Elliott Wave Theory

Elliott Wave Theory

Elliott Wave Theory interprets financial market price movements as recurring, fractal wave patterns driven by investor psychology. Developed by Ralph Nelson Elliott in the 1930s, it groups market action into motive (impulse) and corrective phases and uses wave relationships—often aligned with Fibonacci ratios—to help forecast likely price behavior. The method is probabilistic and subjective, so it is typically used alongside other technical tools and sound risk management.

Key takeaways

• Markets move in repeating wave structures that reflect collective investor sentiment.
• Motive (impulse) waves push with the larger trend and subdivide into five waves; corrective waves move against the larger trend and usually subdivide into three.
• Wave relationships often conform to Fibonacci ratios (e.g., 38%, 62%), which traders use to estimate targets and retracements.
• Elliott Wave analysis is subjective and not a guaranteed predictor; combine it with other indicators and risk controls.

Brief history

Ralph Nelson Elliott analyzed decades of market charts and proposed that price action unfolds in patterned waves. His rules and guidelines form the foundation used by many traders, analysts, and firms that apply wave-based forecasting.

Core principles

• Wave fractality: Waves of different degrees nest inside one another—short-term impulse waves can exist within a longer-term correction and vice versa.
• Two fundamental types:
• Motive (impulse) waves that move with the trend.
• Corrective waves that move against the trend.
• Investor psychology underpins wave formation: optimism and pessimism alternate and create the repeating structures Elliott described.

Impulse waves — structure and rules

An impulse wave contains five sub-waves (labelled 1–5) that move in the direction of the dominant trend. Typical characteristics and hard rules:
* Waves 1, 3, and 5 are motive; waves 2 and 4 are corrective.
* Wave 2 cannot retrace past the start of Wave 1.
* Wave 3 cannot be the shortest of waves 1, 3 and 5.
* Wave 4 should not overlap the price territory of Wave 1 (for standard impulses).
* Wave 5 often ends with momentum divergence (price makes a new high or low while an oscillator fails to do so).
If any of the strict rules are violated, the count should be reconsidered and potentially relabeled.

Corrective waves — common forms

Corrective waves typically move against the larger trend and often unfold as three-wave structures labelled A–B–C. Key points:
* Simple corrections commonly take the form A–B–C (three waves).
* Complex corrections can combine multiple simple corrective structures.
* Diagonals (leading or ending) are wedge-shaped patterns that can be five-wave structures resembling a contracting or expanding formation; subwave counts and characteristics vary by diagonal type.
* Corrective patterns are diverse; careful labeling is required because sub-wave counts and shapes differ by case.

Fibonacci relationships

Elliott observed frequent alignment between wave lengths and Fibonacci ratios. Typical applications:
* Use 38.2%, 50%, and 61.8% retracements to estimate where corrective waves may end.
* Projective ratios help estimate the length of Wave 3 or Wave 5 relative to Wave 1, etc.
These relationships are guidelines, not certainties, and are used in conjunction with wave counts.

Practical trading application

• Identify the current wave count and the degree (timeframe) you are analyzing.
• Trade with the trend during confirmed impulse waves (for example, enter on early waves of an up impulse).
• Expect a corrective A–B–C after a completed five-wave advance; consider taking profits or tightening stops near likely wave-5 terminations.
• Use other indicators (volume, moving averages, oscillators) and Fibonacci tools to confirm counts and timing.
• Maintain strict risk management—stop losses and position sizing—because wave labeling is inherently subjective.

Tools and automation

Analysts have developed tools that support Elliott analysis:
* Elliott Wave Oscillator (difference between short and longer moving averages) to help spot wave structure.
* Automated systems and AI (e.g., EWAVES-style engines) attempt to apply Elliott rules programmatically, but results depend on input rules and interpretation.

Limitations

• Subjectivity: different analysts may produce different wave counts for the same chart.
• No guarantees: patterns indicate probability, not certainty.
• Complexity: accurate application requires practice, awareness of multiple degrees, and frequent reassessment.

Conclusion

Elliott Wave Theory offers a structured way to interpret market cycles by mapping price action into motive and corrective waves. When combined with Fibonacci analysis, other technical indicators, and disciplined risk management, it can provide useful perspective on likely market directions—but its subjective nature requires caution and experience.
