This is a nice mental exercise for you guys.

Look at the left shoulders of both of those head and shoulders i just posted.

The price action inside both left shoulders is strikingly similar.

The price action inside both heads is strikingly similar.

The price action inside both right shoulders is strikingly similar.

Isn't that neat?

It's proof that head and shoulders have mini fractals inside the shoulders themselves that are observable and identifiable among other head and shoulders patterns.
