Bet CLV Tracker: Closing Line Value vs Sharp Odds

What does Bet CLV Tracker: Closing Line Value vs Sharp Odds do?

Bet CLV Tracker grades your bets against the closing line. You give it a list of bets with decimal odds and one or more bookmaker odds datasets captured just before the games started. It matches each bet to its game, removes the margin from the sharp bookmaker's closing price to get the fair closing odds, and returns closing line value as a percent, whether you beat the close and the expected value at close. A summary record gives the average CLV and the share of bets that beat the closing line.

Why use Bet CLV Tracker: Closing Line Value vs Sharp Odds?

• CLV is the fastest signal of long-term betting edge.
• Uses the sharp bookmaker's no-vig close, not a raw price.
• Matches bets to games across bookmakers despite name differences.
• Summary with average CLV and beat-the-close rate.
• Works with the odds datasets you already collect.

What makes this different

Most CLV tools are closed apps tied to one sportsbook import. This Actor takes plain bets and any bookmaker odds datasets, uses a proportional no-vig closing price from the sharp book you choose, and gives per-bet CLV plus a summary you can chart or store.

How it works

1. Your input — paste your bets and pick the closing-odds datasets.
2. The Actor collects it — the Actor matches each bet to its game and removes the sharp book's margin.
3. Your output — you get CLV per bet and a summary record.

What data can you extract?

The dataset has 17 fields per row:

Field	Type	Description
id	string	Your bet id.
event	object	Home, away and start time.
market	string	moneyline or total.
line	number	Total line.
selection	string	home, draw, away, over or under.
bookmaker	string	Bookmaker you bet with.
betOdds	number	Your decimal odds.
stake	number	Your stake.
status	string	matched, no-closing-price, incomplete-closing-market, or not-a-closing-snapshot.
closingOdds	number	Sharp bookmaker raw closing odds.
closingFairOdds	number	No-vig fair closing odds.
closingFairProbability	number	No-vig fair closing probability.
clvPercent	number	Closing line value in percent.
beatClosingLine	boolean	True when CLV is positive.
expectedValueAtCloseUnits	number	Expected value at the close in stake units.
hoursBeforeKickoff	number	Hours between the closing quote's scrapedAt and kickoff (negative if scraped after kickoff); null when unknown.
demo	boolean	True for the built-in sample.

How to use Bet CLV Tracker: Closing Line Value vs Sharp Odds

1. Open the Actor and go to the Input tab.
2. Paste your Bets as JSON, pick the closing Odds datasets, and press Start. With no input it runs a built-in sample.
3. Optionally set filters and a Max results limit.
4. Click Start. A default run finishes in under a minute.
5. Open the Output tab, then download the dataset or connect it to your tools.

Input Parameters

Parameter	Type	Required	Default	Description
bets	array	No	[]	Bets to grade, as JSON. Each needs home, away, market (moneyline or total), selection (home, draw, away, over, under) and decimal odds; optional startTime, line (for totals), stake, bookmaker and id. Example: {"home":"Arsenal","away":"Chelsea","market":"moneyline","selection":"home","odds":2.2,"stake":10}. Leave empty to try a built-in sample.
oddsDataset1	string	No	—	Closing odds: a dataset from a bookmaker odds Actor run taken just before the games start (it must include the sharp bookmaker).
oddsDataset2	string	No	—	Another dataset of the same kind.
oddsDataset3	string	No	—	Another dataset of the same kind.
oddsDataset4	string	No	—	Another dataset of the same kind.
sharpBookmaker	string	No	"Pinnacle"	Bookmaker whose no-vig closing price is the fair closing line. Must match the bookmaker field in the datasets.
maxStartDiffHours	number	No	3	Listings count as the same match when start times are within this many hours.
closingWindowHours	number	No	6	A sharp price is only treated as a genuine closing line when it was scraped within this many hours before kickoff (and not after kickoff). A snapshot outside this window is reported as not-a-closing-snapshot instead of being used as if it were the close.
maxResults	integer	No	5	Maximum number of bets returned. Default is 5 for a quick test; set 0 to return everything available.

Output Data

clvPercent is bet odds times the closing fair probability minus 1, as a percent: positive means you got a better price than the fair closing price. status is no-closing-price when the game or market was not found. A SUMMARY record in the key-value store has the average CLV and the beat-the-close percentage.

Tips for Best Results

• Default is 5 results for a fast test. Set the max to 0 to return everything available.

Known Limitations

• Closing prices are only as close as the datasets you capture; run the odds Actors just before start times.
• Only moneyline and total bets are graded.
• Total bets need the same line as the sharp book's closing line.
• Team matching is fuzzy; unusual name differences can leave a bet unmatched.
• A closing price is only accepted when it was scraped within the configured window before kickoff (default 6 hours) and not after kickoff; a snapshot outside that window is reported as not-a-closing-snapshot rather than used as if it were the close.
• A three-way sport's closing quote missing its draw price is reported as incomplete-closing-market, not silently priced as two-way.
