What is On-Balance Volume?

On-Balance Volume is a cumulative volume indicator that adds or subtracts volume according to whether price closes higher or lower.

On-Balance Volume 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 On-Balance Volume

Read On-Balance Volume 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 On-Balance Volume 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.

BondStats interpretation rule

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.
