The harmonic approach to trading the markets is a cyclical one. Our tools for evaluating market position and trend are pattern recognition, momentum analysis, Elliot Wave Theory and dynamic price and time analysis. While some technicians will attempt to force wave counts on every market at every time, such an approach is neither practical nor profitable. 

    A working knowledge of Elliott wave theory is very useful for several reasons:

  • Wave theory provides a useful way to “frame out a market”. This structure provides order amidst chaos.
  • Wave theory gives you the tools to project extended price targets and capture potentially large moves that you might otherwise miss.
  • Wave theory can help you make better trade management decisions and reduce risk.

Elliott 5 Wave pattern

The 5 wave pattern comes directly from the work of R.N. Elliott and was re-introduced to the trading community in 1978 in the book Elliott Wave Principle – Key to Market Behavior by A.J. Frost and Robert R. Prechter. The basic assumption is that following the completion of the 5th wave the market will retrace at least 50% of the entire move. The 5th and final wave can unfold in several different ways (typical 5th wave, truncated or failed 5th wave, diagonal 5th wave). Here are two examples:

ABC Correction

The abc correction (also referred to as an ab=cd) is by far the most common trading pattern we see in this method. These form in all markets and on a daily basis. They can be very effective ways to jump on a trend. The challenge with this pattern comes in correctly identifying trend and realizing when your abc is morphing into something else like a complex correction or an impulse wave.

Elliott Wave Principle
by Howard Arrington

R.N. Elliott studied price movement in the markets and observed patterns that repeat themselves.  He used this discovery to make accurate forecasts in the stock market.  To the untrained eye, market movement may appear random and unrelated.  In reality, the markets are tracing out patterns that you can learn to recognize and profit from.   Mr. Elliott named this discovery the ‘Wave Principle’, but died before his work became well known.  In the late 1970’s Robert Prechter and A.J. Frost brought Elliott’s work out of obscurity in their book ‘Elliott Wave Principle‘.  This article offers a few basics in understanding the Wave Principle.

Society behavior trends and reverses in recognizable patterns.  This principle is found in market behavior because investors act and react to transaction information.  The behavior forms repetitive patterns, and because the patterns are repetitive, they have predictive value.  Elliott identified thirteen patterns that recur in the markets.  He then assembled these patterns or waves into larger versions of the same patterns.  These became building blocks to patterns of the next larger size.

The most basic pattern is a structure consisting of 5 waves.  Three of the five waves are directional and referred to as Trend waves.  These trend waves are separated by two interruptions that are counter trend and referred to as Retracement waves.  Using T for a Trend wave, and R for a Retracement wave, the pattern can be described as T-R-T-R-T.  The classic pattern is shown in this theoretical chart.

The three Trend waves are labeled 1, 3, and 5.  The two Retracement waves are labeled 2 and 4.  Each Trend wave has a 5 sub-wave structure and each Retracement wave has a 3 sub-wave structure.  In the illustration the larger degree wave is labeled with the large red numbers.   The Trend waves to labels 1, 3, 5consist of  5 sub-waves labeled with the small blue numbers 1-2-3-4-5.  The 3 sub-waves in Retracement waves to labels 2 and 4 are labeled with small blue letters a-b-c.  Keep in mind that each wave is just a member of a larger structure, and conversely each wave can be subdivided into waves of a lesser degree.

Basic Elliott Wave Principles:

  • Trend waves subdivide into 5 waves.
  • Retracement waves subdivide into 3 waves.
  • Wave 2 never retraces more than 100% of wave 1.
  • Wave 4 never retraces more than 100% of wave 3.
  • Wave 3 always exceeds the price level of wave 1.
  • Wave 3 is often the longest and never the shortest of waves 1, 3, and 5.
  • When wave 5 does not exceed the price level of wave 3, it is called a Bull or Bear Market Failure, and gives warning of underlying weakness or strength in the market.  The 5th wave was cut short or truncated because of the underlying weakness or strength.
  • A Trend wave may form a diagonal triangle pattern, or wedge shape, still containing 5 sub-waves.
  • A Retracement wave may form a horizontal triangle pattern, and these may have 5 or more sub-waves.
  • If wave 2 is a sharp retracement, then expect wave 4 to be a sideways correction, and vice versa.
  • Lines drawn to form a parallel trend channel often mark the upper and lower boundaries of the waves.  Drawing a trend line using points 1 and 3 may forecast the end of wave 5 when waves 1 and 3 are normal.
  • The Wave Principle does not provide certainty about any market outcome.  But, it can be a means to assess possible future market action.

Fairly often, a retracement wave retraces a Fibonacci percentage of the preceding wave.  Sharp corrections often retrace 61.8% or 50%.  Sideways corrections often retrace 38.2%, particularly in wave 4.  Most analysts focus on Retracement waves and measuring wave heights to forecast a price objective using Fibonacci ratios.  Tip: Use Fibonacci principles to forecast a price, and use Elliott principles to determine when a wave is mature or finished.  Look for correlation of the two.

There will be times when market analysis is confusing and the interpretation is unclear.   My advice is to leave confusing patterns alone until subsequent waves clarify the picture.  The best approach is to apply deductive reasoning.  Learn Elliott Wave Principles, rules and patterns, and use this knowledge to deduce what will be the likely course for the market.  A primary purpose of the analysis is the determination of whether a pattern is complete, whether a wave is finished.  If the market changes direction as expected, you caught the turn.  If the market misbehaves, your conclusion is wrong and money at risk should be immediately reclaimed.  Tip: Be patient and understand first where the market is at in the unfolding pattern, and then trade with the trend.

Harmonic Numbers

Harmonic numbers are the “Davinci Code” of most liquid financial markets. The numbers are derived from the Fibonacci summation series which starts with 0 and adds 1. Each succeeding number in the series that are by the fort collins adds the previous two numbers thus we have 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 to infinity. If you divide 55 by 89 you have the golden mean – .618. If you divide 89 by 55 you have 1.618.


  • .382 is the difference of 1.00 – .618 = .382
  • .618 is the golden mean (phi) and the square root of .382 
  • .786 is the square root of .618 
  • 1.27 is the square root of 1.618 – it is also the hypotenuse of a right triangle 
  • 1.618 is difference of the square root of 4 minus .382 (2 – .382 = 1.618)
