QuantComponents is a framework for financial time-series analysis and algorithmic trading, based on Java and OSGi, with an Eclipse front-end. It is highly modular: usable as a plain Java API, OSGi components, or integrated into Eclipse. It works standalone or with a client-server architecture, depending on performance and reliability needs, and is integrated with Interactive Brokers through the IB Java API. Its generic broker API means that it can easily be extended to work with other brokers. A backtesting facility and an extensible SWT charting library are provided.
