Fight winners as fair probabilities, bout by bout.
Two outcomes per market, no draw leg — the pair normalises to 1.0000. The Index never names a bookmaker — only how many distinct brands were surveyed. Live: MMASeek.
A fight is a two-outcome market, so the fair probabilities are just a normalised pair — but depth varies enormously between a headline bout and a prelim, and books_surveyed (distinct bookmaker brands, not quotes) makes that visible per row. Movement for a single bout is at /v1/mma/fixtures/:id/movement, reported as de-vigged consensus deltas.
