Ich will ja auch gar nichts gesagt haben :-)

Ich glaube, so langsam kriege ich den Dreh raus.
Habe mir mal einen EA gebaut, der guckt ob für 5 hintereinanderfolgende Balken sich der Abstand von oberer Linie zu Mittellinie koninuierlich verringert :-)

Sowie eine Funktion, die mir bei jedem balken anzeigt wie sich prozentual der Abstand verändert hat :-)
