PyAlgoTrade is a Python library that I started with one simple goal in mind: To make it easy backtest stock trading strategies.
That is, given a certain amount of historical data for one stock, I want to check how a certain stock trading strategy behaves. It should also make it easy to optimize a strategy using multiple computers.
PyAlgoTrade was developed with Python 2.7 and depends on NumPy and SciPy, so you need to have those installed in order to use this library.
