Per-venue strip + median blend. If a venue's number diverges by 5% for 5 consecutive ticks, it gets dropped — and the remaining two still constitute a quorum. DVOL (1 venue) and BVIV (2 venues) cannot do this.

What makes VolX different.
read the methodology →Every published tick carries a [0, 1] confidence score that collapses when venues are missing, quotes are stale, or the strike range is thin. Downstream consumers can filter, gate, or weight by it.
Source, methodology, validation procedure — all public. Runs locally on a laptop with one command. No paid feed, no API key gate, no cloud dependency.
