CLV Tracking
Track your closing line value across every sportsbook
Wins and losses are noisy. Closing line value (CLV) tells you whether your bets actually beat the market — and Edgeline measures it automatically on every futures position you hold, across 50+ books.
Start free →What is closing line value?
Closing line value is the difference between the odds you got and the line the market settled on at close. Bet a team at +600 and it closes at +450, and you captured positive CLV — you beat the number the market converged on. Because the closing line is the sharpest price available, consistently beating it is the clearest sign you're making +EV decisions.
Why CLV predicts profit better than your record
Over a single bet, variance dominates — a great decision can lose and a bad one can win. Over a season, CLV tracks long-run profit far better than win-loss record, because it measures decision quality, not luck. A bet that loses but had positive CLV was still the right call. That's the signal serious bettors optimize for.
How Edgeline tracks CLV for you
Add a futures position (manually, by CSV, or by screenshot) and Edgeline benchmarks it against the best available line across 50+ sportsbooks, then keeps updating as odds move toward the close. Your CLV sits right on each position card, and the AI agent flags when a line move means you should consider holding, hedging, or exiting.
Frequently asked questions
What is closing line value (CLV)?
CLV is the gap between the odds you bet and the closing line the market settles on. Positive CLV means you beat the market's final price — the strongest available indicator of a +EV bet.
How do you calculate CLV?
Convert your entry odds and the closing odds to implied probabilities (after removing the sportsbook's vig), then compare them. Edgeline does this automatically for every position against a de-vigged consensus of 50+ books.
Is Edgeline a sportsbook?
No. Edgeline is an analytics tool — it tracks and evaluates your positions but never places, facilitates, or accepts bets. You bet wherever you already do; Edgeline measures how well you're doing.

Futures and outrights across NBA, NFL, MLB, NHL, golf, tennis, and more — championship winners, division/conference, win totals, awards, and similar long-horizon markets.
Is there a free version?
Yes — Edgeline is free to start. Paid tiers add deeper analysis, more tracked positions, and alerts.
How is fair value determined?
Edgeline removes the vig from each book's price and blends a consensus across 50+ sportsbooks, layering in season data and AI reasoning to estimate a position's fair value versus its current market price.
