The basic mathematical characteristic of the log spiral is that while increasing or decreasing in size, its shape remains constant. This is also true for rectangular spirals, the parameters of which are determined by their related log spirals. Many major market moves share the properties and predetermined progression of these spirals, indicating the close correlation between multiple manifestations of ordered form in Nature and the architecture of markets themselves.
Three important turning points, between 1974 and 1978, have influenced the growth pattern of many subsequent major and minor market moves, up to and including the July 20, 1998 peak and the September and October, 1998, lows for the DJIA and S&P, respectively. Some of the many moves influenced by the 1974-78 activity will be examined in detail in this article. The triangle in Figure 1 connects the 1974 low, S&P, with the 1976 peak and 1978 low, at which points both the DJIA and S&P reversed on the same day. At the 1974 low the DJIA reversed 45 days later than the S&P. The triangle connects Points 1-3. The dotted points indicate those moves which are analyzed in this article.

This is termed a Compound Pivot, explained later in this article. |
THE CASE FOR ORDER
Before proceeding to the examples, it is helpful to review two schools of thought regarding the possibility of order in the markets and some properties of log spirals. Technical analysis has made amazing progress since the advent of computers, but this progress has not quieted the debate between random walk proponents and advocates of mathematically ordered markets. Random walk supporters cite the millions of subjective, individual decisions and unpredictable fundamental events as sufficient reasons for the impossibility of ordered markets. The philosophical argument for orderly markets is based on the following:
| Market moves are the result of the concurrent dominant psychological factors translated into market moving decisions by the aggregate of participants. The participants are human beings. |
| Humans are indisputably a part of Nature. |
| As a product of humankind, markets are as inherently natural as thousands of geometrically perfect honeycombed beehives produced by billions of bees. |
| From the atom, to living organisms at every level, to the farthest extent of the cosmos, Nature exhibits the ability to create order out of an infinite number of seemingly chaotic inputs. Order endures, unscathed by a perpetual barrage of potentially disruptive influences.Our work at Ermanometry Research provides the mathematical basis and evidence that the markets are merely a microcosm of the larger natural universe in which they exist. Markets, as children of Nature, naturally digest and convert their myriad inputs into orderly progressive patterns of growth, both in time and price. ERMANOMETRY, the book, details the case for order with examples from many other tools for decoding the predetermined paths of all markets, such as the Erman Wave, Golden Mean, asymmetrical analysis, and index interaction, in addition to projecting growth patterns. |

Figure 3: HALF SECTION VIEW OF A NAUTILUS SHELL. Successive increments of growth are united by a constant common ratio of expansion.
One of the most widely known examples of orderly progression in Nature is the nautilus. Figure 2 shows a half section view of this remarkable mollusk’s shell. As the animal’s growth forces the shell to increase in size, the shape of the shell never changes. The radius increases proportionately as the shell grows longer. Successive increments of growth are united by a constant, common ratio of expansion.

