The concept of the "price pulse" was developed by Tony Plummer in the 1980's while working at Hambros Bank and detailed in his book Forecasting Financial Markets . It is related to Elliott wave analysis and, indeed, might be seen as a less mechanical and more organic view of the same patterns Elliott studied. Plummer has said that nothing in the price pulse system contradicts Elliott wave analysis. The simpler components of his system can be used to construct the traditional Elliott patterns. The difference is that while Elliott patterns follow each other in a strict hierarchical and successive fashion (so that each primary five wave pattern is followed by a three wave retracement), the simpler price pulse of Plummer (three waves up) and its subsequent retracement (three waves down) can occur at different levels, overlaying and, in a sense, interfering with each other. So in a sense, Plummer's simpler structure shows the inner dynamics of Elliott's structure, the overlapping price pulse waves of higher degree interfering with lesser degree patterns to create the pattern Elliott saw .
Most traders using Fibonacci analysis use ratios less that one, primarily 0.618 and 0.382, to predict the extent of corrective waves. The price pulse begins with 1.618 (the primary Fibonacci ratio--the golden ratio or phi) and then computes powers of this number to predict targets for impulsive waves. This is related but in an important way different from what is often called Fibonacci "extensions." The difference is what is used as the "base" which is multiplied by the powers of phi. Plummer understood that it was not the original move up which should be computed as the base, but the subsequent corrective move, which he termed beta. The initial move up he referred to as the alpha wave. From the end of the beta move would come an impulsive delta wave, which should be targeted as some power of 1.618 times the distance of the beta wave.

Between 2005 and March of 2008 a very striking example of a long term alpha-beta-delta price pulse pattern unfolded in the spot Gold market. The extent of the impulsive or delta move corresponded to the theoretical targets to an astonishing degree.
From the summer of 2005 until May of 2006 spot gold had risen from the low 400's to a level around 730. This should be seen as the alpha wave. Subsequent there was sharp sell off back down to the 540 level. This was the beta wave. Using this initial pattern, once, in September of 2007, the price level rose above the initial alpha high, one could use powers of 1.618 to project delta target. Rising from the beta low, 1.618 times the distance between alpha and beta would be approximately 845.00. 2.618 times that distance would be approximately 1032.00.
As it happened, both targets came into play.

On November 7, 2007 spot gold peaked at 845.30, the exact 1.618 target. It came within ten cents of this level the next day but could not break through the 1.618 target level. By November 20, 2007 it had fallen by seventy dollars, the first serious correction since the impulsive move had gathered steam in August of that year. But then on the first trading day of 2008 it broke through that level. The implication was that it would now seek out the next price pulse target at 2.618 times the length of the base. That would theoretically be at 1032.40. On a Sunday evening in March of 2008, as the Asian markets opened, the spot gold market hit a high slightly above 1032.00 dollars. This was the weekend of the Bear Sterns debacle, when the Fed engineered the take over of the firm by JP Morgan Chase. It was a moment of absolute panic and it appeared to many that there was only one direction for the gold market, and that was to continue up to the sky. Instead there followed a seven month bear market in gold, which saw the price drop to a low around 680.00 in October. The gold market would not break through that March 2008 high until October of 2009.
Plummer has noted that often the end of a delta wave can become an alpha wave of the next move up. Assuming that March 2008 high was a new alpha and the October 2009 low was the end of the subsequent beta wave we can project the following pattern using a monthly chart.

The high on May 14 this year was ten cents above the theoretical 1.618 target. There followed a retracement of over eighty dollar.
But just as the previous retracement which occurred at this 1.618 level was followed, after a short and not very deep correction by a move up to the 2.618 target, we might logically expect the same to happen here. If this were to happen we would get a target of approximately 1600 dollars for the next move up.
