Every pick on PickAuditor has two prices attached: the odds it was graded at, and the odds available on the same selection when the market closed. Closing line value is the gap between them, and over a long enough record it says more about a service than its win rate does.
What the closing line is
Betting markets move from the moment they open until the event starts. Each move is the market absorbing information: team news, money from informed bettors, corrections to an opening price. The last price before kickoff is the closing line. By then the market has done most of the work it is going to do, and the closing price is, in general, the sharpest public estimate of the outcome's probability that exists before the game. PickAuditor uses Pinnacle's closing price where it is available; the methodology says what happens when it is not.
The definition
For one pick:
CLV = (odds used ÷ closing odds − 1) × 100
Odds used is the decimal price the service quoted when it published the pick, or the market price at the moment we captured it if the service quoted none. Positive CLV means the service's price was higher than the close: the market later moved toward the service's side. Negative CLV means the market moved away from it.
- Odds used (quoted by the service)
- 2.10
- Closing odds, same selection and line
- 1.95
- 2.10 ÷ 1.95 − 1
- 0.0769
- CLV
- +7.7%
The pick had value against the close whether or not it won. Reverse the two prices — used 1.95, close 2.10 — and CLV is 1.95 ÷ 2.10 − 1 = −7.1%: the market moved against the pick, again regardless of the result.
Why it is read next to ROI
A won-lost record over 50 or 100 picks is mostly noise. At typical prices a service with no edge will post a profitable 100-pick stretch fairly often, and a service with a real edge will post a losing one. CLV settles faster: whether the market moved toward a pick is decided by kickoff, does not depend on the bounce of a ball, and its average converges over far fewer picks than ROI does.
Two combinations are worth noticing on a profile. Positive ROI with negative average CLV over a short period is the pattern of a service running hot: it has been paid for picks the market was moving against, and that tends not to continue. Negative ROI with positive CLV is the reverse: the picks were on the side the market moved toward, and the results have not caught up. Neither is a forecast; both are a reason to open the 365-day row before the 30-day one.
- Service A · 90-day ROI
- +4.0% (n=120)
- Service A · average CLV
- +2.6% (n=112)
- Service B · 90-day ROI
- +4.0% (n=118)
- Service B · average CLV
- −3.1% (n=104)
Identical returns. A's picks were priced above the close on average; B's were priced below it. Only one of the two records is explained by something other than results falling its way.
What CLV is not
- It is not profit. A service can beat the close and still lose over a period. CLV is a statement about the quality of the price, not the money.
- It is not always obtainable. A service may quote a price from a bookmaker that offered more than Pinnacle did at the same moment; measured against Pinnacle's close, that pick looks stronger than it would against the quoting bookmaker's own close. Each pick shows whether its odds were the service's quote or the market at capture.
- It ignores line changes. On spreads and totals the number moves as well as the price. A pick on over 2.5 is compared with the close on over 2.5, not on over 3.0; if no closing snapshot has that line, the pick has no CLV and is left out of the average.
- It shrinks with late captures. A pick first seen ten minutes before kickoff leaves the market almost no time to move, so its CLV is near zero by construction.
How PickAuditor computes it
Per pick, exactly as in the formula. Odds used is chosen in this order: the service's quoted decimal price if it showed one above 1.00; otherwise the market snapshot at capture time, Pinnacle preferred; otherwise the nearest snapshot taken no later than 30 minutes after capture. Closing odds are the reference bookmaker's closing snapshot for the same selection and line; when none was recorded, the last snapshot before kickoff is promoted to closing. The average on a profile is the mean over picks that have both prices, and its n is shown separately because it is often smaller than the ROI n: picks without a reference price drop out of CLV but not out of hit rate.
The leaderboard can be ordered by average CLV, subject to the same 30-pick floor as every other metric. One of the site's consensus meta-models, clv_weighted, lets only services with positive 90-day CLV vote and weights them by it; it is graded in public like everyone else.
Reading it on a profile
Read the sign, the n and the period together: +1% over 400 picks in 365 days says more than +6% over 35 picks in 30 days. Compare it with ROI in the same row, and if the two disagree in sign, prefer the longer period before forming a view. Then open the record page. A service whose average is carried by a few large moves on thin markets looks different from one that beats the close by a little on most picks, and only the per-pick column shows which is which.
