only wave B can (wave 2 cannot) retrace more than 100 %.Wave A is internally an abc
completed at 8251 with 194 points,Wave B is an irregular abc with an extended c
completed at 7894 with 357 points, and C is always an impulse wave, is progressing now.
if my assumptions are right,then the C must go minimum 8275.
The internal structure is stable in supporting the view.
