The German index DAX30 is testing the previous wave C (pink) bottom. The wave E has fallen deeper than expected and could invalidate the current triangle pattern if price manages to break below the support zone (blue box).
DAX is expanding a bearish correction via an ABC (blue) within wave Y (purple) and is now testing the bottom of wave C (pink). A bearish breakout indicates that a different wave pattern is valid. Either price is still in a wave C (pink) or the triangle could be a bearish pattern with a bearish break. A bullish bounce however could indicate the end of a wave E (pink) and start of the uptrend.
