Normalised odds
Normalised odds are prices mapped to consistent selections, markets and formats across books, so they can be compared like for like.
Different bookmakers label markets and selections differently and quote in different formats. Normalisation maps them to one schema, so the same selection lines up across every book and the exchange.
Normalisation is what makes comparison, arbitrage and matching correct rather than accidental. It is the unglamorous core of a usable feed, and the reason raw scrapes are worth so much less than clean data.
OddsRelay delivers this as part of one already-matched feed. See live coverage on the coverage dashboard.
