Candidate interpretations

Ranked by Pattern Confidence

Counts ending at the latest minor swing high, 25.65 on May 27, 2026. 6 labelings tested, 4 broke a hard rule, 2 remain.

Hard-rule evidence: why 4 labelings were eliminated

3Wave 2 always retraces less than 100% of wave 1
1Wave B ends short of the start of wave A (a zigzag is a sharp correction)

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. Rules: rulebook.Engine pivots-1.0.0+rules-1.0.0+candidates-1.0.0+fib-1.0.1+rank-1.1.0+setup-1.0.1, bars to Oct 16, 2026

Fibonacci map

Confluence zones above and below the closeClose 24.76

No price band within 35% of the close has two or more independent Fibonacci relationships.

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

Minor degree · from the preferred count

No scenario at minor degree right now

The rules set no stop for the wave in progress, so there is no defined risk. 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.

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

Met

None.

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.
