The 5-3 Elliott Wave Structure: Complete Rules for Impulse and Correction

The 5-3 structure is the foundation of Elliott Wave. Five waves in the direction of the larger trend (impulse), followed by three waves against it (correction). The edge comes from applying the rules strictly, not from loosely labeling waves that fit a preferred bias.

The impulse sequence (1-2-3-4-5).

• Wave 1: initial move in the new trend direction.
• Wave 2: retracement against wave 1, never beyond its origin.
• Wave 3: the powerful extension, usually the longest and never the shortest.
• Wave 4: sideways correction, never overlapping wave 1's price territory.
• Wave 5: final push in trend direction, often weaker than wave 3.

The three unbreakable impulse rules.

1. Wave 2 never retraces more than 100% of wave 1. If it does, the count is wrong.
2. Wave 3 is never the shortest of the three impulse waves (1, 3, 5). It can be the longest or the middle, but never shortest.
3. Wave 4 never enters the price territory of wave 1. A clean overlap invalidates the impulse count.

Break any one rule and you do not have an impulse. You have a corrective structure mislabeled as impulse. This is the single most common Elliott Wave error.

The correction sequence (A-B-C).

• Wave A: initial move against the prior impulse.
• Wave B: retracement back toward the impulse high/low, typically 50-79% of A.
• Wave C: continuation of A's direction, typically equal to A or 1.618x A.

Fibonacci relationships.

• Wave 2 commonly retraces 50% or 61.8% of wave 1.
• Wave 3 commonly extends to 1.618x or 2.618x of wave 1.
• Wave 4 commonly retraces 38.2% of wave 3.
• Wave C commonly equals wave A or extends to 1.618x A.

Guideline of alternation. If wave 2 was a sharp correction, expect wave 4 to be a flat or sideways correction, and vice versa. This is a guideline, not a rule, but it holds roughly 70% of the time and helps anticipate wave 4's character.

Guideline of equality. When wave 3 is extended (the most common case), waves 1 and 5 tend toward equality in price and time. If wave 1 traveled 100 points, expect wave 5 near 100 points unless it truncates or extends.

Invalidation discipline. Every wave count needs a specific price level that proves it wrong. If wave 2 retraces beyond wave 1's origin, the bullish count is dead. If wave 4 overlaps wave 1, the impulse is dead. Without invalidation levels, wave counting becomes unfalsifiable storytelling.

The starting point trap. Do not begin counting waves in the middle of a move. Confirm the prior trend direction first, identify a clear origin, then count forward. Starting mid-move produces counts that fit anything and predict nothing.
