I think we have 2 possible scenarios here:
1) correction is over and we are entering the most profitable wave 3.
2) correction is in motion and we yet to reach end of the C wave. Then 70.80% level is to look up to.
Market decided that SUB should continue on the correction path.
The end of wave C should be between 70.80 and 78.60% (I'm leaning towards 70.80 but we will see how it goes).
