In Germany one can trade since summer, 2016 on the stock market place Frankfurt, now this is not new.
It is really a Dualisting, however, according to presentation of Dko an alternative Listing should be checked in Q1 2017. For example, London.

So in Frankfurt one can act already much longer, why now the info in the 4/10/2017 came nobody understands.

Besides, trade hardly takes place on the stock market place.
