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

No rule-valid wave count at intermediate degree

SBND needs more confirmed swings before any labeling can pass the rules. Viridia shows no wave label rather than a guess.

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.

Candidate interpretations

Unranked

Appears once daily bars are stored.

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.

Fibonacci map

Confluence zones above and below the close

Appears once daily bars are stored.

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

No scenario at intermediate degree right now

A scenario needs the preferred count to define an invalidation and a structural target on opposite sides of the reference level. 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.
