How Does Accumulation Distribution Work? An Expert Explains

Last Updated:

This page covers what accumulation distribution is, what the indicator shows, and how traders can use the accumulation distribution line in trading.

We include a detailed guide on interpreting the volumes presented by the accumulation distribution line, as well as a list of regulated brokers that offer demo accounts to practice the technique.

What Is Accumulation Distribution?

Accumulation Distribution uses volume to confirm price trends or warn of weak movements that could result in a price reversal.

  • Accumulation: Volume is considered to be accumulated when the day’s close is higher than the previous day’s closing price. Thus the term “accumulation day”
  • Distribution: Volume is distributed when the day’s close is lower than the previous day’s closing price. Many traders use the term “distribution day”

Therefore, when a day is an accumulation day, the day’s volume is added to the previous day’s Accumulation Distribution Line.

The Distribution Line

Similarly, when a day is a distribution day, the day’s volume is subtracted from the previous day’s Accumulation Distribution Line.

This is an example of the Accumulation Distribution Line in a Nasdaq 100 exchange-traded fund chart.

The main use of the Accumulation Distribution Line is to detect divergences between the price movement and volume movement.

Volume Interpretation

The suggested interpretation of volume goes as follows:

  • Increasing and decreasing prices are confirmed by the increasing volume.
  • Increasing and decreasing prices are not confirmed and warn of future trouble when the volume is decreasing.

High #1 to High #2

The Nasdaq 100 made an equal high (i.e. Double Top formation) at High #2; however, the Accumulation Distribution Line failed to make an equal high, in fact, it made a lower high.

On average, less volume was transacted on the move higher at High #2 than occurred on the first move higher at High #1; thus, this could be interpreted as there being less strength and conviction behind the rally in the Nasdaq the second move higher.

This failure of the Accumulation Distribution Line signaled a strong bearish divergence.

High #3 to High #4

Again, the Accumulation Distribution line made a lower high, even though the Nasdaq 100 this time made a higher high.

This bearish divergence warned that the second move to make a higher high in price lacked conviction.

Low #1 to Low #2

The bearish divergence from Low #1 to Low #2 confirmed the later bearish divergence of High #3 to High #4.

On average, more volume was occurring on down days than up days, even while the Nasdaq 100 was making higher highs and higher lows, which usually is considered a sign of strength.

In summary, the Accumulation Distribution Line is a very effective tool to confirm price action and show warnings of potential price reversals.

Other Useful Indicators

It is important to incorporate volume into price analysis, and the Accumulation Distribution Line is one of many indicators to do just this.

Other indicators that include price and volume analysis and could be considered more accurate than the Accumulation Distribution Line include:
