Accumulation/distribution
The Accumulation/Distribution is a momentum indicator that associates changes in price and volume. The indicator is based on the premise that the more volume that accompanies a price move, the more significant the price move. Accumulation/Distribution attempts to confirm changes in prices by comparing the volume associated with prices. When the Accumulation/Distribution moves up, it shows that the security is being accumulated, as most of the volume is associated with upward price movement. When the indicator moves down, it shows that the security is being distributed, as most of the volume is associated with downward price movement. Divergences between the Accumulation/Distribution and the security's price imply a change is imminent. When a divergence does occur, prices usually change to confirm the accumulation/distribution. For example, if the indicator is moving up and the security's price is going down, prices will probably reverse. If the days price change is positive then the difference in the daily high and low price is added to the total, and conversely if the daily change is negative then the daily range is subtracted from the total.
