The Black wave loop is moving up and down indicating that the
phase is changing from positive to negative. The cosine of the
phase angle indicates the direction of current flow. How can
you say it has no direction? And only a blind person would assert
that the current loop is standing still while moving up and down.
Current that stands still is zero current.

A jump rope is a standing wave. Do you also assert that a jump
rope in motion is standing still?
