When there are sgwiggly lines next to a chord do you go up or down the notes?

The wavy line next to a chord indicates that the chord should be played in an arpeggiated style. This means that the notes of the chord should be played one at a time, rather than all at once. The direction of the wavy line indicates whether the notes should be played ascending or descending. For example, an upward-sloping wavy line indicates that the notes should be played from low to high, while a downward-sloping wavy line indicates that the notes should be played from high to low.
