Are your options European? Or do they follow American rules? If they are traded in German stock exchange it sounds like European, but is there a way, hypothetically, to join another exchange if you aren't involved in the country of question in any other way?

They are European, they are actually warrants. They work the same as options but a lot less volume and you are mostly trading against the exchange. I think you need a European passport though to trade on a exchange here. But I'm not completely sure. 
  
 I mean I'm Dutch but my broker offers me these products created on the German exchange. There might even be American brokers that offer you the choice to buy from euro exchanges.
