Pull & Stack
Passive liquidity flow
Delta for the passive side: what gets added and what gets pulled.

What it is for
Measures how much size is being added to the book and how much pulled, by side and weighted by distance to price. Where delta counts aggressive volume, this counts added minus pulled. Unlike Spoof and Liquidity Stability, which only look at size worth suspecting, this watches the whole book: stacking liquidity is normal and informative.
Mode
Heuristic · MBO-ready
Aggregated depth checked against printed volume, which is what separates filled from cancelled.
Requirements
- Bookmap with live data
- Futures (ES/MES) or crypto
- miggy-pull-stack.jar
What it measures
- Net liquidity flow, signed
- Typical reference level
- Added and pulled per side
- Levels involved
How to read it
- The sign
- Positive means the book is building; negative, emptying. It reads as “thinner above” or “thinner below”, which is the useful question.
- Filled is not cancelled
- A shrinking level means two opposite things, and in aggregated depth they look identical. Every decrease is checked against volume actually printed, and only the unexplained remainder counts as a pull.
What it does NOT mean
It accuses nobody: stacking liquidity is what most of the book does, and pulling it as price approaches is normal too. For “this wall is fake” there is Spoof.
