Question is... where are we right now? Looks like there are the next two possible scenarios to me:
1) Correction wave ( ABC ) in red has finished and we are in the impulse wave (orange), if this is the case, we should have topped 2nd wave heading to the 3rd down wave.
2) I tend to simplify correction waves (don't finish to understand ABCDE WXY) so we can still be in the correction wave ( ABC ) in blue. If this is the case we should be in the beginning of wave C. 300 area might be a that, if broken, could lead us to the red boxes area depending where wave 3 (green) ends.
Well, as always, we will just have to wait and see....
