Unmaintained vectorized pandas backtesting framework
What it is
A vectorized backtesting framework built on pandas, kept as an early research-oriented design. Signals and positions are expressed as pandas series, which makes the basic mechanics of a vectorized backtest easy to read. Researchers who want to understand how such a backtester works under the hood can learn from the code. It is no longer maintained, so new projects should choose an actively developed framework instead.
