after sell off a small relief rally up?

FX:GER30   DAX Index
dax has broken its weekly trendline and sell off followed smashing through levels making me think that the 12000 level is nearing in the following weeks. with such a big sell off a rebound back to the low of the previous range at 12305 is somewhere i want to be testing short play. to me there is a gap in profile to fill downwards in the dax making me think that 12000 is the key to start long plays
