From the same chapter
- AbsorptionMassive aggression against passive liquidity that does NOT move price. Strong delta with price standing still means someone big is on the other side.
- IcebergAn order that reloads at the same price every time it gets eaten: invisible absorption in the book.
- SpoofingA large, visible wall that is PULLED before it is touched. Fake liquidity: never fade a wall because of its size.
- Stacking / PullingAdding liquidity at a level (stacking → usually real) or pulling it as price approaches (pulling → fake).
- Trapped tradersThose who entered a breakout that got absorbed. Their stops are the fuel for the move the other way.
