I'm glad to hear that it works. As for open sourcing the plugin, I can't promise anything.
The issue here is the Dukascopy pugin is not a standalone project. It's a small specific piece of code (only 400+ lines) running on top of a custom framework.
Open sourcing the plugin will mean to open source the whole my framework, which I'm not prepared to do at this moment.
Actually I would like to know when the Zorro project will be open sourced?
