Confirming rate of change divergences with price

Treat momentum as an oscillator family and read a weaker rate-of-change extreme against a later price extreme as a divergence alert. The archive workflow is complete only after a price-confirmation event.

  • Size the rate-of-change window and the spacing of disagreements to the swing under study.
  • Treat a price and oscillator disagreement as an alert, not as a completed reversal.
  • Wait for a price-confirmation event, such as a completed pattern, a moving-average crossover, or a trendline break.
  • Score significance by the number of disagreements, their spacing in time, and how close the last oscillator reading sits to the equilibrium level.

Momentum as a family of oscillators

Momentum is used as a generic label for oscillators that track the speed or change of price rather than the price level itself. Rate of change is one such construction: it compares the latest price with the price a fixed number of periods earlier. Disagreement between that series and price is treated as a core reading rule.

How a divergence is classified

An oscillator can crest or trough before price. A later price extreme against an earlier, weaker oscillator extreme is classified as a divergence.

Price making a later high while the oscillator prints a weaker peak is a negative divergence, so the advance is losing thrust. Price making a later low while the oscillator prints a higher trough is a positive divergence, so the decline is losing thrust.

Disagreements at peaks are described as more common and typically leading by more time than those at troughs. Trough cases still occur and are labeled positive.

Price confirmation completes the reading

A divergence is not treated as a completed reversal. The procedure waits for a price-confirmation event taken from price itself, such as a pattern completion, a moving-average crossover, or a trendline break.

Several disagreements can unwind without a trend change, so a rule that acts on the oscillator alert alone is specified as incomplete.

Three construction checks

Significance is scored with three construction checks: how many disagreements appear, how far apart they sit in time, and how close the last oscillator reading is to its equilibrium level. The equilibrium level is the oscillator baseline, often the zero line on a rate-of-change series, used to judge how much thrust remains at the last disagreement.

Match the window to the swing

Oscillator length and the spacing of disagreements are supposed to match the swing under study, from short-term windows to intermediate spans of six weeks to nine months and primary spans of nine months to two years.

A walking series still waits for price

A rate-of-change series that keeps deteriorating while price merely stalls can be handled like a formal lower-low divergence for alert purposes. That walking series is still awaiting a price break.

CRB Spot Raw Industrials 13-week rate of change, 1992–1997

After the 1994–95 advance, later 13-week rate-of-change peaks keep shrinking — from about 11 down toward 4 — while the CRB Spot Raw Industrials index stops making new headway. That downhill walk is only an alert: the 1993 sequence was later confirmed by a price upturn, but the 1995–97 fade never received a confirming break. The series was read from the published two-pane chart; the article prints no table of values.

Approximate readings from the printed chart, to the nearest half-point. Pring notes the 1995–97 episode is not a strict lower-low divergence because the last oscillator low sits near its two predecessors.

A last disagreement near equilibrium

When the last disagreement occurs near the oscillator's equilibrium level or zero line and price then confirms, the construction is presented as a warning to expect a larger-than-usual subsequent move. That outcome is not treated as certain.
