QuantStart.com - QSTrader backtesting simulation engine.
copied from cf-staging / qstraderQSTrader is a free Python-based open-source modular schedule-driven backtesting framework for long-short equities and ETF based systematic trading strategies.
QSTrader can be best described as a loosely-coupled collection of modules for carrying out end-to-end backtests with realistic trading mechanics.
The default modules provide useful functionality for certain types of systematic trading strategies and can be utilised without modification. However the intent of QSTrader is for the users to extend, inherit or fully replace each module in order to provide custom functionality for their own use case.
