Ranked by Pattern Confidence

Counts ending at the latest intermediate swing low, 9.93 on Oct 1, 2026. 116 labelings tested, 92 broke a hard rule, 12+ remain.

Hard-rule evidence: why 92 labelings were eliminated

33Wave 2 always retraces less than 100% of wave 1
24Wave 3 always travels beyond the end of wave 1
14Contracting triangle: C ends short of A's end, D short of B's end, and E short of C's end
9Wave 4 always retraces less than 100% of wave 3
4Wave B ends short of the start of wave A (a zigzag is a sharp correction)
3Wave B retraces at least 90% of wave A

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.

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. 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.

Preferred count

Zigzag down · complete, next move up ↑

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

Why this count is preferred · 4 met, 2 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)
The count starts at the price extreme of the prior swing (a new trend begins where the old one ended)

Not met

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

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.
