Best Closing Line Value Betting Tools

It is nearly impossible to predict what kinds of impacts and external effects will change the current odds and where they will settle before the game starts. Fortunately, there are betting tools and software that specialize in predicting the CLV.

Aggregating thousands of data points, tracking line movements, and assessing the public sentiment, they can give you a rough idea of where the lines are heading, and when is best to stake your wagers.

Closing Line Value in Sports Betting

Predicting closing line value in sports bets is not a niche strategy by any means. It is an integral part of all advanced sports betting strategies, from EV+ strategies to arbitrage betting and even futures betting strategies.

At the base of CLV betting, the goal is to determine which way the betting lines and odds are moving, and when you can get the best value for your sports bets. It may be a matter of cents on each line in most cases, but those can add up quickly if you bet frequently. And over time, that extra value can make all the difference between a profitable betting strategy and a losing one.

On this page, we will analyze how closing line value works and showcase all the best betting tools that can give you an edge.

Best CLV Betting Tools

By comparing statistics, aggregating the odds prices in real time, and analyzing these against the historical lines, these betting tools are designed to help you beat the CLV. The best tools also have retrospective CLV bet trackers, so you can measure how well you fare against the CLV in the long run, and tweak your strategy for future success.

One of the most well-known betting tools across the US, OddsJam caters to intermediate to advanced bettors. OddsJam has several packages to offer, but for CLV betting, it is best to opt for the standard Gold package, Platinum, or the Starter Screen Plan. The Gold includes virtually everything you need, with betting strategies across 40 US sportsbooks, devigged odds, positive EV, arbitrage bets, parlay builders, and promo conversion. OddsJam also has an elite bet tracker tool, through which you can set up CLV notifications, check the closing lines on all your logged wagers, sync your sportsbooks, get the percentage you beat the CLV by, and check CLV by each US sportsbook. Plus, you can follow any other users who have set their bet trackers public – something you can also do to get followers.

What we really like about OddsJam is that it doesn’t just devig odds and display the best wagers across all the top US books, peer-to-peer betting apps, and prediction markets. It also has historical line movements, projections, and a depth of analytical data that you can use to gain an edge. OddsJam has the best sports coverage out there, with over 20 categories covering sports events from all over the world.

The only snag is that the Gold package may be too expensive for some users. Platinum costs even more, but comes with 1:1 coaching and live odds – where the EV and arbitrage ROI is twice as high. But if you want something a little more affordable, you can opt for the Starter Screen subscription, which comes with premate and live odds coverage, real-time updates, line movement history charts, and the bet tracker. It doesn’t have the arbitrage strategies nor the promo conversion, middles, and other features OddsJam has to offer. But for pure CLV hunting and value betting, the Starter Screen offers bettors a shot to gain the insights at a more affordable rate.

Monster.Bet is a highly versatile platform that went live in 2024. Monster.bet has a plethora of features, with EV+ finders, detailed odds analysis, sharp money detection, arbitrage and middles betting scanners, a data lab, daily AI picks, and its very own MonsterGPT virtual AI betting assistant. There is a lot to discover here, but specifically for CLV betting, you will need the EV tool, odds screen, and the Data Lab. These scan the odds, identifying the mathematically best value, and with the data lab you can get detailed projections and hit rate matrixes.

The EV and Data Lab features are available with the Odds Pro and Monster Pro packages, though if you just want the Data Lab, for statistical analysis, you can get it with any of the packages. You can also get subscriptions that include the MonsterGPT, which is an AI assistant that responds to specific prompts. The Sharp Money tool gives you even more insights for CLV, with historical line movements and projected future lines, so you don’t have to do any guesswork yourself.

Trademate Sports does odds comparison, EV+ strategies, stake sizing optimization, and also CLV tracking. It has a user friendly interface and is designed to pinpoint bets with high value, and determine the line movements. The betting tool uses historical data and line positions to create projections, and show you which way the markets will move. With the historical CLV tracking charts, you can also check previous movements out yourself, and compare them with the various books that Trademate Sports covers.

While there are numerous subscription packages offered, when we reviewed Trademate Sports we found that only the US subscription is really worthwhile for US bettors. It is affordable, albeit with limitations in the sports covered and the number of US sportsbooks. There are only 10 sportsbooks covered, and Trademate Sports US only covers the major sports and college events. If you pay for the Trademate Sports Core package, you unlock far more sports and books, but it comes at a far higher price. Trademate Sports is a highly recommended option if you bet at the top US sportsbooks and only intend to bet on the major sports.

