What is Advance Decline Line?
The advance-decline line is a cumulative breadth measure built from the difference between the number of advancing and declining securities.
Advance Decline Line matters because it gives analysts a consistent way to discuss cross-market and breadth analysis. Breadth and relative-strength measures shift attention from one price series to the behavior of a wider group or a comparison benchmark.
How to read Advance Decline Line
Read Advance Decline Line as a comparison rather than an absolute signal. The benchmark universe, weighting and lookback period determine what relative strength or breadth is actually measuring.
What Advance Decline Line does not tell you
The term should be read as descriptive chart language rather than as a self-contained forecast. Parameter choices, timeframe and data quality can materially change the result.
Use in bonds, rates and macro markets
This is especially relevant to global macro and fixed income, where cross-country yields, curves, currencies and risk assets often move through shared regimes.
Technical chart structures are context, not certainty. BondStats does not present a candlestick, drawing tool, indicator reading or chart pattern as a standalone investment recommendation. Where a concept depends on discretionary anchors or parameter choices, those choices should be made explicit.
