How to Maximise Your Closing Line Value

Maximizing Closing Line Value

In Part 1, we went over what CLV is and why it is crucial to understand for sports bettors. In Part 2 we’ll cover the practical actions you can take to actually improve it. Luckily, there isn’t a secret system here privy only to the sharp bettors. Most of the work is down to being disciplined and avoiding the bad habits that quietly drain your EV over time. Do that, and you’ll start seeing a noticeable improvement to your Closing Line Value.

Line shopping is your biggest advantage

It’s common for most beginner punters to bet at only one book out of either habit or convenience. This habit, however, costs them money on almost every bet.

Line shopping (comparing odds across multiple bookmakers before placing a bet) is the single most actionable thing you can do today to improve your CLV.

Let’s compare a two-way market where one bookmaker has a price of 1.80 for a bet, while the other has 1.90. Punter A shopped and was able to grab the bet at 1.90, thus giving him a CLV cushion of 5.6% over Punter B who took the same selection at 1.80. If the line closes at 1.70, Punter A will finish with a CLV of +11.8%, while Punter B will finish with +5.9%. Apply that across hundreds of bets a year and you will see a substantial difference in profit.

In order to line shop effectively, you’ll need to create accounts at multiple sports betting sites. Ideally as many books as you can manage. Each book you add to your roster will increase your likelihood of grabbing the best possible line for each bet you make.

Timing matters as much as the price you take

Now that we covered where you should bet, the next factor in maximising your CLV is knowing when to bet. This is where it gets a bit tricky. You’ll need to assess whether or not there is information that the market has not yet absorbed, or whether you are waiting for information that has not yet been released.

If you believe you have an early read on a match that the market will eventually catch up to, then you should bet early. For example, favourites tend to get shorter and shorter in price as kickoff approaches, this is especially true for heavily public-bet events like the World Cup and Super Bowl. In this scenario, if you are looking to bet on the favourite, you should do that earlier rather than later. In general, opening lines tend to be softer because everyone is working with less information. The oddsmakers have done their initial pricing and the sharp money has not yet arrived.

On the other hand, there are also situations where the edge you are targeting is reliant on something that has not yet been confirmed. This is often the case with factors such as injuries, starting lineups, weather, etc. In this scenario, it is usually beneficial to wait until the information comes in, and then place your bet. Betting with less information oftentimes means making educated guesses. The risk, of course, is that a high number of bad guesses can sink your CLV.

Reading sharp moves

Sharp money will almost always have an impact on line movement. If you can learn to read when the sharp money is coming in, you can use that to improve your CLV.

When respected bettors come in for a significant amount, the books adjust. This results in what is known as a ‘steam’ move, i.e. a sudden, rapid shift in the price of a bet at multiple bookmakers within a short window. When this happens, the bookmakers will swiftly adjust their odds in order to better cover themselves.

In a similar vein, reverse line movement is when the odds move in the opposite direction to where heavy public money is going. For example, take an NBA game where 80% of the bets are coming on the points total of Over 228. If the line then keeps drifting lower, say to 225, that is certainly something to take note of as it signals that sharp money is on the other side (the Under, in this case).

The tricky part is that when you see these types of moves, the value is usually gone.

You can’t reliably chase these numbers, because the books will have compensated and adjusted their odds. What you can do, however, and what these sharp moves are extremely useful for, is using them to judge your own reads. If you place your bet early and notice the line steamed down in price, then you made a good read!

The habits that erode your CLV

CLV, whether positive or negative, doesn’t happen in sudden, vast amounts. It’s accumulated over hundreds or thousands of bets over time. These are the primary habits that you will want to avoid:

Parlays and accumulators:

One of the most popular bets for punters is the parlay/accumulator. New bettors are drawn in by the promise of a huge payout, and even experienced bettors can fall into the trap from time to time. The problem here is that every selection you add to an accumulator compounds the house edge (vig). A four-leg parlay at a 5% margin per leg comes out to 18.55% margin on the whole ticket. To put it simply, you’re paying tax on each leg, and the match is firmly stacked against you more than the individual odds would suggest.

Same-game parlays:

SGPs have exploded in popularity in recent years. The disadvantages of regular parlays all still apply here, but it’s even worse in SGPs because you are paying an additional tax on legs that directly correlate.

Undisciplined in-play betting:

While not always the case, some bookmakers price wider vig on in-play bets in order to better protect themselves. On these books, you’ll have to be extremely disciplined with your in-play bets and avoid any impulsive bets. See more about how in-play betting works.

Not shopping around:

As we mentioned earlier, having accounts on multiple betting sites is vital to optimising your CLV. It’s fine to have books that you prefer, but intentionally placing a bet with worse odds on one site over another is a major CLV killer over time.

Chasing losses with varying stake size:

This is also a bankroll management problem, but it also directly ties into your CLV. Chasing losses by increasing your bet size, usually goes hand-in-hand with placing bets at worse prices. Even if you take a bad beat, try to avoid tilting and stick to your predetermined unit sizing.

Putting it all together: where the edge exists

If you begin line shopping and always seek the best price, you’ll instantly increase your CLV. Combine that with sensible bet-timing, learning how sharp money affects line movement, and avoiding -EV betting situations and you’ll continue to see your CLV gradually improve over time.

Remember, this will not happen in a week - it’s a long-term metric and stacks up over a large sample size of bets. Track your bets, the line movement, and what the price closes at. The market is sharp, there’s not denying that, but it’s not perfect! There are value bets available every day, across multiple sports and multiple leagues. It's your job to seek them out!
