Opening odds vs closing odds РContrary to popular belief, bookmakers or betting exchange platforms rarely begin a betting market at the optimal price for all conceivable outcomes, therefore opportunities for long-term profit will always exist. We at onehundredgamblers endeavor to provide the greatest betting exchange service  and are happy to provide some insight into these crucial betting principles. This article will explain why closing odds are (on average) more accurate than opening odds.

Opening odds vs closing odds - Everything you need to know about Opening and closing odds and how to bet to your advantage


Betting odds are an excellent predictor of how much money you should bet following a successful payout. They also show the likelihood of an event occurring. Betting odds are continuously subject to shifts and movements dependent on the current happenings of the game. When it comes to how accurate these odds are, it all depends on the individual calculating them. Today, we will look at opening odds and closing odds, and whether one provides a better picture of future outcomes. An result may be given incredibly low odds at one moment, but his entire probability may shift half an hour later due to unexpected occurrences that could not have been predicted. The point is that odds are continually changing, which implies they are vulnerable to fluctuations. When are the odds most correct, and when are they most profitable?

Opening Odds

The opening odds are those that are available before the game begins. As you might expect, these chances are simply speculative – albeit cautious guesswork. They are normally accessible a few days before a game, and their accuracy is depending on the bookie’s expertise. elements that important include how thoroughly they conduct research and analysis, if they take into account all relevant elements, how precise their estimates are, and so on. They are based on existing data on aspects that are unlikely to change, such as recent form, injuries, playing style, line-ups, and so on. They are essentially the odds when the bookmaker opens the market for a future event. Bettor activity is another major component that contributes to the motions. The opening odds will fluctuate depending on how many people bet on that particular selection.

Closing Odds

Closing odds, on the other hand, are those available immediately before the event begins. Closing odds are more accurate when all factors are included. This is because more accurate information about the contest will be available. Weather information, changes in lineups, new injuries, the team’s current form, their current position, and how desperately they need to win would all be available. Could winning this match affect anything, such as their table position? Is it just another filler match in which winning isn’t critical to their overall success? Closing chances take into account all publicly available information, which explains why they are more exact.

Which of the two, however, is more profitable?

Short answer: If you know what you’re doing, both opening and closing odds can be profitable. You must always look for value, regardless of when you place your bets. A punter should constantly try to obtain an advantage over the bookmaker. Because opening odds are always changing, there is a danger that the odds will not always reflect the most likely outcome of the game. However, with closing odds, you are making a more informed selection that will lead to success because of the amount of data and statistics that are currently available. Overall, your pay-outs are determined by your skill as a punter.

How do bookmakers start a betting market?

Bookmakers set the odds for an event based on a variety of criteria including statistics, injuries, historical performances, and the amount of money anticipated to be wagered. They always include a margin on each odds. The bookmaker’s goal is to accept bets on the outcome in the best proportions feasible, ensuring a profit regardless of the outcome.

If you take a hard look at your favorite sports and all of the matches that have already taken place this year, you will see that opening odds are almost never a perfect depiction of genuine probability. Sport is not science, which is why many bookmakers place a 10% or higher margin on the odds in order to protect themselves from clever punters. A common example is when you can wager on an NBA game with Over/Under odds of 1.90/1.90.

Why are closing odds more accurate than opening odds most of the time?

The efficient-market hypothesis states that asset prices reflect all available information in financial economics, and if we apply this theory to sports betting or sports trading, it means that the sharpest bettors always place bets as soon as they see value, based on all relevant information they have, such as key player injuries, overall motivation of the team, and general attitude during practice. And, because they are the most astute bettors, they frequently place their wagers very early, often just a few minutes after bookies open the odds. And as more money is wagered, the odds will shift to a more accurate price.

Naturally, the closer we go to the commencement of a match, the more money has been wagered on it, and the more likely all inefficiencies have been eradicated. As a result, the odds at the commencement of the match (close line) will represent all of the information available in the market.

Opening Odds vs. Closing Odds

We can examine opening odds vs closing odds in the onehundredgamblers picks. I’ll explain the distinction between them here.

All of the historical odds on the onehundredgamblers site are provided by Pinnacle, which is why I frequently mention them.

Pinnacle employs their own market model to provide their own set of odds.

Based on books I’ve read, articles on the internet, and comments on related websites, I believe Pinnacle follows the following process:

  1. Based on their model for that league, the model manager generates a set of odds for the next fixtures.
  2. The model manager for that league compares his odds to any other sites’ odds at the time. He may then modify the odds up or down. The odds are then posted on the Pinnacle website, albeit with minimal restrictions. These are known as the “opening odds”. The odds for large tournaments may be given many days in advance, but the odds for lesser leagues, such as the Hungarian or Romanian leagues, may be released less than 48 hours in advance.
  3. If they notice any bets that are greater than typical, they assume their odds are excessively high and lower them. If no one bets, the odds become excessively low and are increased. The model manager for that league will also monitor the odds at other bookmakers to see how they are changing. Pinnacle’s goal is to have the most competitive bookmaker odds and a 2% bookmaker margin, hence they are highly sensitive to market price swings.
  4. Once the model manager is satisfied that his odds are correct and adjusted to the overall odds market, the stake sizes allowed on the odds will be increased, allowing larger bets to be placed.
  5. The closing odds are the last odds available right before kickoff.

The “opening” odds are provided for the onehundredgamblers picks that are released 48 hours in advance. These are Pinnacle’s opening odds, not the odds 48 hours before kickoff. If those odds were opened several days ago, those are the “opening odds” that onehundredgamblers will likewise show.

onehundredgamblers claims that their recommended minimum odds are simply that, “recommended,” and that profitable tactics on the site earn from betting on all odds, whether they are under or over the minimum recommended odds. Users wager on numerous websites, and they may believe that by removing picks with lower Pinnacle odds from the results, they will appear to be cherry choosing the best odds from their tactics, making the strategies appear more profitable than they are.

The strong suggestion not to bet on odds less than the minimum is based on my personal results in February, March, and April when those bets earned bigger gains.

Prior to this, I was betting on all odds, whether they were greater than or less than the minimum.

The basic idea behind the onehundredgamblers system is that we are not constructing our own market model, but rather looking for consistent inefficiencies in the Pinnacle model. If we can identify long-term patterns in which the Pinnacle opening odds were incorrect (too high), we can ride those faults until they are corrected, if they are ever corrected. Some errors, I believe, can be corrected, while others, I believe, are more difficult to locate. In general, the betting odds of underdog home teams appear to offer value, and this is where home strategies, home DNBs, and 1XDCs excel.

As a result, it is acceptable that the onehundredgamblers site publishes all of the odds. If those tactics indicate a profit by tracking odds that moved down as well as up after they were opened, we have the option of betting on all picks or skipping those that fall below the minimum.


I hope that clarified things a little when it comes to opening odds vs closing odds. The opening odds are Pinnacle’s market model’s first odds, which we use as a guide to determine if those fixtures’ odds are likely to be correct or incorrect and provide a value bet.

Because the opening odds are frequently changing and not available close to kick-off, onehundredgamblers calculates the P/L of the strategies using the closing odds, which should be more feasible for all users.
