pybacktest

Simple yet powerful backtesting framework in python/pandas.

Currently I don't plan to continue working on this project.

About

It allows user to specify trading strategies using full power of pandas, at the same time hiding all boring things like manually calculating trades, equity, performance statistics and creating visualizations. Resulting strategy code is usable both in research and production setting.

Strategies could be defined as simple this:

ms = pandas.rolling_mean(ohlc.C, 50)
ml = pandas.rolling_mean(ohlc.C, 100)
buy = cover = (ms > ml) & (ms.shift() < ml.shift())
sell = short = (ms < ml) & (ms.shift() > ml.shift())

And then tested like this: pybacktest.Backtest(locals())

We use it in our research and production operations.

Installation

pip install git+https://github.com/ematvey/pybacktest.git

If you don't install it in virtualenv, you might need to prepend last line with sudo.

Tutorial

Tutorials are provided as ipython notebooks in folder examples. You run it from cloned repo or watch via nbviewer.

Status

Single-security backtester is ready. Multi-security testing could be implemented by running single-sec backtests and then combining equity. Later we will add easier way.
