Sports Betting Course – Over/Under Goals – Product Specifics


Fundamentals of Sports Betting (Betting on Over/Under ‘X’ Goals) is unlike any other book you will find elsewhere. It contains insights into how mathematics and statistics are applied to bookmaking, information that is rarely (if at all) found in the public domain.

Have you ever wondered how bookmakers set their odds? They must be pretty good at it to remain trading in a high risk industry built on small margins!

It is common knowledge that the gambling industry as a whole relies to a large extent on the ignorance of its customers and, only by understanding how bookmakers think and act, will you ever be able to compete with them on a level playing field.

The Most Valuable Book About Betting You Will Ever Buy!

This course is designed to give you the essential, fundamental knowledge necessary to understand odds calculation and the bookmaker market.

It deals with relatively simple descriptive statistics and teaches you how to look at data sets, calculate your own probabilities and odds, analyse the market odds on offer, and make informed decisions when predicting football results.

Amongst the topics you will work through are distributions, deviations, graphs and charts, odds calculation, financial terminologies, risk management, and of course, how to identify ‘value’ in the betting market.

You will gain a deep understanding of the many different elements required to understand the bookmaker market and odds calculation. Many false beliefs that the majority of gamblers and fans of football have about betting will be exposed and stripped away.

Readers will also be enlightened to learn about how odds are set in the market, where to find ‘errors’ in market prices, how to evaluate data and graphs, and much, much more.

What Do You Get For The Money?

The course comes in electronic format and the bundle includes the course book (PDF*) and a Bundesliga cluster table (Excel) for studying. This course employs a didactic method of teaching, which is an educational technique. It is a very structured style of learning and as such, each section of the course should be mastered before moving on to the next.

To further encourage you to learn, there is a plethora of exercises to practice what you have learned, and the solutions to the exercises are found at the end of the book, sometimes embellished with further explanations.

All of the course lessons are presented in a pragmatic, easy-to-follow, step-by-step fashion, with no more than passing respect towards the sport of football and the passion of its fans. After all, this book has been written by a lady who loves maths but dislikes football…!

In addition, you will receive the very latest Bundesliga table for the current season, so that you can put into practice what you have learned and within the course, you will find a discount code enabling you to download for free the German Bundesliga sheet in future seasons, meaning that you will always have access to the most current Bundesliga cluster table, forever: it doesn’t matter when you bought the course.

*By the way, the PDF is a professionally formatted document and if you have a double-sided printer you can print your own book for studying.

    Hi Soccerwidow,

    Me again, sorry. I wondering if there’s a mistake in the book or if I’ve miscalculated somewhere. It’s only a small difference, but I wanted to be sure I’m on the right track.

    On page 89, for (G) (i) we have to calculate the probability of winning a bet for ‘Over 2.5 Goals’ using the Five Seasons Method compared to the Value Calculator Method. You’ve provided Zero Odds for both. Zero Odds for the Five Seasons Methods are 1.60. While Zero Odds for the Value Calculator method are 1.43.

    So, to calculate the probabilities, I went…

    Five seasons. Probability = 1 divided by betting odds
    = 1 / 1.60
    = 0.625
    = 62.50%

    Value Calculator. Probability = 1 divided by betting odds
    = 1 / 1.43
    = 0.6993
    =69.93%

    But in the answers (on page 146), it says the respective probabilities are…

    Five seasons method: 62.36%
    Value Calculator method: 69.89%.

    Have I made a mistake somewhere?

    Kind regards,

      Hi Audiend,

      Please remember how to calculate ‘Zero’ odds…

      (1) Calculate the probability
      (2) Convert the probability in odds

      Not the other way round!

      Five seasons method expected ‘Zero’ probability: 62.36%
      1 divided by 0.6236 = 1.603592046 (rounded: 1.60)

      Value Calculator method expected ‘Zero’ probability: 69.89%.
      1 divided by 0.6989 = 1.43081986 (rounded: 1.43)

        Hi Soccerwidow,

        Thanks for that. I understand where I went wrong. All that was written, in the question, I’d forgotten that we’d already carried those calculations earlier. And it makes sense how a statistical probability is a more precise representation than the betting odds. As such, I understand what you mean by the idea of calculating the probability first and, then, converting it into odds.

        Kind regards,

    Hi Soccerwidow,

    Another question, sorry 🙁

    On page 72, exercise (D) asks me to ‘Calculate the game between Hannover and Dortmund using the Value Calculator Method and compare its suggested odds with the highest market odds.’

    But, again, where do I source the relevant stats for the value calculator then? Thanks for your help last time. I figured out that the accompanying spreadsheet enables me to switch between Bundesliga teams to generate those stats (and then simply go back and substitute the relevant data). But, as far as I can tell, that spreadsheet is only suitable for the last 5 seasons approach. I can’t find the snapshot of the value calculator for these two teams.

