Wolf Wave is a price action pattern that is made up of 5 waves which show supply and demand relation in terms of  pricing movements which fights towards an equilibrium price.

Bullish wolf wave normally forms in falling channels and bearish in rising channels.

And to be considered a wolf wave, the following rules must be obeyed:

1. Waves 3-4 must stay within the channel created by 1-2
2. Wave 1-2 equals waves 3-4 (shows symmetry)
3. Wave 4 is within the channel created by waves 1-2
4. There is regular time between all waves
5. Wave 5 exceeds trend line created by waves 1 and 3 and is the entry point.
