What is Negative Volume Index?
Negative Volume Index is a volume, flow or participation measure used to add transaction-activity context to a price chart. It can help distinguish a move supported by broader activity from one occurring on relatively limited participation.
Negative Volume Index matters because it gives analysts a consistent way to discuss volume and participation analysis. Volume-based tools add information about participation and transaction activity that price alone cannot show.
How to read Negative Volume Index
Read Negative Volume Index with an understanding of what the volume dataset includes. Exchange-traded volume, consolidated equity volume, futures volume and fragmented dealer-market activity are not interchangeable.
What Negative Volume Index does not tell you
Its reading depends on the quality and coverage of the underlying volume data, which can differ substantially across markets and venues. Parameter choices, timeframe and data quality can materially change the result.
Use in bonds, rates and macro markets
Cash-bond markets are fragmented, so volume measures may represent only a venue or instrument; futures and exchange-traded products often provide cleaner chartable volume. In fragmented OTC bonds, always identify whether the chart uses dealer quotes, reported trades, futures or an exchange-traded proxy.
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.
