Ranked by Pattern Confidence

Counts ending at the latest intermediate swing high, 21.24 on Sep 22, 2026. 172 labelings tested, 128 broke a hard rule, 12+ remain.

Hard-rule evidence: why 128 labelings were eliminated

63Wave 2 always retraces less than 100% of wave 1
15Contracting triangle: C ends short of A's end, D short of B's end, and E short of C's end
11Price after the last labeled point has not crossed a rule-based invalidation level
9Wave 3 always travels beyond the end of wave 1
8Wave B ends short of the start of wave A (a zigzag is a sharp correction)
6Wave 4 always retraces less than 100% of wave 3

Method Every chain of 3–6 alternating pivots ending at the latest confirmed pivot is tested as each pattern; only counts with zero hard-rule failures are kept, then ranked by Pattern Confidence.

Method Targets come from the Fibonacci relationships the sources describe for the wave in progress, Elliott trend channels, the prior fourth wave of lesser degree, and 38.2–78.6% retracements of the latest swing. A zone is where two or more independent relationships fall within max(¼ ATR, 0.4%) of each other; strength counts them, weighting primary ratios and higher degrees. It is not a probability.

Setup

Intermediate degree · from the preferred count

The intermediate-degree scenario was held back

Its levels didn't pass Viridia's checks: invalidation over 25% away. It's listed for review instead of shown.

NoteResearch scenario generated from Viridia's structural model. Not a recommendation.MethodA setup restates the preferred count as a trade: the entry (the close, or the level where the correction in progress most often ends), the stop where the count is wrong (a rule level, or the end of a finished pattern), and the count's own Fibonacci target. Reward:risk is measured from the middle of the entry range. A setup needs reward:risk of at least 1 : 1. It is research output from the wave count, not a recommendation or a forecast.

MethodStructure: the intermediate-degree swing structure (higher highs and lows, lower highs and lows, expanding or contracting). Wave: the preferred daily wave count's expected direction (constructive up, defensive down), unresolved when the alternate is within 5 points. Fibonacci: the nearest confluence zone of Fibonacci relationships and the distance to it (inside, or within 3%, counts as at a zone). Regime: price against its 50- and 200-day averages. Momentum: 3-month return and its lead over SPY (strong when both are positive and the lead is over 5 points; weak when both are negative). Risk: 20-day volatility against the 1-year level (elevated above 1.25×), and the 1-year drawdown and beta to SPY.

Structure at a glance

Daily chart, as of Oct 20, 2026

Since the count's last pivot (21.24, Sep 22, 2026) price has moved −22.1%, the way the count expects.12 of 12 rule-valid counts expect the current move to be down.Weekly count: zigzag wave C ↑, opposite direction

Preferred count

Zigzag up · complete, next move down ↓

A three-wave zigzag correction up looks complete, so the larger trend would normally resume down.

3 of 3 checks met

Why this count is preferred · 6 met, 0 not met

Met

Wave B retraces 38.2% to 85.4% of wave A
Wave B retraces under 90% of wave A (deeper B waves fit a flat better)
Wave C travels beyond the end of wave A (a failure is a truncation)
Wave C equals 61.8%, 100% or 123.6% of wave A
Alternate waves are related by a Fibonacci ratio within 5% (wave 5 to wave 1, C to A, or triangle legs at 61.8%), the more reliable kind of relationship
The count starts at the price extreme of the prior swing (a new trend begins where the old one ended)

Not met

None.

MethodPattern Confidence = (guidelines met + 2) ÷ (guidelines measured + 4), from the rulebook's guidelines, Fibonacci tendencies and wave-personality checks (wave 3 speed and volume, wave 5 volume, alternation in time, a start at the prior extreme), alternate waves in Fibonacci ratio, and the rarity of running flats. The alternate is the best-ranked count that tells a different story. It ranks the rule-valid counts against each other; it is not a probability of any outcome.
