What this tool calculates
Probability CLV compares closing implied probability with the probability implied when the bet was placed. Odds CLV compares the placed decimal price with the closing price.
Probability CLV = (1/close − 1/placed) × 100 percentage points. Odds CLV = (placed/close − 1) × 100%.
Results are informational. Confirm final grading, limits, deductions, and promotional terms with the operator.
Worked example
Placed prices 2.10, 1.90 and 2.50 can be paired with closes 2.00, 2.00 and 2.40 to produce two transparent average CLV measures.
