Elliott Wave Theory
Elliott Wave Theory interprets market actions in terms of recurrent price
structures obedient to the Fibonacci sequence. Basically, Market cycles are composed
of two major types of Wave : Impulse Wave and Corrective Wave. For every
impulse wave, it can be sub-divided into 5 - wave structure (1-2-3-4-5), while
for corrective wave, it can be sub-divided into 3 - wave structures
(a-b-c).

An important feature of Elliott Wave is that they are
fractal in nature. 'Fractal' means market structure are built from similar
patterns on a larger or smaller scales. Therefore, we can count the wave on a
long-term yearly market chart as well as short-term hourly market chart.
See waves within wave:
Based on the market pattern, we can identify ' where we are'
in term of wave count. Nevertheless, as the market pattern is relatively
simplistic, there are several rules for valid counts:
There are three major types of wave form in Impulse
Wave:
Among Wave 1, 3 and 5, only one should unfolded into
extended wave. 'Extension' means the wave is elongated in nature and sub-waves
are conspicuous in relation to waves of higher degree.
See extension pattern:
Sometimes, the momentum at Wave 5 is so weak that the 2nd
and 4th sub-waves overlap with each other and evolved into diagonal
triangle.
In some other circumstances, the Wave 5 is so weak than it
even cannot surpass the top of the wave 3, causing a double top at the end of
the trend.

Corrective Wave forms are rather complicated, but basically
we can categorize them into six major wave forms:
See Six Corrective patterns:

The attractiveness of Elliott Wave Analysis is : Three impulse wave forms and six corrective wave forms are conclusive. All we have to do is to identify which wave form is going to unfold in order to predict future market actions. This is a bold statement, needless to say, knowledge of market historical wave patterns and experiences in wave count are of paramount importance.
