Rather than talk about how much better JFUtil 2.0 is and all, I'll just show you a demonstration strategy illustrating the features of this JForex utilities library. Download the latest JFUtil from the project page. As this is an alpha release, I need your help in finding bugs and look for improvements. Leave me a message if you have any comment or suggestion please. It's best if you copy and paste the following demo strategy source code into your IDE or text editor for viewing.
