  1. Hi, I’m just wondering if a portfolio made up of various systems selected properly as you explained may end up with an actual negative yield…did it ever happen to you?
    Thank you and congratulations for the great website!

    1. Hi Mark, although normally it shouldn’t you can never say never.

      Targetting the sweet point in the odds using the HDAFU Tables you are targetting low probabilities and I’m sure that you experienced in your life probably even more than once that, when you were throwing a dice (16.67% probability for a ‘1’, for example) that you had to wait for 20 (or even more) rounds until the first ‘1’ was thrown. It probably happened to you only once in your life but certainly not ‘never’. In that case, you may have experienced a ‘negative yield’ should you have included the ‘1’ in your portfolio of bets.

      Hope that makes sense.

  2. Hello again Jamie,

    I can’t teach you how to use Excel, but the cluster sizes are determined by Excel’s maximum number of 200 reference points for producing graphs.

    This is a limitation that has always been a barrier in Excel, thus we can only produce 200 “clusters” in any one table.

    To be honest, it doesn’t make much difference: 200 clusters is plenty, and you will see that some odds account for multiple numbers of clusters – e.g. draw odds of 3.40 might account for several clusters of their own, whilst odds of 1.06 to 1.10 might be contained in a single cluster.

    Even if you could change it in Excel, it wouldn’t make much difference – you are still able to fine tune the results by looking at the data tab to determine where the profitable ends of the inflection points graph start (see the User Guide).

    Be sure to read the comments in the Winter League summary, which also contain a mine of useful hints and tips.

  3. Hi,

    How do you pick the clusters that you want to use, is there a methodology behind it? I have purchased the Netherlands HDAFU tables but was wondering why they are set the way they are and the thinking behind it.

    1. Hi Jamie,

      I’m not sure what you are referring to precisely?

      Do you mean the Inflection Points graph itself, or choosing which systems to go with that are highlighted by the graph?

      1. I am referring to the cluster sizes. How do you set them or decide on them? How do you group them and work them out and could this be changed or would it matter?

  4. I can suggest to have a look at Sportmarket Pro. It’s a multiplatform broker like Vodds that includes exchanges like Betfair at 2.5% fixed commisison, Betdaq at 1.2% fixed commission and Matchbook at 1.8% fixed commission ON WINNING BETS only, instead of every bet (winning and losing) like betting on Matchbook website. They also have Pinnacle, SBOBET, and all the major asian bookies. I used them for almost a year now and they are very professional and fast in their withdrawals also. Definitely check it out!

  5. Hello again Tim,

    Well, one of our accounts is Smarkets, whose commission rate is 2%, so we do use exchanges ourselves.

    Of course, if you wish to use Betfair, then their 5% commission rate will certainly take a chunk of your profits away.

    However, the system should still work – it just won’t earn you as much profit…

    1. Hi Tim,

      When we began the 2016 Summer League campaign, we started off with £2,000 in various accounts.

      But the official bank size on paper was set arbitrarily at £1,500 to cope with the longest possible losing streak of any one system. Our analysis showed this was 15 losing bets in a row in the Japanese J-League away win strategy.

      I say ‘arbitrarily’ because we never expected to lose 15 bets in a row with all the systems overlapping and supporting one another.

      Thanks for your question.

  6. Hi! Congrats on articles!
    I have a tricky question: what happens if “a lot of users” start to use these methods at the same time, finding the same spots for an eventual profit? Wouldn’t these strategies start to become obsolete?

    Thanks!

    1. Hi Gabriel,

      Firstly, we are not giving away systems – merely the tools for individuals to decide upon their own strategies.

      As mentioned in the articles, everyone has their own levels of acceptable risk and, therefore, each person’s portfolio of chosen systems and bets will be different from the next person’s.

      Add to this the facts that each punter will be playing with different levels of stakes and have access to different sets of bookmaker and/or betting exchange accounts.

      Also, one person may not be as disciplined as another regarding the placement of every betting opportunity.

      Therefore, I would say that it is highly unlikely that you will see any noticeable betting patterns affecting the market as a result of any systems being followed by Soccerwidow readers.

  7. Right Winger,

    let’s suppose for a match on the HDAFU analysis two teams have the same odds. How do you ensure the correct calculations when the system have to count favourites and underdogs? How can Excel manage to understand which one is the real favourite? Maybe you just shorten one of the two by a 0.01 to achieve this purpose?

    1. Hello again Daniele,

      If you’re using Oddsportal to check the odds, and the highest odds are the same for both teams, use the Average Odds as a tie-break.

      Whichever team has the higher average odds, make them the underdog, and vice versa.

      I have never seen a match where the highest odds are the same as each other, and where the average odds are the same as each other.

      For the sake of the HDAFU tables, we do occasionally increase the underdog odds by one tick as you suggest, but this happens so rarely that it should not be a statistical concern at all.

      Hope this helps.

  8. Hi Right Winger!
    How do you split the seasons for the mid-season break? Some seasons have their holiday breaks before the official closing of the first round of games (for example, although this changed in this year, the Italian Serie A had their holiday break just before Christmas, until around a week in the beginning of January, but the first round of games was finishing only one week later. So how do you choose when to split the season in a case like this? Is it on the longer holiday break, making the two halfs slightly different in terms of length, or just the official end of the round?
    Thanks in advance for your reply

    1. Hi Daniel,

      Yes, it’s the holiday break – sometimes the two halves of a season do differ in length, but only by a few games and this is not likely to have much statistical significance on the results.

