Corrective Waves

Corrective Waves are much harder to identify than impulse or motive waves and are much harder to label in real time. There is one important rule for corrections: they never form five waves. Only impulse waves form a five wave pattern. However, one or more of the subordinate waves of a corrective wave can consist of a five wave pattern, though this is not a rule as we will soon see when discussing the different types of corrections.

Guidelines for Corrective Waves

There are two guidelines that apply to corrective waves:

Alteration

The first is the guideline of alternation that states: if Wave 2 is a sharp correction, Wave 4 is likely to be a protracted, sideways correction; and if Wave 2 is a protracted, sideways correction, Wave 4 is likely to be sharp. More often than not, Wave 2 is a sharp correction and Wave 4 is a sideways correction.

Wquality

The second is the guideline of equality that states: Wave A and Wave C tend to be more or less equal in length. This guideline can be used to determine where Wave C is likely to end.

Types of Corrections

There are a total of four basic wave patterns for corrections: zigzag corrections, flat corrections, triangles, and combination corrections.

Zigzag Corrections

A Zigzag Correction

Zigzag corrections consist of a three wave pattern that is labeled A-B-C. The subordinate waves of a lesser degree that make up a zigzag correction form a 5-3-5 wave count. In these corrections, waves A and C are impulse waves and Wave B is a corrective wave of a lesser degree. A zigzag correction can extend to form double zigzags or triple zigzags with each zigzag being separated by an intervening wave that has three subordinate waves and is labeled X. You can often anticipate a double zigzag when Wave C of a zigzag appears to fall short of its normal target, though this is not a hard rule.

Flat Corrections

A Flat Correction

Flat corrections also consist of a three wave pattern that is labeled A-B-C but its subordinate waves form a 3-3-5 wave count. A characteristic of these corrections is that they are weak corrections with its Wave C often failing to exceed the length of Wave A. Flat corrections often follow a strong impulse wave and occur more often as the fourth rather than as a second wave of an impulse wave. Flat corrections have three subcategories: regular flat corrections; expanded flat corrections and running flat corrections.

Regular Flat Corrections

In a regular flat correction Wave B tends to be a 100% retracement of Wave A and Wave C tends to be slightly more than a 100% retracement of Wave B, ending slightly further than Wave A.

Expanded Flat Corrections

Expanded flat corrections have a megaphone shape with Wave B moving beyond the start of Wave A and Wave C moving beyond the start of Wave B.

Running Flat Corrections

Running flat corrections are very rare and are similar to expanded flat corrections with the exception that Wave C fails to move beyond the start of Wave B and also fails reach that end of Wave A.

Triangle Corrections

A Triangle Correction

Triangle corrections consist of five waves labeled A-B-C-D-E with the subordinate waves forming a 3-3-3-3-3 wave pattern. They reflect a momentary balance of forces between bulls and bears. In an ideal triangle correction, each successive wave will fall short of a 100% retracement of the previous wave. However, it is not uncommon to have wave B exceed the start of Wave A. Sometimes an expanded triangle is formed when each successive wave is more than a 100% retracement of the previous wave. The triangle is formed by connecting the end point of waves A and C and the ends points of waves B and D. Triangles always occur as the fourth wave of an impulse wave and is usually followed by a short, swift fifth wave that travels the approximate distance of the widest part of the triangle.

Combination Corrections

Zigzag, an Intervening Three, and a Flat

Combination corrections are usually horizontal corrections that form combinations of simpler three wave corrections, such as zigzag corrections, flat corrections and triangle corrections. However, a combination correction can end in a triangle correction but it cannot start with one. Each of hte simpler corrective patterns that make up a combination correction is separated by an intervening wave that has three subordinate waves as these are corrections in a correction. Combination corrections occur more often in the fourth wave.



The 3 Rules of Elliott Waves

There are only three simple rules in Elliott Wave Theory that apply to impulse waves and should never be broken. The rules are:

  1. Wave 2 may not retrace beyond the start of Wave 1. If it does, then it is part of a corrective phase.
  2. Wave 3 cannot be the shortest of the three motive waves, namely waves 1, 3 and 5. It does not need to be the longest of the three, but it cannot be the shortest.
  3. Wave 4 must not penetrate and overlap the price action of wave 1, except in the case of a diagonal triangle.

In addition to these three rules are a few guidelines that are typical of Elliott waves but do not occur in every 5-3 wave cycle. These guidelines include the extension of impulse waves, truncation of the fifth wave, alteration of the shape and length of the corrections at waves 2 and 4, and channeling of the motive wave.


Elliott Waves and Price Projections

There are a number of price projections that can be based on Elliott Wave Theory. The common price projections are as follows:

  • Wave 2 is usually a deep retracement of Wave 1 and usually ends at the 61.8% or 78.6% Fibonacci retracement levels. However, it cannot retrace beyond the start of Wave 1 as it would then still be part of a correction.
  • Wave 4 tends to end in the region of Wave 4 one lesser degree, i.e., in the region of subwave 4 of Wave 3. However, Wave 4 is also usually a protracted sideways correction, especially when Wave 2 was a sharp correction.
  • The guideline of equality states that Wave A and Wave C tend travel the same approximate distance. This guideline can be used to determine the possible end of Wave C, based on the length of Wave A.

Fibonacci Retracements

Fibonacci Retracements is a popular support and resistance indicator based on the proportional relationship between the numbers in the Fibonacci sequence. The Fibonacci sequence is the sum of the two numbers beginning with 0 and 1. The key ratios between these numbers are: 161.8%, 61.8%, 38.2% and 23.6%. These ratios, and the 50% ratio, are used to divide a price movement in a wave, and plot horizontal lines to determine where a retracement could find support or resistance before the trend resumes.

Trend lines play an important role in identifying chart patterns as they draw the chartist's attention significant price levels. Trend lines are relatively easy to draw. In an uptrend, which is characterized by higher highs and lower lows, a support trend line is drawn below two or more correction lows. If the trend line connects only two correction lows, it is a tentative trend line and is only confirmed when the price touches the line for a third time without breaking that line.
