• The Accumulation/Distribution Line (A/D) measures the supply and demand of an asset or security by looking at where price closed in a period range and then multiplying that by volume.

  • The A/D indicator is cumulative, that is, the value of one period is added to or subtracted from the last one.
  • Generally, an uptrend A/D helps confirm an uptrend and a downtrend A/D helps confirm a downtrend.
