Counts ending at the latest intermediate swing low, 108.77 on Sep 3, 2026. 118 labelings tested, 84 broke a hard rule, 12+ remain.

Hard-rule evidence: why 84 labelings were eliminated

21Wave 3 always travels beyond the end of wave 1

4Wave B retraces at least 90% of wave A
4Wave B ends short of the start of wave A (a zigzag is a sharp correction)
3Wave 4 always retraces less than 100% of wave 3

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.

Track record: this setup reached its target first in 19% of 2,346 past cases, averaging +0.18R. It made money in both halves of the replay (+0.18R, then +0.19R). Method

Counter-trend trade: wave C ends the correction, after which the larger trend resumes.
Close call: the alternate count scores within a few points of the preferred one.

Followed for up to 60 sessions in the track record.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.

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.

Why this count is preferred · 3 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)
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.
