Understanding CLV
Closing Line Value (CLV) measures whether you consistently beat the closing odds. The closing line is the sharpest price, incorporating maximum information.
Getting better odds than closing line indicates you're finding value before the market corrects. Positive CLV compares prices; it does not guarantee profitable results.
Consistently worse odds than closing suggests you're betting after sharp money moves lines against you.
CLV % = ((Your Odds / Closing Odds) - 1) × 100
Target: Maintain +3% average CLV or higher across large sample (500+ bets).

How to use this closing line tracker
Record comparable prices
Add a description that identifies the event, market and selection. Enter the decimal odds actually accepted, followed by the closing odds for that identical selection. Keep the same reference bookmaker or closing-price source across comparable entries. A changed handicap or different goals line is a different proposition, even when the team name matches.
A hypothetical price comparison
Imagine staking R100 at odds of 2.20 before the same selection closes at 2.00. CLV % = (odds taken / closing odds - 1) × 100. The calculation (2.20 / 2.00 - 1) × 100 gives 10%. If successful, that illustrative ticket returns R220 instead of R200 at the later price. The R20 difference concerns potential return; it is not money earned simply by recording positive CLV.
Read the summary without overreaching
Positive CLV means the accepted decimal price exceeded the closing reference. A negative figure means it was lower. This tracker averages entry percentages equally, so a small wager carries the same weight as a large one. Neither the average nor the beat rate proves profitability. Review actual settlements separately.
When should I capture closing odds?
Use a consistent point just before the event begins and note the time in SAST in your own records. Avoid substituting an in-play price after a goal or other material event.
Can a losing ticket have positive CLV?
Certainly. Price movement and the final sporting result answer different questions. Do not raise stakes to turn a favourable comparison into cash. Keep your original loss boundary and retain a separate copy of important entries.
