Maybe is missing one wave to finished the wave C. The trend line is very important and the 835-840 area. Below this area the bears win this short term battle, until that the bull are winning.
This last movement was confused and unexpected so, keep in mind the trend line of my chart. I will considerate this movement like "missing wave e" of C. So i only will considerate that this movement is wave ii of iii of C when DAX broke the trend line.
