Frequently Asked Questions
CLV Calculator - Are You Beating the Market?
Closing Line Value (CLV) is the gold standard for measuring betting skill. If you consistently get better odds than the closing line, you're beating the sharpest market in the world.
Our CLV Calculator lets you manually check any bet's CLV and automatically tracks your historical CLV performance across all recorded bets with closing odds.
Professional bettors focus on CLV above short-term results. A bettor with positive CLV will profit long-term, even if they experience short-term variance losses.
