Pulling & Stacking Indicator
The Pulling & Stacking Indicator decomposes raw order flow (every resting order stacked or pulled, every aggressive execution) into one normalized signal, updated on every market event. It runs on Bookmap and NinjaTrader 8, and a user on either platform watching the same tape sees the same numbers (release-tested, not aspirational).
Total Flow = Passive Flow + Aggressive Flow, exactly, on every event.

Deep-book warningTop of book fighting the deep book, an adverse-risk caution, not an entry arrow.
Absorption & initiativeBook-vs-tape state, labeled as context only.
NoteThe indicator reflects the raw data stream: never filtered, never smoothed, never repainted. When it doesn’t have a trustworthy answer, it says so instead of plotting plausible-looking garbage.
