The best odds feed for live arbitrage.
Live arbitrage is the most demanding use of an odds feed: the fresher and more efficiently delivered the data, the more you can act on before it closes. Here is what matters at the live end specifically, and an honest read on where OddsRelay fits — and where no feed can promise the world.
Who this is for
Teams building live or fast arbitrage tools where freshness and delivery efficiency are the binding constraints, not finished analysis.
What matters for live arbitrage
Freshness, above all
At the live end, how current the data is decides how much you can act on. A tight cycle and a verifiable timestamp are non-negotiable.
Delivery that keeps up
You poll constantly, so ETag/304 and gzip are not optional — they are what lets you stay fresh without runaway cost.
Breadth that still scales
More books in one schema means more live discrepancies, as long as freshness holds across them.
Honesty about limits
No feed is instant. The right partner states a cadence, timestamps payloads, and does not promise zero-latency miracles.
Evaluation criteria
| Criterion | What to look for |
|---|---|
| Verifiable freshness | A tight, timestamped cadence plus a live freshness surface you can watchAt the live end you need to see currency, not trust a claim. |
| Delivery | ETag/304 + gzip for constant pollingYou cannot stay live if polling is expensive. |
| Cadence alignment | Poll on the matcher cycle, not blindlyAligned polling stays current without wasted requests. |
| Breadth | Many books in one schema, kept freshMore comparable prices mean more live opportunities. |
| Honesty | No zero-latency or guaranteed-arb promisesSuch promises are a sign of overstatement. |
Where OddsRelay fits
- The feed refreshes on a tight cycle and timestamps every payload, so how current a price is is never a guess.
- The /coverage surface publishes the live processed-at freshness, so you watch the data move rather than take a latency number on faith.
- ETag/304 and gzip make constant polling efficient, so you stay current without runaway egress.
- Poll on the matcher cycle rather than blindly, and you stay aligned to when the board actually changes.
- Deep UK coverage in one schema, bet365 included, gives a wide live surface — see the arbitrage page for the full breadth argument.
An honest caveat
Live arbitrage pushes any feed to its limit, and we will be straight with you: no feed is instant, and none can guarantee a live arb survives to execution. OddsRelay is built to be as fresh and efficiently delivered as we can honestly stand behind, with the freshness published so you can judge it — but if your strategy needs sub-second guarantees, no honest provider can promise that, and you should be sceptical of any that do.

Live coverage, freshness and status are published on the coverage dashboard.
Questions
Is the feed fast enough for live arbitrage?
It refreshes on a tight cycle, timestamps every payload, and publishes freshness live so you can judge it against your needs — rather than us claiming a number you cannot verify. Start a trial and watch the timestamps move.
Can you promise an arb will still be there when I act?
No, and neither can any honest feed — prices move. We give you the freshest, most efficiently delivered picture we can stand behind; execution is your tool's job.
Why is delivery efficiency part of 'live'?
Because staying live means polling constantly. ETag/304 and gzip let you do that cheaply, so cost never forces you to poll less and fall behind.
