Elliott & Harmonics

Wave grammar and rules, plus the harmonic pattern catalog and its ratio system.

Two ratio-driven traditions share this family. Elliott Wave Theory reads the market as a repeating five-up, three-down wave cycle, nested across degrees; harmonic trading maps precise Fibonacci-ratio patterns (Gartley, bat, crab and their relatives) to potential reversal zones. Both descend from the same 1930s lineage of measuring crowd behavior with ratios, and both remain contested: their pages say honestly where the evidence is thin.
