JQuantLib provides a complete framework on valuation financial instruments, using a wide variety of algorithms. As it is written in Java, we plan to make it ready for the enterprise, splitting it in modules deployed under OSGi standards.

I absolutely agree with you, the future of trading systems is modular. I believe it is the best way to keep pace with innovations and changes in the market (regulatory or otherwise).

I also agree that developments of financial application have benefited tremendously of open source projects but few financial institutions are ready to share something back.

You’re absolutely right, it’s going to take a long time to be on a level with some of the commercial solutions in this space but I believe that this sector, more than many others, benefits massively from the open sharing of ideas and testing of solutions.

From my perspective, the traditional approach of installing a monolithic solution for end to end processing of derivatives trades causes many issues that could be solved by gradually building up an open, flexible and well engineered set of SOA components.

Thanks for the link.
