What is Closing Line Value in Sports Betting? How to Track Closing Line Value

Just fill in your number of bets, your yield / ROI%, and your average odds from your bet sample, and the p-value calculator will do the rest. Without adjusting for the margin, you might think you have a positive CLV since the odds taken (2.50) are higher than the closing odds (2.30). Suppose you placed 100 bets, and 60 of them have a positive CLV.

CLV influences your betting strategy by providing a benchmark to measure the quality of your wagers. Consistently achieving positive CLV suggests you are predicting market movements better than the average bettor, indicating a robust betting model. It helps you identify which strategies are effective and where adjustments may be necessary, ensuring that you capitalize on value betting opportunities more efficiently. In this example, placing a bet at -105 yields a positive CLV since the closing line moved to -115, showcasing that the initial bet was well-timed and at favorable odds. Accumulating positive CLV over time is a hallmark of a successful sports betting strategy. Finally, while CLV is a reliable indicator, it should be used alongside other performance measures to gain a complete view of betting skills.

They focus on whether you’re consistently getting better numbers than their closing line. For example, you could lose nine out of ten bets but still be recognized as a sharp bettor if you consistently beat the closing line. CLV illustrates the effectiveness of a bettor’s analysis of the market, its prediction of the changes in odds.
