Learn impulse and corrective wave structure

Overview

Elliott Wave Theory divides price movements into two fundamental structures: impulse waves (motive, 5-wave directional moves) and corrective waves (counter-trend, 3-wave retracements). Understanding these patterns allows traders to identify where the market is in its cycle and forecast probable next moves.

Impulse Wave Structure (5-Wave Motive)

Structural Rules (These MUST Hold)

1. Wave 2 cannot retrace more than 100% of wave 1 (it can't go below wave 1's start)
2. Wave 3 is NEVER the shortest among waves 1, 3, 5 (usually the longest)
3. Wave 4 cannot overlap wave 1's price territory (except in diagonals)

WHY these rules? They enforce the "trend integrity" idea. If wave 2 retraces 100%+, there's no net progress = not an impulse. If wave 4 overlaps wave 1, the structure looks corrective (ABC), not motive. These rules filter out random noise from true Elliott patterns.

Deriving the 5-Wave Logic

Start from human behavior:

• Wave 1: Early adopters enter (new trend starts, low volume, skepticism)
• Wave 2: Profit-taking, doubt—price retraces but doesn't kill the move (confidence building)
• Wave 3: Mainstream recognition, FOMO kicks in—longest, strongest wave (high volume, media coverage)
• Wave 4: Pause for profit-taking again, but belief in trend persists (shallower than wave 2)
• Wave 5: Final push by latecomers, often weaker (divergence indicators), exhaustion sets in

Each sub-wave reflects a different cohort of market participants entering/exiting.

WHY Fibonacci? Elliott observed that market waves cluster around ratios found in natural growth patterns (golden ratio φ≈ 1.618). Wave 3 "extends" because of exponential participation growth—mathematically, if each new cohort is ~1.618× the prior, you get these ratios. It's an empirical observation hardened into guideline.

Scenario: Stock at ₹100 starts uptrend.

• Wave 1: Rises ₹100 → ₹120 (+20 points)
  • Why? Early smart money accumulates.
• Wave 2: Drops ₹120 → ₹110 (-10 points, 50% retrace)
  • Why this level? 50% sits at the lower edge of the typical 50%–61.8% zone, testing the resolve of wave 1 buyers.
  • Why not to ₹100? That would be 100% retrace = rule violation.
• Wave 3: Surges ₹110 → ₹142 (+32 points, 1.6× wave 1)
  • Why strongest? Institutional buying, breakout confirmation, volume spike.
  • Check: 32 > 20 (wave 1) ✓ and we expect 32 > wave 5 ✓ (wave 3 not shortest).
• Wave 4: Retraces ₹142 → ₹134 (-8 points, 25% of wave 3)
  • Why shallow? Strong hands hold, only weak profit-takers exit.
  • Check: ₹134 > ₹120 (wave 1 high) ✓ no overlap.
• Wave 5: Final push ₹134 → ₹154 (+20 points, = wave 1 length)
  • Why equals wave 1? Common "equality" relationship when wave 3 extended.
  • Sign of exhaustion: RSI divergence (price higher, RSI lower).

Net move: ₹100 → ₹154 (+54 points in 5 waves)

Corrective Wave Structure (3-Wave A-B-C)

Types of Corrections

1. Zigzag (5-3-5): Sharp, steep retracement. Wave A is 5 sub-waves, B is 3, C is 5. Looks like a lightning bolt.
2. Flat (3-3-5): Sideways. Wave A is 3, B retraces ~100% of A (goes back to start), C extends slightly beyond A's end.
3. Triangle (3-3-3-3-3): Converging waves (A-B-C-D-E, five legs), each leg subdividing into 3 sub-waves. Indicates consolidation before the final impulse wave.

WHY 3 waves? Corrections are "incomplete"—they don't have the full 5-wave conviction of a trend. The market wants to resume the main trend, so corrections are shorter, choppier, less orderly.

Deriving ABC Logic

• Wave A: First leg down (or up in downtrend correction). Traders think "maybe just profit-taking."
• Wave B: Bounce/rally. "False hope" that trend resumes—but it fails (B doesn't make new high/low).
• Wave C: Final purge. Stops hit, capitulation. Often extends to 1.0× or 1.618× length of wave A.

The 3-wave structure reflects incomplete psychology: some participants exit (A), some re-enter hoping trend continues (B), then everyone realizes the correction isn't done and final exit (C).

Scenario: After ₹100 → ₹154 impulse (from prior example), market corrects.

• Wave A: Drops ₹154 → ₹136 (-18 points, about 33% of impulse)
  • Why? Profit-booking after wave 5. Moves in 5 sub-waves (impulsive down).
• Wave B: Bounces ₹136 → ₹147 (+11 points, ~61% retrace of A)
  • Why? Late bulls still buying, thinking uptrend resumes. Moves in 3 sub-waves (corrective up).
  • Why ~61%? This sits right at the 61.8% upper edge of the zigzag B-wave guideline (50%–61.8%).
  • Check: ₹147 < ₹154 (doesn't exceed wave 5 high) ✓
• Wave C: Drops ₹147 → ₹125 (-22 points, 1.22× wave A)
  • Why? Realizes correction not done, final sellers exit. Moves in 5 sub-waves.
  • Common target: ₹154 - (1.618 × 18) ≈ ₹125, matching ✓

Net correction: ₹154 → ₹125 (-29 points, ~54% of the ₹54 impulse gain). Market now ready for next impulse up.

The 5 big steps (impulse wave) are when you're really climbing: step 1 = start, step 2 = slip a bit (but not all the way down), step 3 = huge leap (you're feeling strong!), step 4 = tiny rest, step 5 = final push to a ledge. These 5 steps have rules, like "step 3 can't be the weakest" and "step 4 can't go below where step 1 started" (because then you'd be going backward, not forward).

The 3 steps back (corrective wave) are when you rest and slide down a little: A = slide down, B = try to climb back up a bit, C = slide down again. It's only 3 steps because you're not really trying to go down—you're just catching your breath before the next 5-step climb.

Every time you zoom in on one of those steps, you see the same pattern again (5 small steps inside each big step)—it's like a fractal! And the distances you move? They follow a magic number pattern called Fibonacci (like 1, 1.618, 0.618) that shows up in nature, like in sunflowers and seashells. So the market "breathes" in this 5-forward, 3-back rhythm because people's emotions (excitement and fear) create that pattern over and over.
