Elliott Wave Theory is interpreted as :
Every action is followed by a reaction.
Five waves move in the direction of the main trend followed by three corrective waves (a 5-3 move).
A 5-3 move completes a cycle.
This 5-3 move then becomes two subdivisions of the next higher 5-3 wave.
The underlying 5-3 pattern remains constant, though the time span of each may vary.
Let's have a look at the following chart made up of eight waves (five up and three down) labeled 1, 2, 3, 4, 5, A, B and C.
You can see that the three waves in the direction of the trend are impulses, so these waves also have five waves within them. The waves against the trend are corrections and are composed of three waves.
