I wouldn't put any weigh at all on price movement on the German exchange.
It is extremely illiquid. There was a total of 16000 shares in volume traded overnight. The current spread in depth shows it. There is only one buyer of 12000 for 0.089c and one seller of 6000 for 0.185.
At this point in time there appears little interest in the company on that exchange.
Any price movements there are irrelevant until it becomes a liquid market.
