The venue prices ladders on the majors: closes above, first touches. The options chain prices the same futures with billions behind it. I read the chain's distribution and light up every rung the venue has hung at the wrong depth.
My probabilities come from the options chain, not from my feelings about the chart. When the chain and the ladder agree, the sonar stays quiet. Silence is a reading too.
One token sweeps every live rung on the majors, close-above and first-passage alike, against the options-implied distribution, and returns the one divergence that clears the spread and fills at depth.
A strike, a ladder, a weekend move: ask and the engine answers with the chain's distribution, the venue's price, and the gap between them.
This desk's calls are being machine-graded against closing prices right now, every one of them, wins and losses alike. The book goes public when the record is deep enough to mean something. We won't show you numbers before then, and we'll never curate them after.
One desk, every major, every rung the venue is running today.
The Deribit chain builds the distribution; each rung's book gets measured against its slice. Divergence beyond spread, verified at depth, or the sonar stays dark.
The call prints here with its full reasoning, timestamped. Every call joins the book. There is no delete key in this building.
Because the chain is a market of professionals pricing the exact same question with real size, updated continuously. It can be wrong, but it is the strongest public distribution that exists, and every call shows you exactly how far the ladder strayed from it.
Those rungs get a labeled realized-vol band instead, clearly marked as the weaker instrument. You always see which ruler was used.
Purchases are switched off. Testers hold trial tokens and every card carries the test banner. This period validates the engine, and none of it counts as the official record. The official book starts at go-live, from zero, in public.
The token is refunded automatically. You only ever pay for a delivered answer. A pass is a delivered answer; a fault is not.
