What is Closing Line Value?
Closing Line Value (CLV) measures whether you're getting better odds than the final market price. The closing line is considered the most efficient because it incorporates all available information right before the event starts.
Professional bettors track CLV as the primary indicator of long-term success. Consistently beating the closing line suggests you have an edge over the market, even if short-term results vary due to variance.
A positive CLV means you locked in odds better than where the line closed. For example, betting -110 on a line that closes at -115 gives you approximately 2.3% CLV edge.
