Closing Line Value, explained
CLV is the single most honest number in betting — and the one tipsters never show you. Here's what it means and why we built the brand around it.
The one-sentence version
Closing Line Value (CLV) is whether the price you took was bigger than the price the market settled at. If you backed a horse at 4.0 and it started at 3.0, you beat the close — you had positive CLV — whether or not it won.
Why it matters more than last week's winners
Betting markets are efficient: by the off, the closing price reflects everything the crowd knows. Consistently beating that closing price means your information arrived before the market caught up. Over a large sample, positive CLV is the strongest statistical predictor that a selection process has a genuine edge — far more reliable than a run of winners, which variance produces by chance.
Why it's the hardest metric to fake
Strike rate and profit can be cherry-picked, back-fitted or quietly reset after a bad month. CLV can't: it requires you to have registered a price before the off and compares it to a public closing price anyone can verify. That's exactly why we register every tip pre-race and grade it against the SP — and why we'll report CLV openly as our record builds.
How we use it
- Every tip is logged at the price available, before the race.
- After the off, we compare that price to the starting price (SP).
- The share of tips that beat the SP is our headline CLV figure.
- We show it with sample size and confidence intervals — no rounding up.
Honesty note
A high CLV doesn't guarantee profit on any given day — variance is real, and place markets, commission and available liquidity all matter. What CLV tells you is whether the process is finding value. That's the thing worth paying for. See the record →