    Kind regards,

    Audiendi

      Hi Audiendi,

      Sorry for that confusion. You are making me aware that I put too much information into the course and packed it full with knowledge that is very obvious to me but not necessarily for the reader. I will take that into consideration once I start reviewing the course. I’ll have to extend on the explanations!

      Regarding your question… Data is always football-data.co.uk; there is no other source of free and reliable data available on the Internet. To help people with the Value Calculator here’s a video: How to prepare data for easy copying and pasting into the Value Calculator.

      Hope that helps. 🙂

        Hi Soccerwidow,

        That’s okay! Actually, (I feel a bit guilty saying this), I’ve watched that video before and have learnt how to use the Value Calculator (although I’m not betting until I finish the course). I’d just forgotten how to use it and I wasn’t sure if the 25 match results were included in the accompanying spreadsheets.

        I probably shouldn’t have troubled you over such a trivial thing, given I could have figured out the answer with extra effort. Anyway, slowly but surely we get through the course. I’m nearly at the halfway point.

        Kind regards,

        Audiendi

    Hi Soccerwidow,

    I’ve slowly been doing this course. I want to say a big thank you, I think I have learnt a lot.

    Just one thing is annoying me no end. On p: 62, you write

    ‘… we need to calculate and to make it as easy as possible, with the knowledge that calculating everything exactly is virtually impossible and unnecessary, we will therefore use the %CV of the entire Bundesliga to calculate matches of individual teams.

    Then, with respect to the correction factor for the Value Calculator, on p:68, you write:

    ‘… looking at the contribution of the 13 ever-present teams over the five seasons, the illustration [of the distributions of the respective goal differences] became more chaotic.

    Therefore, the “regression towards the means” is definitely not the distribution of the whole league.

    The “correction factor” is the H2H games!’

    I realise that you’re talking about different ways of calculating odds. Nevertheless, it does seem to be a bit of a contradiction to me.

    How do you reconcile the notion of studying the standard deviation around the mean (the expected value) for the entire Bundesliga as the best way of determining the range of fair odds with the notion that the entire league’s distribution is too vague and chaotic to be a precise correction factor?

    Sorry if I’ve misunderstood something along the way or if I’m simply confusing different concepts. I certainly don’t wish to seem rude. I’m extremely grateful as I’ve learnt HEAPS from this. This particular question just has me SO baffled.

    Hope you’re well, Soccerwidow.

    Kind regards,

    Audiendi

      Typo…

      [of the distributions of X Goals scored for the respective teams]*

      Sorry about that. I did not intentionally misrepresent what you are teaching us.

        Hi Audiendi,

        The chapter you are currently in, teaches the calculation of ‘Zero’ Odds/ Fair Odds. There are many roads that lead to Rome and the same applies to calculating odds: There are many methods to estimate the possible future result. Therefore, please continue with the course and you will see that many questions that arise at the beginning are explained later when the various puzzle pieces start falling together.

        The course teaches two concepts… one using 5 seasons’ data under the assumption that the performances of teams that have been playing for consecutive 5 seasons in the same league don’t change overnight (Cluster Tables) and the Value Calculator, a tool that calculates matches with teams involved that haven’t played for 5 consecutive seasons in the same league, but often enough to have a few H2H results available as correction factor.

        Of course, these two tools lead to slightly different results, but as mentioned in the course many times: From a statistical perspective, football matches do not occur frequently enough and the margin of error is therefore always going to be relatively large.

        Once you reach chapter 7. (p.116+) you will compare both, Cluster Tables and Value Calculator and see, that both reach similar but different conclusions.

        As mentioned in chapter 1.4. (p. 28+) – High (good) trueness of the mean is achievable, but not high precision. Nobody can calculate totally exact, not even the bookmakers…

        U 2.5 goals results vs implied probabilities (odds)

        The above graph shows the distribution of Under 2.5 results in comparison with the odds (implied probabilities). Despite the bookmakers pricing their odds close to the true odds the really observed results are still zig-zagging around the implied probabilities of the odds.

        I hope this helps to answer your question.

        Best wishes,
        Soccerwidow

          Hi Soccerwidow,

          Thanks for the considered and informative response. I guess it will start to make sense further down the track.

          Another question, sorry.

          On page 71, question B asks me to ‘calculate the odds for the Hannover vs Dortmund game (as in Fig. 27) for all ‘Under/Over X Goals’ bets using the statistics of the last five seasons.

          But where am I supposed to source the statistics? Have we gone over those teams already in the course and I’ve simply forgotten?

          Sorry to be a pest.

