Daily up-or-down on the major pairs, the closest thing to a coin flip the venue sells. Except currencies drift, sessions have rhythm, and the fair line is rarely exactly 50. I price the flip properly and act only when the table's number is off mine by more than the house's own edge.
If the coin isn't bent, I don't call the flip. Most days most pairs price fair. The winning move at a fair table is to keep your chip, and I'll tell you so.
One token sweeps all eleven daily fixes, measuring my fair-value band against every venue book, and deals you the single best interval-disjoint divergence, or a pass with the working shown.
A fix, a session, a central-bank morning: ask and the engine answers with the band, the book, and the gap.
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, eleven pairs, one fix a day each. The scan covers the whole table.
The fair band is built from the pair's own behavior into the fix; the venue's Up book is measured against it. Band and book disjoint beyond spread, or no deal.
The call prints here with its full reasoning, timestamped. Every call joins the book. There is no delete key in this building.
Almost. And that's the point. The venue prices it LIKE a coin flip; the currency behaves like a weighted one. The weight is small, so I only deal when the mispricing is bigger than the house edge, which is exactly why most days you'll see a pass.
The eleven majors the venue runs daily fixes on. When it adds chairs, the table grows.
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.
