What it does

A Python library for backtesting options strategies such as iron condors and spreads on historical option chain data, with risk metrics and portfolio simulation.

Adopt it when

You research options trading strategies in Python and already have historical option chain data.

Watch out

It is AGPL-3.0, you must source option data yourself, and backtest results are not a guide to live returns.
