Short answer : no official or unofficial connection known to date. Build something around the API
Long answer : since Ninja became a broker, you know that they cut off the openness of the platform and threw away all the various connection options of the past, except for the (now very) old licence holders.
Even for futures, Darwinex would have to negociate a partnership to become an official connection, or else the new licences could not even connect to something like CQG
https://ninjatools.studio/ This skilled guy will work on bridge requests if convinced of a commercial potential. Since the Darwinex API has a setup cost as an entry barrier, he might not see it. Maybe if a couple persons are interested. Btw, his solutions bypass the need for a NT licence.
