Volume Advance Decline

The Volume Advance Decline (VAD) calculates a ratio based on the range of the bar and the relationship of the close to the open. This ratio is then multiplied by the volume and added (or subtracted) from the last VAD value. If for a given day, the Close was 20c higher than the Open, and the Range of the Day (High to Low) was $1, then the day’s volume would be multiplied by 0.2 and added to the previous value.
