HARMONIC PATTERN
Gartley pattern
A ratio-constrained XABCD retracement structure.
Rules visible before the outcome
- XA impulse and AB retracement
- BC and CD satisfy declared ratio bands
- D completes near the specified XA retracement
02 / CONFIRMATION
When the idea becomes eligible
A reversal trigger after the potential reversal zone is reached.
03 / INVALIDATION
What proves it wrong
Beyond the X point or a tighter D-zone rule.
The attractive mistake
Many overlapping ratios create multiple-testing and hindsight risk.
Make it falsifiable
Use fixed ratio bands and report rejected near-matches.
