In this article, you will learn how to identify and trade Elliott Wave Extensions within impulsive structures. One of the core rules of Elliott Wave Theory states that in a 5-wave structure, Wave 3 cannot be the shortest. However, this doesn’t always mean Wave 3 must be extended. While extensions most commonly appear in Wave 3, they can also occur in Wave 5 or Wave 1.

Illustration: Elliott Wave extensions in Waves 1, 3, and 5 (common scenarios).

Statistics show that 90% of extensions occur in Wave 3, making it the strongest wave. When Wave 3 extends, it typically reaches at least a 1.618 Fibonacci extension of Wave 1 and can extend up to 2.618 or beyond. Extensions in Wave 5 are more likely than in Wave 1.

Elliott Wave Extensions: Key Rules to Follow

– If wave 5 is extended – wave 3 needs to be longer than wave 1, otherwise Elliott Wave count is wrong.
– When wave 1 extends – wave 5 must be shorter than wave 3, otherwise Elliott Wave count is wrong.
– For an extended wave 3  – wave 5 target could be got in 2 ways. It could be eather equal in length to the wave 1 or it’s 61.8% fibonacci extension of the length wave 1+wave 3 related to the wave 4.
– Impulsive waves with at least 1 wave extended should at least contain 9 swings and would increase to 13 or 17 swings if there are more extensions within.