FIGURE 4: LOG SPIRAL OF THE NAUTILUS SHELL. A rectangular spiral, bounded by the Log Spiral, has been added.
Figure 4 approximates the spiral growth curve of the nautilus. Two perpendicular lines, similar to polar axes, have been drawn through the center of the spiral at point X. As the spiral curves around Point X it crosses the axes at a series of points labeled A through J. These points have been connected with a series of straight lines. Note that each line is perpendicular to the preceding and successive lines in the series. Therefore adjoining pairs of lines are the legs of successively larger right triangles, with segments of the axes forming the hypotenuse of each triangle. Example: Triangle EFG has legs EF and FG, and axis segment EG is the hypotenuse.
The axes segments have the same constant growth ratio as the spirals. Therefore the diagram could be turned "inside out" using the axes segments as the rectangular spiral. The values for the previous rectangular spiral segments would now become axes segments. The shape of the log spiral would remain constant.
CLASSICAL CYCLICAL ANALYSIS - ERMANOMETRY CONSIDERS MARKET TIME SPHERICAL
All markets exhibit orderly growth patterns in both time and price. Ermanometry considers time the dominant influence on market movements, and the examples herein will concentrate on time. There are always multiple growth patterns influencing the market at any given time. In classical cyclical analysis a forty week cycle might be moving up while a forty month cycle is moving down, and the analyst seeks to find the point in time when the majority of long and short term cycles are in sync; due to top or bottom together within a relatively short time span. The analysis of growth patterns is similar in that the analyst looks for that place in time where several growth patterns intersect. This is the only similarity between Ermanometry’s analysis of time and classical cyclical analysis. Classical analysis views market time as always moving forward, left to right on the chart, or plane. A new cycle, of any given length, is expected to begin where the previous cycle ends. Growth pattern analysis in Ermanometry perceives market time as spherical, and multidimensional. Growth segments are contiguous but the essence of their continuity is skewed when portrayed on the plane. Two contiguous segments may be separated by long periods of time on the plane. This phenomenon is similar to the difference in perspective that would arise if a flat map of the earth were wrapped around a globe. The obvious problem is that it would not "fit" and the resulting picture would bear little resemblance to a true picture of the earth. A spherical perspective requires that time be viewed as revolving, and analysis is done "clockwise" and "counterclockwise", so that those growth pattern segments that are not evident on the plane may be considered. As few as three segments may be used for proper analysis. This would equate to 270 degrees or three quarters of one complete revolution of the log spiral. Values for market moves may appear and reappear in different geometrical shapes. A straight line may appear as a circle or triangle, or as a series of non-contiguous straight lines.
| A Few Ermanometry Principles | ||||
The day count and determination of turning points for the market moves illustrated in this article are based on certain principles of Ermanometry. Following is a brief explanation of the pertinent principles:
The day when a specific market move, either up or down, reaches its extreme intraday high or low price. Closing prices are not considered.
Time is measured in increments as small as 15 minutes. The largest increment is a single trading day. Time is never measured in weeks or months. Ermanometry does not count days when the markets do not trade.
The S&P and DJIA are considered one "market" and are always analyzed in concert. A Compound Pivot occurs when the two indices record their extreme prices on different days. Currently, both made their high extremes on July 20, but their lows were made 26 trading days apart, September 1, and October 8. Each of these low days represents the lowest intraday price subsequent to the July 20 top. Therefore they are identified as two components of a Compound Pivot. The components are interchangeable and may be "mixed and matched": Time may be measured from a previous pivot to all components of a Compound Pivot. Therefore it is quite common to measure from a DJIA pivot to an S&P pivot, and vice versa. The properties of the DJIA and S&P pivots are shared by a third pivot, termed the Balance Point. A Balance Point is that day precisely in between the two index pivots. Therefore, the Balance Point for the 09/01 and 10/08 index pivots would be 13 days forward from the DJIA low, and 13 days back from the S&P low.
Ermanometry allows for a maximum error factor of two days. This margin holds regardless of the length of moves being analyzed, including moves of 20,000 days or more. |
IDENTIFYING THE SPIRALS
The starting point for uncovering spiral growth patterns is at major market pivots. "Major" is a relative term and its quantification depends upon the time frame being analyzed. Analysis of short term patterns, 15 minute bars, might require only that the search start at the beginning of the current minor trend. For macro analysis of long term trends it is necessary to begin as far back as available data permit. The examples herein will cover the current long term patterns, and the year 1974 is used as a starting point. After the great depression low in 1932, both the DJIA and S&P reached their then historical nominal price peaks in 1973. "Nominal" as opposed to constant dollar/inflation adjusted historic highs, which were reached by the DJIA in 1966, by the S&P in 1968. The lows in 1974 represent the lowest nominal prices reached after the 1973 peak and many analysts consider 1974 the true beginning of today’s macro bull market. The S&P and DJIA reached their extreme intraday lows 45 trading days apart, and therefore the 1974 bottom is a Compound Pivot: S&P, 10/04/74, DJIA 12/09/74. Both indices made important lows on both days, but though the DJIA made a lower low on 12/09, the S&P held above its 10/04 low. Since the S&P pivot came first, it is the logical starting point for identifying a macro log spiral.