          Kind regards,

          Audiendi

            Hi Audiendi,

            To answer that question in the exercise you will have to return to chapter 2.3.3. (p.58+) and redo all the example calculations, but with Hannover & Dortmund (instead of M’gladbach & Hamburg).

            You’re not a pest! Don’t worry. Learning is hard, and I certainly prefer learners that ask questions to those who give up too easily. 😉

    Hi,

    I backtested this strategy for the last seasons of EPL and Bundesliga 1, but both returned -EV, EPL – 90 EURO with 10 euro stakes and Bundesliga -10 euro with 10 stakes.
    A total 139 bets were made, where I found value based on the calculated fair odds and the best odds available at the market for that match.

    Do you have the results for the last seasons of EPL and Bundesliga 1 ? Am I doing something wrong?

    • Soccerwidow
      23 November 2017 at 10:43 am #

      Hi Sarkec,

      no, you are not doing anything wrong. The only thing I would suggest is to leave the EPL alone. They don’t play as nicely ‘statistically correct’ as the Germans.

      The main problem with betting is that even if you consistently bet with a mathematical advantage on your site, the result distribution is random. That means that everybody will be experiencing different P/L curves if they don’t chose exactly incidentally the same bets.

      I’ve had a similar question to yours on another article and as reply I produced a P/L simulation. Just have a look at this: http://www.soccerwidow.com/football-gambling/betting-knowledge/value-betting-academy/simple-steps-win-over-under-betting/#comment-19567

    Hello. Thank you for the reply. I imagine that the work that goes into the books and articles is considerable so if it happens, great, if not…that’s life.

    I read the article and using auto translate and got the basic facts and seems interesting I will be testing this out over the next couple of weeks on the exchange. If it works (of course not every time but consistently) it could be a great tool for pre-match trading either to get a few free ticks or create free bets, either option seems very interesting.

    I hope you find the time to translate the update for the Over/Under course to English. I think that the course is very good and would really like to see more of it.

    Good luck with everything.

    Hello. I bought the book a couple of months ago, went over it, did all the exercises. First of all I should say that I had some small prior experience with statistics but I knew very little about excel. The book is very interesting and as far as I was concerned it is not a hard read, and English is not my first language. After finishing the book I created a small version of a value calculator just for overs and unders as well as working with cluster tables and started testing.

    I soon found out that back-testing would be hard for me because I have very limited access to bookmakers and have to rely on the exchange. That is why I am just writing now, because I needed some time to have at least a reasonable number of matches to form an opinion. My results so far are very interesting. I work with two probability clusters for the value calculator picks as well as using the ratio mentioned in the book for selection purposes.

    The first probability cluster is >75, of course if there is value in the bet. As you can imagine the strike rate is high, losing streaks low and bank has shown consistent growth with 150 bets so far. The second cluster is >50<70 probability. Here the results have been less consistent, but still profitable after 117 bets. I should say I am using very very small stakes. It does take time, I am building my own database for results and head-to-head data for every championship that I get involved in. I also keep track of every bet I make including probabilities, final results, true odds, and exchange odds so that I can later try to identify ways to improve the selection process.

    Using the clusters I do not have enough to form an opinion yet but the seem really promising. All in all the book is worth the money in my opinion. I look forward to the new book concerning 1 X 2 betting, if you actually have time to finish it.

    I had one question. So far I just went for set and forget type of bets so no trading in play. What we calculate are true odds before the game starts. If i wait in-play for the odds on the 1.5 market, for example, to reach a point where they were value at the start of the game, is that bet viable?

    Thank you very much for all your materials, I found them all very informative. Good luck with your future content and all the best.

      Hi Vlad,

      the odds in-play will go up to the expected odds; the problem is that there may be a goal the very first minute and you may not get your match. However, what you may consider, as you are interested in trading, is, to carry out the calculations one week (or at least a few days) before kick-off and then watch the odds moving in the direction of the calculated odds ranges within the last few hours before the match starts.

      Sometimes they reach the calculated range before kick-off but quite often they will only move by a few ticks. However, they will still move in the expected direction. Have a look at this.

      Coincidentally, I have just written an article on this topic. Unfortunately for Soccerwidow readers, it’s in German: Tipp für Trading: So werden Trades Smarter Simply run an auto translation over it. It should be understandable; I tried to write in as short sentences as possible.

      With the 1×2 book English readers will have to wait a little longer. As my mother tongue and education is German, I feel much more comfortable writing in German. Sorry! The Over/Under course is currently undergoing a massive update in German (for example, a large chapter on trading has been added – above article is a part from the update). We’ll see if we get anywhere with crowdfunding to get the book in the book shops and, if the book sells well, then there will be an English translation following.

      I truly hope that I will find the time to write the long promised book on 1×2 betting next year!
