Advance Decline Index (ADI)

ADI accumulates each day's (advances − declines) into a single line — the market's cumulative participation. Rising ADI means most assets are winning most days, regardless of what the total market cap says.

Watch for divergence against price: total market cap making new highs while ADI trends down means the average coin is already in decline — distribution hiding behind a strong index. Convergent new highs in both are the confirmation signal.