      We split wherever the ‘clean break’ is in the middle of a season.

  9. Hello Jo,

    Marathonbet and 1x2bet seem to be so similar in their odds setting that it is difficult to see that they are not connected in some way. There must be some common denominator connecting both bookmakers (apart from the fact they are both Russian).

    My advice regarding the fluctuations in prices between these two and the rest of the market is to trust the majority as your guide. If the indication of the majority is within your inflection points, but you can get a higher price with Marathonbet or 1x2bet, then place the bet at best price with either of these two.

    But be careful, we have experienced situations where, although the prices on their sites are indeed well above the crowd, stakes are sometimes limited.

    This is just a method of attracting ‘quick’ money to help them balance their books, which is essential practise for low margin bookmakers of this nature.

    I am preparing a paper on odds movements throughout the ante post market, which should be available later this year. It will be a vital addition to your knowledge.

  10. Hi Right winger,

    I encountered one problem with Marathonbet a few times and will probably have it in the future. The problem is: I check odds in the Oddsportal on the outcomes having potential to bet on, 1 hour before kick off time odds are quite above my top (or below) inflection point I have to bet on across all bookmakers Oddsportal provides. But less than an hour before kick off time odds dropped significantly across all bookmakers except Marathonbet. Odds provided by all remaining bookmakers dropped within my inflection points with an exception of Marathonbet (and sometimes 1xbet is also slow to follow the market). They lower their odds just 0.2 or so during the last hour, while others move their odds down 0.5-0.6 or so. And if odds at Marathonbet are 4.3 and the rest of the bookmakers have 3.8-3.9. I would say Marathonbet is quite off line and what confuses me the most, these odds are available in their site to bet on, so it’s not Oddsportal fault. If my inflection points are between 3-4 should I care about Marahonbet odds or remaining bookmaker odds considering are the odds within my inflection points or not?

  11. Just wondering what would happen next season in terms of updates, do you provide instructions on how to update the tables or would I be required to buy new updated tables?

    1. Hi Jamie,

      Updating the tables each season is a major task. You also need reliable historical odds representative of a certain period in time in order to use the tables most effectively.

      We also upgrade the tables each season with improvements or extra features.

      We are therefore sorry that we cannot provide a user manual for people to upgrade the tables themselves. Besides, in terms of the the time it would take to perform such an exercise, it is probably cheaper for our customers to buy the newest versions.

      The updated Winter League tables will be available in late May, early June, when the 2016-17 seasons have ended.

  12. Hi Right Winger!

    You said you use the highest closed odds. Its Ok, but my question is: Which bookmakers’ odds? Because on the page Oddsportal there are many soft and small bookmakers for example 1xbet, Marathonbet, Tempobet etc.. who give the highest odds on the market. Why?
    Because the are very slow and they can not follow quickly the oddsmoving.
    Also I would like to know, from which bookmakers odds do you choose when you make the HDAFU tables?

    Thank you!

    1. Hi Attila,

      Thanks for your comment.

      Yes, we use Oddsportal odds but we are also aware of the technical glitches they have.

      Indeed, all sites using API’s to record odds at specific times have problems.

      Certain bookmakers on Oddsportal do not update properly. This can create a situation where a firm’s opening odds never update and end up appearing as their closing odds too. They then stick out like a sore thumb in comparison to the closing odds of others around them.

      Because of this, Oddsportal highest odds at close of the ante post market need to be checked for accuracy. When recording them we use over-round calculations as an indicator of anything that needs to be double-checked.

      Getting accurate odds representative of any one moment in time during the ante post market is the biggest challenge for anyone when compiling data for analysis.

      We have no choice but to use Oddsportal’s compulsory set of 20 bookmakers or so, added to which, are another 10 of the larger, more reliable firms. Our personal portfolio is therefore around 30 bookmakers.

      Many of the problems are caused by Oddsportal’s compulsory list. Problem bookmakers here include Tempobet, Marathonbet, Titanbet, Boylesports, William Hill, to name but a few.

      Contrary to your point about odds moving slowly, I would disagree as no bookmaker wishes to remain with the highest odds on any outcome for any great length of time. They need to keep their books balanced and will dip in and out of the market according to the weight of money they receive from the punters.

      If any one bookmaker were to offer best price some way ahead of its rivals, then it would see a lot of money placed on that outcome as punters shop for the highest price. Receiving a flood of money on one outcome leads to more difficulty balancing the other outcomes.

      Low margin bookmakers (e.g. Pinnacle, Marathonbet) rarely offer best price on the favourites – more usual practice is bigger prices on the more unlikely outcomes.

      It is always educational to watch a site like Pinnacle and see how often their prices move – sometimes several times a minute on the more popular games. Compare this with betting exchanges where prices also fluctuate from minute to minute. Of course, betting exchange prices are influenced and led by the bookmaker prices – if this was not the case, we would all be rich, successful and professional arbitrageurs!
