Ranked by Pattern Confidence

Counts ending at the latest intermediate swing low, 16.05 on Oct 2, 2026. 144 labelings tested, 107 broke a hard rule, 12+ remain.

Hard-rule evidence: why 107 labelings were eliminated

60Wave 2 always retraces less than 100% of wave 1
18Contracting triangle: C ends short of A's end, D short of B's end, and E short of C's end
15Wave 4 always retraces less than 100% of wave 3
7Wave B ends short of the start of wave A (a zigzag is a sharp correction)
3Wave B retraces at least 90% of wave A
2Contracting diagonal: wave 3 is shorter than wave 1, wave 5 shorter than wave 3, and wave 4 shorter than wave 2

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.

Evidence

The setup the preferred count implies, and how that kind of setup has done

Setup

Intermediate degree · from the preferred count

No scenario at intermediate degree right now

The target is closer than the stop (reward:risk 0.16 : 1): most of the count's expected move has already happened, so it isn't a setup. Viridia shows nothing rather than a guess.

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 16, 2026

Since the count's last pivot (16.05, Oct 2, 2026) price has moved +11.5%, the way the count expects.12 of 12 rule-valid counts expect the current move to be up.Weekly count: zigzag wave C ↑, same direction

Preferred count

Flat down · complete, next move up ↑

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

2 of 3 checks met

Why this count is preferred · 4 met, 1 not met

Met

Wave C ends slightly beyond wave A (regular), substantially beyond (expanded), or short of it after an extended B (running)
Wave C measures 61.8% to 161.8% of wave A, depending on the flat type
The flat is a regular or expanded flat; running flats are a rare variation
The count starts at the price extreme of the prior swing (a new trend begins where the old one ended)

Not met

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

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.