Unabated is very popular in the US, and for all the right reasons. The sportsbook coverage is ample, with all the top US books, social sportsbooks, peer-to-peer betting apps, and even prediction markets. The tool covers all the major US sports, and has a great depth of betting markets, extending to all the alternate player props, futures, and partial game derivatives. Unabated devigs odds, shows you the sportsbook hold, and has speedy odds scanners to present you with the best lines for your bets.

It also has simulators for props and futures bets, not just giving you the estimated outcomes but accumulative charts so that you can gauge the different possible outcomes and plan ahead. But for CLV betting, the best tools are the line movement history and the compare lines functions, which are available on the main odds screen. Simply pick any line, and you can check its historical movements or compare the movements of two lines side by side. You also have a plethora of calculators, including a basic CLV calculator.

OddsShopper may be an odds comparison betting tool first, but it has many features that can enhance your betting strategy. It scans odds from over 10 top US sportsbooks, as well as peer-to-peer betting apps, social sportsbooks, and prediction markets. You can check the Edge, True Odds, Width, Outlier, and Hold on each bet, and even get live charts with line movements from as many books as you like. OddsShopper scans loads of betting markets, including game lines, player props, team props, player futures, and team futures. The coverage includes the NFL, NBA, MLB, NHL, college sports, top soccer leagues, golf, tennis, and even the UFC.

But that’s not all. Besides assessing line movements and the data behind the betting lines and odds, you also get a Portfolio Lab where you can set templates to compare ROI and estimate user bets per day at different sportsbooks and get an idea of where the value is highest. As I explain in more detail in my OddsShopper review, the platform also has a Parlay Builder, Pick’em Builder, Mass Entry (for placing many bets at once), arbitrage wagers, bankroll tracking, and a Top Bets feature that can be set to your preferences. It is also worth checking the Tails Expert Picks to look for highly rated User picks and Expert bets. But for closing line value, the main tool is the odds screen, where you can compare lines and scan the top US books for the best value.

User rating (9)

A fully mobile-optimized betting tool that has plenty of customizable features, Line Prophet is an affordable and smart option for hunting value. It doesn’t have massive sports coverage, only extending to the 4 major US sports leagues and college basketball and football. However, Line Prophet goes to great lengths to analyze historical data, explore niche player props bets, and give you a massive backlog of metrics to help you look for value. It functions as a statistical research tool, an odds comparison and value detection tool, and also has predictive models and a Game Chat AI.

The line movements are accurate, and you can also use the AI-powered custom betting trend tool, public sentiment charts, and get AI-powered predictions. You can build the context here, setting your own filters, analytic weighings, and use the live trend builder to explore new betting angles. The Lines data is pretty accurate and reliable, updating in near real time, and you can go into great depth with player props. It is a lot more affordable than other options here, but we have to point out that the sports coverage and the betting markets aren’t as extensive.

Beating Closing Line Value

There are many means through which you can predict the closing line value and accurately estimate the line movements. Betting tools and CLV predictive software can use metrics to project the market movements at different sportsbooks, the converging prices, and pick out those outliers with larger discrepancies or higher value.

A word of warning though. These tools can only predict based on the data at hand; they cannot predict the future. Say a player picks up an injury or gets sick, a player falls out with the coach and is dropped for the next game, or an unforeseen weather change can impact the odds significantly, but these cannot be predicted ahead of time. What the betting tools can do is look at previous line movements, historical statistics, and analyze the current odds. With data-driven algorithms and formulae, they can analyze patterns and trends, giving you rough estimations of where the lines will move.

The results you get can vary drastically based on the betting tool you pick. Because they all have their own proprietary algorithms and data point analysis.

Statistical Analysis

Stats-driven betting tools tend to focus more on the historical performances, team H2H data, and player stats to gauge winning probabilities. These are important, but not crucial to CLV betting. Closing line value betting revolves around the odds and the line prices.

With early odds (right after they are launched), or with futures bets, statistical analysis can be extremely handy. You can avoid short odds and look for the higher value picks by gauging the odds against the given stats.

Good for: Early pregame wager odds and futures bets

Odds Comparison

Ideally, your betting tool should compare the odds at more sportsbooks, and the scanners should be as close as possible to real-time as possible. When tracking line movements, if your betting tool has a 10-second latency, you can miss out on big opportunities. It also impacts the line movement comparison charts, as you miss out on prices that may change in a matter of seconds.

