Best for
The best odds feed for arbitrage.
Arbitrage tools surface discrepancies across books and against the exchange. The feed underneath decides how many you can find and how current they are. Here is what matters for arbitrage specifically, and an honest read on where OddsRelay fits.
Who this is for
Teams building arbitrage or value-detection tools that compare prices across many books and against the exchange, and need breadth and freshness more than finished analysis.
What matters for arbitrage
Breadth in one schema
The more books normalised to one shape, the more discrepancies your tool can surface — coverage and consistency together.
Exchange back/lay context
Arbitrage and value calculations need exchange prices alongside bookmaker odds, not just the books.
Freshness you can verify
A tight refresh cycle and a processed-at timestamp, so detection runs on current prices you can date.
Efficient polling
ETag/304 and gzip, because arbitrage means polling constantly and re-downloading an unchanged board gets expensive fast.
Evaluation criteria
| Criterion | What to look for |
|---|---|
| Breadth | Many books normalised to one event/selection modelDetection scales with the number of comparable prices. |
| Exchange context | Exchange back/lay alongside bookmaker oddsBack/lay and value calculations depend on it. |
| Freshness | A tight cadence + a timestampStale prices produce phantom opportunities. |
| Polling efficiency | ETag/304 + gzipConstant polling has to stay affordable. |
| Honesty | No guarantee an arb survives to executionPrices move; a feed that promises otherwise is overstating. |
Where OddsRelay fits
- Deep UK coverage normalised to one schema gives arbitrage detection a wide surface.
- Exchange back/lay prices sit alongside bookmaker odds for value and back/lay calculations.
- A tight, timestamped refresh cycle lets you reason about how current each price is.
- ETag/304 and gzip keep constant polling efficient.
- bet365 is included, adding one of the most-watched books to your detection set.
An honest caveat
No feed can guarantee an arbitrage will still be available when you act — prices move, and any provider promising otherwise is overstating. OddsRelay gives your tool the widest, freshest, timestamped picture we can stand behind; execution timing is your tool's job. And if you want finished, rated opportunities rather than raw breadth, that is the matched feed, not this.

Questions
Do you guarantee arbitrage opportunities?
No — and be wary of any feed that does. Prices move; opportunities open and close. We provide a wide, current, timestamped market picture so your tool detects them on the best data available; acting in time is the tool's job.
Is exchange data included?
Yes — exchange back/lay prices are available alongside bookmaker odds, which arbitrage and value calculations need.
Why does polling efficiency matter so much for arbitrage?
Because you poll constantly. Without ETag/304 and gzip you re-download an unchanged board every time, which forces you to poll less to control cost — and polling less means catching fewer opportunities.
