Motive waves, also known as impulse waves, are a type of price movement pattern observed in financial markets, particularly in Elliott Wave Theory. They are characterized by five waves in the direction of the trend, labeled 1, 2, 3, 4, and 5, with three upward waves (1, 3, and 5) and two corrective waves (2 and 4).
MOTIVE WAVES
Motive waves subdivide into five waves and always
move in the same direction as the trend of one larger degree. They are
straightforward and relatively easy to recognize and interpret.
Within motive waves, wave 2 always retraces less
than 100% of wave 1, and wave 4 always retraces less than 100% of wave 3. Wave
3, moreover, always travels beyond the end of wave 1. The goal of a motive wave
is to make progress, and these rules of formation assure that it will.
Elliott further discovered that in price terms, wave
3 is often the longest and never the shortest among the three actionary waves
(1, 3 and 5) of a motive wave. As long as wave 3 undergoes a greater percentage
movement than either wave 1 or 5, this rule is satisfied. It almost always
holds on an arithmetic basis as well. There are two types of motive waves:
impulse and diagonal triangle.
The most common motive wave is an impulse. In an
impulse, wave 4 does not enter the territory of (i.e., “overlap”) wave 1. This rule
holds for all non-leveraged “cash” markets. Futures markets, with their
extreme leverage, can induce short term price extremes that would not occur in
cash markets. Even so, overlapping is usually confined to daily and intraday
price fluctuations and even then is rare. In addition, the actionary subwaves
(1, 3 and 5) of an impulse are themselves motive, and subwave 3 is specifically
an impulse. Figures 2, 3 and 4 depict impulses in the 1, 3, 5, A and C
wave positions.
As detailed in the preceding three paragraphs, there
are only a few simple rules for interpreting impulses properly. A rule is so
called because it governs all waves to which it applies. Typical, yet not
inevitable, characteristics of waves are called guidelines. Guidelines of
impulse formation, including extension, truncation, alternation,
equality, channeling, personality and ratio
relationships are discussed below. A rule should never be disregarded. In many
years of practice with countless patterns, we have found but one instance above
Subminuette degree when all other rules and guidelines combined to suggest that
a rule was broken. Analysts who routinely break any of the rules detailed in
this section are practicing some form of analysis other than that guided by the
Wave Principle. These rules have great practical utility in correct counting,
which we will explore further in discussing extensions.
Extension
Most impulses contain what Elliott called an extension.
Extensions are elongated impulses with exaggerated subdivisions. The vast
majority of impulse waves do contain an extension in one and only one of their
three motive subwaves (1, 3 or 5). The diagrams in Figure 4, illustrating
extensions, will clarify this point.
Often the third wave of an extended third wave is an
extension, producing a profile such as shown in Figure 5.
Truncation
Elliott used the word “failure” to
describe a situation in which the fifth wave does not move beyond the end of
the third. We prefer the less connotative term, “truncation,” or “truncated fifth.”
A truncation can usually be verified by noting that the presumed fifth wave
contains the necessary five subwaves, as illustrated in Figures 6 and 7. Truncation often
occurs following a particularly strong third wave.
Truncation gives warning of underlying weakness or
strength in the market. In application, a truncated fifth wave will often cut
short an expected target. This annoyance is counterbalanced by its clear
implications for persistence in the new direction of trend.
A diagonal triangle is a special type of wave that
occurs primarily in the fifth wave position at times when the preceding move
has gone “too far too fast,” as Elliott put it. A diagonal
triangle is a motive pattern, yet not an impulse, as it has one or two
corrective characteristics. Diagonal triangles substitute for impulses at
specific locations in the wave structure. They are the only five-wave
structures in the direction of the main trend within which wave four almost
always moves into the price territory of (i.e., overlaps) wave one. (See Figure 8.)
