event-driven engine
  • Works with Alphalens and Pyfolio
  • Open source

Cons

  • Data ingestion is fiddly
  • Setup and dependencies can be painful
  • Smaller community since Quantopian closed