In theory, betting markets tend to start wide and then slowly converge when the game draws closer. The closing lines are generally nearly identical, or they may differ, but by a matter of cents on each line. If you want to beat the CLV, you have to be aware of the movements across more sportsbooks, and then you can single out any books that are slow to update their odds, or that still hold onto their previous lines.

Good for: Finding discrepancies and deviated prices

Historical Line Movements

A betting tool that tracks the previous lines and has features to compare these is perfect for CLV betting strategies. Betting lines will not move in one direction, they can go up or down based on public sentiment and demand, as sportsbooks shade the lines that they can sell better. This often leads to the odds on favorites and overs gradually reducing, as more bettors stake these wagers and the sportsbooks can make better business if these lines have a higher edge.

Of course, external impacts can change the line movements drastically – like a coach getting fired right before a game – but these are very rare. By tracing the historical line movements, you can identify outliers and get an idea of where they may be heading, so you can look for the ideal price and try to beat the CLV.

Good for: Predicting the trajectory of future line movements

EV+ Assessment

EV+ is connected with CLV betting. These metrics give you a rough idea of how well the odds are priced against the expected probability of the bets winning. A powerful betting tool with a precise configuration can give you accurate EV+ valuations, and this helps you to figure out which prices are inflated and which ones are generously priced.

If you find odds that are very well priced based on the EV, there is a good chance these will slowly diminish in time, as the books want to shut out any offers that give you too much of an edge. On the flip side of the coin, odds with very poor EV valuations tend to go up as the markets converge, as sportsbooks need to keep a balance between the odds on either side of their lines. A good EV betting tool can give you these insights, helping you to beat the CLV, and even form hedged betting strategies.

Good for: Analyzing current lines vs expected value

Alerts and Notifications

You aren’t going to sit at your desktop or keep your mobile app open all the time, and even if you do, you would need to monitor the odds for hours on end to pick out golden opportunities. The best CLV betting tools set you up with custom notifications and alert options. You simply set a notification when the odds reach your desired price, and then the betting tool will send you a push notification if they ever get there.

The quality of the alerts really depends on how quickly your odds comparison tool scans fresh prices. The top betting tools often show the scanning speeds of their odds aggregators, and we found tools that can get fresh odds in a matter of milliseconds.

Good for: Taking advantage of favorable odds swiftly

Bet Tracking and CLV Beating %

These are retrospective features, that look back at the bets you have placed previously. They are important for numerous reasons, but perhaps most of all, to show you how well the betting tool has performed for you. A bet tracker will log all the bets you place and create data sheets with your win percentage, profit over time, and money spent.

The best bet trackers will also create charts so that you can compare the risk levels of your bets, the EV on your wagers, and the CLV beating rates. The latter is a percentage based on the prices you picked against the closing line value. You want a positive CLV, as this means your chosen prices were better than the final closing prices. You got the longer odds, and didn’t lose money against the closing prices. A negative CLV means your odds were worse than the closing line, so you could have gotten a better price if you had waited for the CLV.

Comparing this data in retrospect gives you an idea of how well the tool predicts the CLV on your chosen wagers. If you have a negative CLV, then you may have to change your betting picks, strategy, or choose another betting tool.

Good For: Testing your betting tool and strategy

Picking Your Betting Tool

Your budget will play the biggest role in choosing which of the betting tools works best in your strategy. Closing Line Value detectors are, for the most part, highly sophisticated tools that will cost top dollar. The data that needs to be stored, and the backlog of historical line movements is taxing even for the most prolific tools out there. And the more sportsbooks, sports events, and betting markets your betting tool covers, the more expensive it will be.

But there are more affordable tools that provide basic CLV data, and remember you can also integrate the statistical analysis, devigged odds, and EV projections into your predictions. Having a bet tracker, preferably one with CLV data, is one of the most valuable tools out there, as it determines how well your strategy and your chosen betting tool work together.

If you can get a positive CLV, you are one step closer to turning a profit on your bets. Hitting good value is only good if you can win those bets, so you need to plan your wagers ahead and pick a tool that can guide you towards those much-desired wins.

Use Trials and Discounted Subscriptions

While a lot of these tools may cost top dollar, you can always test them out through our promo codes or links to get discounted first subscriptions or trials. You won’t need to fork out a lump sum to test the tools, and if you give those trial days, weeks, or first month a good run, you can get the results you need to determine whether it is the betting tool for you or not.
