Basics of Wave Analysis
The Elliott waves principle is a system of empirically derived rules for interpreting action in the markets. Elliott pointed out that the market unfolds according to a basic rhythm or pattern of five waves in the direction of the trend at one larger scale and three waves against that trend. In a rising market, this five wave/three-wave pattern forms one complete bull market/bear market cycle of eight waves. The five-wave upward movement as a whole is referred to as an impulse wave, and the three-wave countertrend movement is described as a corrective wave (See Figure 6.1). Within the five-wave bull move, waves 1, 3 and 5 are themselves impulse waves, subdividing into five waves of smaller scale; while waves 2 and 4 arecorrective waves, subdividing into three smaller waves each. As shown in Figure 6.1, subwaves of impulse sequences are labeled with numbers, while subwaves of corrections are labeled with letters.

As the illustration shows, waves of any degree in any series can be subdivided and resubdivided into waves of smaller degree or expanded into waves of larger degree.

1. A second wave may never retrace more than 100 percent of a first wave; for example, in a bull market, the low of the second wave may not go below the beginning of the first wave.
2. The third wave is never the shortest wave in an impulse sequence; often, it is the longest.
3. A fourth wave can never enter the price range of a first wave, except in one specific type of wave pattern, the form of market movements is essentially the same, irrespective of the size or duration of the movements.

In any given five-wave sequence, a tendency exists for one of the three impulse subwaves (i.e., wave 1, wave 3, or wave 5) to be an extension—an elongated movement, usually with internal subdivisions. At times, these subdivisions are of nearly the same amplitude and duration as the larger degree waves of the main impulse sequence, giving a total count of nine waves of similar size rather than the normal count of five for the main sequence. In a nine-wave sequence, it is sometimes difficult to identify which wave is extended. However, this is usually irrelevant, because a count of nine and a count of five have the same technical significance. Figure 6.4. shows why this is so; examples of extensions in various wave positions make it clear that the overall significance is the same in each case. Extensions can also occur within extensions. Although extended fifth waves are not uncommon, extensions of extensions occur most often within third waves, as shown in

The Diagonal Triangles
There are some patterns familiar from the Technical Analysis theory, particularly two types of triangles, which should be noticed in frame of Elliotts waves consideration.
The diagonal triangle type 1 occurs only in fifth waves and in С waves, and it signals that the preceding move has, in accordance to Elliott, "gone too far, too fast." All of the patterns' sub-waves, including waves 1, 3, and 5,consist of three-wave movements, and their fourth waves often enter the price range of their first waves, as shown in Figures 6.6. and 6.7. A rising diagonal triangle type 1 is bearish, because it is usually followed by a sharp decline, at least to the level where the formation began. In contrast, a falling diagonal type 1 is bullish, because an upward thrust usually follows.

Elliott described as a failure an impulse pattern in which the extreme of the fifth wave fails to exceed the extreme of the third wave. Figures 6.9 and 6.10 show examples of failures in bull and bear markets. As the illustrations show, the truncated fifth wave contains the necessary impulsive (i.e., fivewave) substructure to complete the larger movement. However, its failure to surpass the previous impulse wave's extreme signals weakness in the underlying trend, and a sharp reversal usually follows.
