The Chaikin Accumulation/Distribution (A/D) Line measures the relationship between price movement and trading volume. It helps determine whether a symbol is experiencing accumulation (buying pressure) or distribution (selling pressure).

For automated trading strategies, the Chaikin A/D Line helps confirm whether price movement is supported by volume, which can indicate the strength or weakness of a trend.

What does the Chaikin A/D Line measure?

The Chaikin A/D Line combines price position within the trading range and trading volume to estimate whether buyers or sellers are dominating the market.

The indicator increases when:

• Price closes near the higher end of its range and
• Trading volume is strong

The indicator decreases when:

• Price closes near the lower end of its range and
• Trading volume increases during selling pressure

In general:

• A rising A/D Line suggests accumulation (buyers are dominant)
• A falling A/D Line suggests distribution (sellers are dominant)

This helps traders understand whether volume supports the current price movement.

How the Chaikin A/D Line is used in indicator-based triggers

In automation, the Chaikin A/D Line can be used to detect whether buying or selling pressure is increasing.

For example, strategies may monitor when:

• The A/D Line crosses above a defined value, suggesting stronger accumulation
• The A/D Line moves relative to another indicator, confirming whether volume supports the current price trend

These types of triggers allow automated strategies to react when volume begins to confirm price direction.
