A sine wave has a fixed amplitude (price range) and frequency (time range). If we plot the pendulum swing against time we get a sine wave.
The markets look nothing like this, so how can we make sense of where prices are expected to move? Essentially the starting point is understanding that when different sine waves (amplitude and time) collide the resultant wave pattern that will be formed looks like neither – it is the sum of their respective amplitudes at the time of collision.
If you think of each fractal wave scale as a sine wave we are trying to trace the resultant path where the pitch forks (cycle forks) upper and lower parallels give the amplitude and the median line is where prices will always pass through.
