CVD — Cumulative Volume Delta#

In the Antigravity cosmology: Fuel / Energy Flow. In classical language: the cumulative difference between aggressively bought and aggressively sold volume.

What CVD really is#

Every market transaction has two sides, but only one of them is the aggressor: someone crossed the spread because they wanted in now, at market price. CVD sums those decisions: trades executed at the ask (aggressive buying) count as plus, at the bid (aggressive selling) as minus. The result is a running balance of wanting: who is paying for immediacy — demand or supply.

That is why CVD says something price alone does not. Price can rise on negative CVD (aggressive supply absorbed by passive demand — “silent absorption”) and fall on positive CVD (aggressive demand walking straight into a passive wall — “distribution”). The divergence between price and flow is the most interesting phenomenon in the entire System — and the most frequent subject of our Logs.

How we measure it on the bridge#

Heniu tracks CVD separately for the three bodies of the System: the NDX Star (cash market), the NQ Probe (futures) and the QQQ Dyson Sphere (ETF). Scale matters: on NDX, millions of shares are ordinary breathing; hundreds of millions are an event. The classification thresholds (from “supply test” to “demand singularity”) are hard-coded in the system’s configuration — the narrative may dress the numbers in cosmos, but it may not move them.

What CVD does not do#

It does not predict the future — we measured that on our own system and the honest result was a coin flip. CVD describes the current state of the fight between demand and supply; it is a description of force, not a prophecy of direction. On this blog it is used strictly that way.
