Jforex Programming languages

any participation is highly appreciated.
Iam still learning,
Jforex--especially with dukascopy, depends on java APIs, plus special Duka APIs.
so it has many interfaces, concrete and abstract classes to implement/extend three things:
interface IStrategy
interface IIndicator
class Plugin

You can start here [1]. JForex API is very flexible. You can have whole JForex platform running in your own process so using debugger is also possible.
