We just missed the .786 retrace shown. If we continue to rise from here, target will be 3657 + 343 = 4000 exactly (coincidence??) on 2-18-21.
If we head down again to kiss that retrace of 3653, estimate to head up will be 3996 on the same date.
After that, watch out, and because it seems too obvious, I would be on the defensive long before that point because I would imagine we could see a dumping at any point moving forward.
This is only an estimate of events to unfold.
