A positive PowerShift signal occurs when a security has become severely oversold and strengthens enough to potentially break the decline. Positive PowerShift signals are marked by a rising wedge with a green core plotted beneath the day on which they occurred.
A negative PowerShift signal is just the opposite of a positive PowerShift with a small variation in the logic and is marked by a falling wedge with a red core plotted above the day on which it occurred.
A negative Pivot occurs when a severely oversold security strengthens and then fails. A pivot sell is marked by a red minus sign plotted above the day it occurs.
A positive Pivot is the reverse of a negative Pivot, again with a small change in the logic, and is marked with a green plus beneath the day on which it occurred.
There is a difference in the logic between the positive and negative signals, based upon the idea that declines generally precede at a faster pace than advances. (The old saw goes, "Down is faster!")
Pivots usually, but not necessarily, occur after PowerShifts. Conceptually Pivots are companions to PowerShifts and should mark reaction highs after important lows and vice versa. An idealized chart is presented below.
For daily charts, a PowerShift or Pivot may appear on the current day, however the signal is not confirmed until the close.
Weekly signals are calculated at end-of-week. Any weekly signal appearing for the current week is not yet a confirmed PowerShift or Pivot.
