Closing Line Value (CLV): the proof your edge is real
Imagine you buy a shirt for $50 and an hour later the same shop sells it for $60. You got the better price — even before wearing it. CLV is exactly that idea, applied to bets: did you get a better price than the market's final price?
What CLV means
The 'closing line' is the final price the market settles on, right before the game starts. CLV compares the price you took to that closing price. Example: you take +150, and the market closes at +130. The price moved toward your side — you beat the closing line, so you have positive CLV. You get negative CLV if the market closes at a worse price for you, like +170.
Why CLV is the best early signal
Here's the surprising part: CLV doesn't depend on whether you won or lost the bet. A pick with positive CLV is a sign your information was better than the market's — even if the team lost that night. Over many bets, consistently positive CLV is the strongest early proof that your edge is real, before the win/loss record has enough data to say anything.
CLV vs winning bets
You can win a bet with negative CLV (you got a bad price and got lucky) or lose with positive CLV (good price, unlucky result). The short-term result is noisy; the price you got is information. VEKTORIUM calculates CLV on every settled pick so you can watch this signal instead of just counting wins and losses.
