Descriptive, not a guaranteed forecast

What is Bid Ask Delta?

Bid Ask Delta 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.

Bid Ask Delta 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 Bid Ask Delta

Read Bid Ask Delta 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 Bid Ask Delta 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

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.

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.