FIGURE 5: SEED SEGMENTS VALUES PLACED ON SEGMENTS (DE) AND (EF) OF RECTANGULAR SPIRAL.
The first move of sufficient importance considered in identifying a macro log spiral is the advance from the S&P 1974 low to the 1976 top. On Figure 1 the heavy line connecting Points 1&2 shows this 497 day move. The second move considered is the decline from 1976 to 1978, Points 2&3, 362 days. The third move is from the 1974 low to the 1978 low, Points 1&3, 859 days. Ermanometry considers the time distance between any two important pivots as a separate and distinct move, even if it encompasses other important moves. Therefore, though the 859 days from low to low ( point 1&3) has already been considered as a 497 day advance and a 362 day decline, the 859 days is treated as a third move.
Only two moves, which will be termed "seed segments" when referring to log and rectangular spirals, can be used to initially identify growth patterns, because a constant ratio of growth must be established. The 497 and 362 day segments will be used for the first example:
| Step 1: Calculate the ratio between 497 and 362:
497 / 362 = 1.37293 The inverse of the ratio must also be calculated, so that the spiral may wind counter clockwise as well as clockwise: 1 / 1.37293 = .72836 A minimum of 3 segments, 270º/3 quadrants, should be used when rotating counter clockwise. Step 2. Place the seed segment values, 362 and 497, on segments DE and EF of the rectangular spiral. Using DE and EF allows for 3 segments counter clockwise. See Figure 4. Step 3: The value for the remaining segments of the rectangular spiral may be calculated using the constant growth/decay ratios derived in Step 1. EXAMPLE: |
Values For Rectangular Spiral Segments
AB = 139.88
BC = 192.05
CD = 263.67
DE = 362.00
EF = 497.00
FG = 682.35
GH = 936.81
HI =1286.17
IJ =1765.83
EXAMPLES
| PROJECTING THE 1982 LOW | ||
CD 263.67 DE 362.00 EF 497.00 Total 1122.67
Figure 6 illustrates how the sum of the 2 Seed Segments, DE & EF added to the segment 90º counterclockwise, CD, totals 1122.67 days. This is the number of days from point 3, the 1978 low, to the 1982 low. Three perpendicular lines, or 270º, become a single straight line which is the four year move. 1982, Point 7 is now a valid point from which to project forward with spiral segments. 1982 is a Compound Pivot with the indices reaching their extremes 3 days apart. |
| PROJECTING THE 1982 LOW | ||
CD 263.67 DE 362.00 EF 497.00 Total 1122.67
Figure 6 illustrates how the sum of the 2 Seed Segments, DE & EF added to the segment 90º counterclockwise, CD, totals 1122.67 days. This is the number of days from point 3, the 1978 low, to the 1982 low. Three perpendicular lines, or 270º, become a single straight line which is the four year move. 1982, Point 7 is now a valid point from which to project forward with spiral segments. 1982 is a Compound Pivot with the indices reaching their extremes 3 days apart. |
| PROJECTING THE 1984 LOW | ||
DE 362 EF 497 FG 682.35 GH 936.81 Total 2478.16
In figure 5, 3 perpendicular lines "straightened themselves out" to become an important move. In Figure 6, 4 perpendicular lines, one complete revolution of the spiral, equate to an important 10 year move. |

Please refer to the table of dates for the numbered points on the chart. Points 6 & 6A represent the peaks for the S&P in 1980, and the DJIA in 1981, 103 days apart. These points are the extreme highs for the respective indices after the 1980 low, and together they comprise a Compound Pivot. |

Remember that the basis for the spirals was the 1974 S&P low. 1147 is the time distance from the 1970 low to the 1974 DJIA low. If once again these segments are considered segments of the circumference of a circle, and we calculate the diameter: The 1102 represents the time distance from the 1970 low to the 1974 S&P low.

1484 days (segment GH) is the time distance from Point 2, 1976 peak and terminus of seed segment 497, to Point 7, the 08/09/82 low. Please note that this confirms the projection for the same day illustrated in Figure 8! |

BEYOND THE BASICS
The twenty examples shown thus far are merely the tip of the iceberg of future turbulence created by the market action of 1974-78. There is a great deal more to this iceberg that causes the titanic market to continually change course, at projected pivot days. Perhaps this is a lame analogy since the "iceberg" cannot sink the market! Additional exploration can be accomplished by calculating the square root of the growth ratio between 497 and 859. The growth ratio we have been using for these two seed segments is 1.72837, and the square root of the ratio is 1.31467, which we will now use as a growth ratio, to get deeper "inside" the spiral.
497 x 1.31467 = 653.3934 : 653.3934 x 1.31467 = 859
Only the original seed segments are placed on the spiral. (Note: The spiral diagram is NOT TO SCALE.) The axes segments can be calculated, as explained previously.

CONCLUDING COMMENTS
The markets may be appreciated for their harmonious and disciplined movements, and even as objects of beauty. However, that admiration will bring only esthetic rewards. A true belief in perfectly patterned markets should spur the reader to uncover even more evidence of order and to profit from it. It must be stressed that Ermanometry uses many other algorithms for pattern analysis, and not only do they have to confirm growth analysis projections, but spirals from different time frames must intersect at future pivot points to increase the potential of any specific date.
| ERRORS IN LOG SPIRAL ARTICLE | |||||
|---|---|---|---|---|---|
in the February, 1999 issue of Stocks & Commodities
The following corrections are required: No. Incorrect Date Correct Date 1. 10/10/74 10/04/74 2. 09/09/76 09/22/76 6. 11/24/80 11/26/80 8. 10/10/90 10/11/90 When any of these dates appeared in the text or figures, the correct date was used.
The correct total is 4028, not 1314.72 . This total is in the lower left hand corner, top half of figure.
For both of these figures the axes segments were incorrectly labeled and colored. The error is consistent: All segments used are listed and colored one/quarter turn too early. All should be rotated ninety degrees clockwise. For example: Figure 8, XE = 401.73, should read XF etc. XD = 292.6, should read XE etc.
The axis segment XG, value 757, was omitted from the column totaled in the lower left hand corner, top half of figure. However, since all segments should be rotated ninety degrees, the missing segment is actually XH. There were no computational errors of any sort, except for the faulty totals in figures 10 & 13. |
