There are four different variations of a 5 wave move:
1- Impulse wave,
2- Impulse with Extension
3- Impulse with Truncation
4- Diagonal.
Five wave structures :
1- Impulse:
1-1 Extensions : Appears in either wave 1, 3 or 5.
1-2 Truncations : wave 5 does not exceed the end of wave 3. often occurs after a strong third wave.
2- Diagonal triangles:
Leading Diagonal, Ending Diagonal
Wave 4 almost always moves into the price territory of wave 1.
Normally has wedge shape
