Advance-Decline Line

The Advance-Decline Line is a technical indicator used to measure the breadth of a market by calculating the difference between the number of advancing and declining assets over a specific period. In the context of cryptocurrency, this tracks the number of tokens that closed higher versus those that closed lower compared to the previous session.

By adding this net difference to a running total, traders can visualize the underlying market momentum regardless of the major index or market cap movements. A rising line indicates broad market participation in an uptrend, while a falling line suggests that fewer assets are supporting the price action.

This tool is essential for identifying potential reversals or confirming the strength of a trend in digital asset markets. It helps distinguish between a rally driven by the entire market and one driven only by a few high-cap tokens.

Understanding this breadth is crucial for assessing overall health and liquidity distribution within the crypto ecosystem.
