A/D Line (Daily)

The Noncumulative (Daily) Advance/Decline Line is calculated by subtracting the number of declining issues from the number of advancing issues and then dividing that figure by the total number of issues traded.

A/D Line = (Advancing Issues - Declining Issues) / (Total Number of Issues Traded)

Generally, values above 0.25 are considered "bullish" while values below -0.25 are considered "bearish."
