Key Takeaways
- Elliott Wave organizes price swings by degree and by motive or corrective structure.
- The illustrated advance has five labeled legs with endpoints $112, $105, $132, $122 and $142 from a $100 start.
- Wave 2 retraces 58.33% of wave 1; wave 3 spans $27 and is longer than the $12 first and $20 fifth legs.
- Wave 4 ends at $122, above wave 1’s $112 high in this standard impulse outline.
- The following A–B–C path ends at $126, $134 and $116; the total retracement is 61.90% of the $42 advance.
What is Elliott Wave Theory?
Elliott Wave Theory is a technical analysis method that labels price swings as repeating motive and corrective structures, nested inside one another by degree. In a standard impulse, a trend advances in five waves, three with the trend and two against it, and a correction such as a zigzag or flat follows in three waves labeled A, B and C.
Each wave contains complete patterns at the next smaller degree, so the same move can be counted at several scales. Name the pattern and degree before applying its rules.
Impulse vs corrective waves
Motive patterns include impulses and diagonals. For a standard impulse, label five legs and inspect the 5–3–5–3–5 subdivisions: the second and fourth legs are corrective. Corrections include zigzags, flats, triangles and combinations. An Elliott triangle carries A–B–C–D–E labels.
A standard impulse also passes three checks: wave 2 retraces less than all of wave 1, wave 3 moves beyond wave 1 and is not the shortest of waves 1, 3 and 5, and wave 4 stays out of wave 1's price territory.
Formula
Upward wave 2 retracement = (P1 − P2) / (P1 − P0) × 100. Wave 4 retracement = (P3 − P4) / (P3 − P2) × 100.- P0 is the starting price; P1 through P5 are successive wave endpoints at the selected degree.
- Use the named leg’s own start and end prices for each retracement denominator.
- The example gives wave 2 = 7 / 12 = 58.33% and wave 4 = 10 / 27 = 37.04%.
- Measure percentage advances separately: wave 1 = 12%, wave 3 = 25.71%, wave 5 = 16.39%.
Elliott Wave example: checking the impulse rules
A stock bottoms at $100 and rallies to $112. It pulls back to $105, then advances to $132, pulls back to $122, and pushes to $142 before a three wave decline begins.
- Wave 1: $112 − $100 = $12
- Wave 2: ($112 − $105) / $12 = 58.33%
- Wave 3: $132 − $105 = $27; wave 5: $142 − $122 = $20
- Wave 4: ($132 − $122) / $27 = 37.04%; its $122 low stays above $112
- Advance: $142 − $100 = $42; subsequent correction: $142 − $116 = $26
- Full retracement: $26 / $42 = 61.90%; B retraces $8 / $16 = 50% of A
The labeled major swings pass the displayed retracement, length and overlap checks. The following A–B–C sequence reaches $126, $134 and $116. Label the finished advance in the larger count first: as a larger wave 1, it puts the invalidation level for the next scenario at $100.
Wave 1 spans $12. Wave 2 gives back $7, or 58.33%. Wave 3 spans $27 and exceeds the first leg; wave 5 spans $20. The respective percentage advances are 12%, 25.71% and 16.39%.
Wave 4 gives back $10 of wave 3's $27 advance, or 37.04%. Its $122 endpoint remains above wave 1's $112 high. The figure marks both lines: the $100 wave 2 origin and the $112 wave 4 boundary.
The following A, B and C endpoints are $126, $134 and $116. A spans $16 downward, B retraces $8 or 50%, and C spans $18 downward. The complete correction gives back $26 of the $42 advance, or 61.90%.
Invalidation levels for each wave count
During the illustrated second wave, $100 is the origin reference. During the standard impulse’s fourth wave, $112 marks wave 1's upper boundary. A chosen stop at $122 serves a separate trading rule.
After the advance completes, assign it a role in the next larger structure. Calling it larger wave 1 makes the $100 origin relevant to a proposed larger wave 2. Calling it a completed C or fifth wave establishes a different larger structure. Each label carries its own invalidation level, so write the level next to the count.
How traders use Elliott Wave with Fibonacci levels
The 61.8% retracement of the $100–$142 advance is $142 − 0.618 × $42 = $116.04. Compare that projection with the supplied $116 endpoint. Keep the 50% retracement fraction separate from Fibonacci-derived ratios.
Use Fibonacci Retracement and Fibonacci Extension for the price arithmetic, then define the entry, stop and objective for the chosen scenario. Test the count against Options Flow, where large orders leaning the same way back the scenario, and pair the objective with an expiration and volatility in the Options Profit Calculator to price each structure.
Limitations of Elliott Wave Theory
- Trade more than one count. The completed advance fits three counts, a larger wave 1, a completed C or a fifth wave, and each one points to a different next move, so plan each with its own level.
- Re-label as prices arrive. A count that fits today gets revised when price breaks its level, so every scenario carries its own invalidation price.
- Use the rules as exits for a count. A break below $112 during wave 4 rules out the standard impulse count, and the trade built on that count ends there; the next count needs its own setup.
- Treat Fibonacci levels as zones to watch. The example’s correction ended at $116, a 61.90% retracement against the $116.04 level at 61.8%, and corrections also end near 50% or elsewhere, so set the entry trigger on price rather than on the ratio.
- Set the entry, stop and size in the trading plan. The $122 trading stop and the $112 count boundary are separate levels: the stop caps the loss, and the boundary decides whether the count survives.
Bottom line
Elliott Wave Theory gives traders a vocabulary for labeling trends and corrections, plus rules that reject counts that break them. Use it to map alternative scenarios with clear invalidation levels, and set the entry, stop and size as separate trading decisions.
