Test setup
Compare feed arrivals from a synchronized recording environment.
Methodology / From observations to estimates
A disciplined view of the market.
We analyze order-book and price data across venues, their discrepancies and how they change over time.
01 / Established methodology
Observe. Reconcile. Estimate.
01
Order books
Observe price and market state
02
Normalize
Remove margin; reconcile observations
03
Consensus
Estimate a coherent fair price
04
Deliver
REST snapshots or SSE updates
Remove margin, retain context.
De-vigging removes the margin implicit in quoted prices. We normalize outcome probabilities, reconcile current observations and form a consensus estimate. A fair-price estimate is a reference, not a guarantee of a game’s true probability or outcome.
Stale information needs a signal.
The feed carries a recent flag and a price timestamp, at. If a current consensus cannot be formed, the last price can remain with recent: false. Consumers should use both fields, rather than assuming every returned price is current.
Price and quoting state are distinct.
A bet-stop can ask a market maker to widen or pull while prices continue to update. The widened-state flag marks a cautious return. Neither signal guarantees protection from loss. Numeric uncertainty remains under development.
02 / Interpreting the signal

Benchmark study in progress
Current-stack measurements are being collected. No speed advantage or absolute processing latency is published here.
Timing definition
Measure time to halfway repriced around official scoring plays. Distinguish receipt time from event time.
Sample & statistics
Publish dates, leagues, sample counts, median and relevant percentiles once approved.
Caveats & review
Document missed changes, stale arrivals, event-clock limitations and comparator disclosure approval.
Know the limits.
Coverage is limited to the listed leagues and winner markets. Market availability and source freshness vary. Live scores follow upstream reporting and are not a substitute for an event-time reference.
Fixtures use official league feeds where available and confirmation sources where supported. College football has no independent confirmation source yet. Confirmation gaps can use a grace period; grades require agreement and may remain unpublished when evidence conflicts.
Six leagues. One coherent view.
Built for the decisions behind the price.
