HARMONIC PATTERN
ABCD measured move
A four-point swing sequence used to research symmetry and proportional legs.
Rules visible before the outcome
- Three alternating legs form A-B-C-D
- AB and CD length tolerance is fixed
- BC retracement range is predefined
02 / CONFIRMATION
When the idea becomes eligible
A reaction at D plus an objective close or structural shift.
03 / INVALIDATION
What proves it wrong
Beyond D by a declared price or ATR tolerance.
The attractive mistake
Flexible ratios make almost any swing sequence fit after the fact.
Make it falsifiable
Compare Fibonacci tolerances with simple equal-leg controls.
