the last file release is really outdated! if you are interested in the project i strongly recommend you to use the public CVS access.

i am currently in the process of switching from SISC/scheme to ABCL/CommonLisp. i am just to used to work in common lisp so that working in scheme is really a pain. luckily i found a really cool common lisp implementation in java: ABCL.

the next release of the project will be soon. i am currently doing the final cleaning work and polishing of details. the next release will be considered beta, because the classes and interfaces are stabilizing.

This is the first release of the OpenJavaTradingSystem. This release is meant to give you a first impression of what the project can do for you and where the project is going in the future. The project is a pure Java project and designed in such a way that you can easily integrate its functionality into your own applications.
