Ranked by Pattern Confidence

Counts ending at the latest intermediate swing low, 138.80 on Oct 5, 2026. 146 labelings tested, 98 broke a hard rule, 12+ remain.

Hard-rule evidence: why 98 labelings were eliminated

45Wave 2 always retraces less than 100% of wave 1
20Contracting triangle: C ends short of A's end, D short of B's end, and E short of C's end
18Wave 3 always travels beyond the end of wave 1
6Wave B ends short of the start of wave A (a zigzag is a sharp correction)
5Wave B retraces at least 90% of wave A
3Wave 4 always retraces less than 100% of wave 3

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.

Daily chart, as of Oct 16, 2026

Since the count's last pivot (138.80, Oct 5, 2026) price has moved +5.2%, the way the count expects.12 of 12 rule-valid counts expect the current move to be up.Weekly count: flat wave C ↑, same direction

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 · 6 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)
Wave C travels beyond the end of wave A (a failure is a truncation)
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
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.
