What are the most common mistakes sports bettors make?



How to avoid the most common mistakes in betting

How important is the bookmaker you choose?

What impact do cognitive biases have on bettors?

 

 

While Betting Resources aims to educate bettors about everything from the basics of betting to predictive models, some bettors still fall into the common traps that inhibit success. This article provides a basic explanation of the common mistakes bettors make and how to avoid them. Read on to learn more.

Failing to understand the concept of value

Value isn’t as simple as finding a soccer team on a winning streak that is priced at high odds against a team that has lost a few games in a row.



Value is about understanding what betting odds represent, calculating your own probability estimation, converting it into odds and then looking for discrepancies in what you believe the odds should be and what the bookmaker believes.
One of the most common misconceptions in betting is that good bettors don’t lose. This simply isn’t true. Good bettors lose less often than they win
Bettors often make a mistake when determining what value is. It isn’t an opinion but rather the use of information, data, models (like expected goals) and historical results (handicap performance being one example) to form a more accurate prediction than the one provided by the bookmaker.
Once you know what value is, you can begin to calculate expected value for any bet you place - this is essentially a calculation that will tell you how much you can expect to win or lose if you were to place the same bet multiple times over.

Not choosing the right bookmaker

Bettors are given an endless supply of bookmakers they can choose from. Just like any other industry, there are different approaches to bookmaking and everyone will claim to be the best. However, it doesn’t take much to analyse your options and discover that some bookmakers offer a lot more than others.
Most bookmakers give away free bets and bonuses that appear to offer value. What a lot of bettors don’t know is that in order to provide these offers, bookmakers will increase their margins - something that ultimately impacts the odds you bet with.

While these kinds of bookmakers lure customers in with expensive marketing campaigns and false promises, they also don’t let bettors win. If you make a consistent profit betting with the kind of bookmaker that offers you free bets, your limits will be severely limited or your account will be completely closed.
Choosing a bookmaker because they offer you a free bet is a mistake bettors simply cannot afford to make - especially when Pinnacle offers the best value odds, lets you bet however much you want and doesn’t ban or restrict winners.

Not using a staking method

If you want to make a profit from betting you need to have an advantage over the bookmaker (this is referred to as an “edge”). An example of having an edge would be knowledge of team news in a soccer match, changes in the weather in an NFL game or any other potential influence on the outcome of a match that the bookmaker is unaware of.

Staking method
Method of calculating the appropriate amount of money to place on a bet for consistent profit making as part of a betting strategy.
Regardless of where your edge comes from it is made redundant if you don’t manage your money correctly. The use of staking methods is essential if you want to make money from betting and failing to do so is a mistake that can cost bettors dearly.

If you don’t manage your money when betting, you won’t have any money left to bet - it’s as simple as that. There’s nothing wrong with an “all in” approach, as long as you know not to expect it to result in consistent profits.

Not being aware of cognitive biases

It is natural to assume we control our thoughts and actions but those who are interested in psychology and behavioural economics will know there are certain “biases” that cause humans to deviate from what we would class as rational judgements.
Confirmation bias is one such bias that can be applied to betting - this is effectively being drawn to evidence that suggests the bet you are making is right whilst disregarding evidence that proves otherwise.
The use of staking methods is essential if you want to make money from betting and failing to do so is a mistake that can cost bettors dearly.
Anchoring is another bias that bettors may not be aware of. Anchoring, also known as focalism is the tendency to rely on the first piece of information offered - this could be very detrimental in betting as things can dramatically change in a short period of time.
This lack of objective thinking and logical reasoning can cloud judgement and lead to betting decisions that are based on opinion as opposed to critical thinking. Bettors may not be able to control cognitive biases but one of the biggest mistakes to make is failing to acknowledge them.

Being too concerned about losses

Loss aversion - a preference for avoiding losses instead of acquiring potential gains - is also prevalent in betting and is another cognitive bias that many bettors aren’t aware of.
One of the most common misconceptions in betting is that good bettors don’t lose. This simply isn’t true. Good bettors lose less often than they win and if they lose, they will use a staking method to ensure they don’t lose all of their bankroll.
The presence of randomness and luck in sports betting means even the most sophisticated models can sometimes be wrong. Thinking that you need to avoid losses at all costs is one mistake that bettors should certainly avoid.

Betting because it’s convenient

Even if bettors know what to do in order to succeed and avoid the common mistakes mentioned above, the element of convenience can still undo a lot of hard work. 
Of course, for those who bet for entertainment purposes, betting out of convenience doesn’t matter but if the aim is to make a profit, you should only bet when the time is right (when you have an edge and positive expected value).
The increase in popularity of curated bets, online betting and the emergence of mobile betting apps has made the process of placing a bet much easier than ever before and bettors who want to make money cannot afford to bet because it’s convenient.

Instead of betting on a soccer match because it’s on TV or an NFL game because your bookmaker has sent an app notification saying that they’ve increased the odds, stick to what you know, stay disciplined and remember you’re betting for long-term success, not short-term profit.

How bookmakers make money

Every bettor is looking for ways to beat the bookie. To become a consistently profitable bettor though, a deep understanding of odds calculation is only half of the story; the other half is knowing how bookmakers operate. In this article we lift the lid on the methods that keep both bookmakers and professional bettors profitable.

Making a book, in betting parlance, refers to laying bets on the outcomes of an event. The term originates from the practice of recording bets in a hard-bound ledger, giving the English language the term bookmaker.
Bookmakers have been around for thousands of years in one form or another. The role of bookmakers is similar to that of a stockbroker. They accept money from multiple people on various outcomes and after the event is finished they pay out the winners. In return for this service, they get a fee (known as the margin) and their goal is to make a profit.

The mathematics of bookmaking

Online betting companies employ a team of people, usually referred to as traders or odds compilers. Their job is to set the odds based on a mixture of statistical probabilities and public opinion with the aim to closely represent the chance of every outcome, plus the margin.
Accounting for all the variables in any event is not an easy job. For every match the traders have to account for the form of the squad, injuries of key players, the referee, influence of the crowd etc. By considering all the variables, they first calculate the real chance of an occurrence and then price in the margin.
Below are the Pinnacle’ odds for the match Leicester City vs. Norwich City on Saturday, 27th February.
OddsImplied Probability
Leicester City1.53165.32%
Draw6.81014.68%
Norwich4.54022.03%
If you add up the probabilities, you will notice that you get 102.3%, meaning that the bookmaker has a profit margin of 2.3%, assuming balanced action on all sides.
A match can be priced anywhere between 101% and 120% depending on the market and the betting activity. Premier League matches for example are typically priced up to around 104% according to Oddsportal.com
All strategic long-term bettors seek to maximize their returns by obtaining the highest odds possible. The higher the margins of a bookmaker, the poorer their odds offering is, as margins can affect your long-term profitability. Here's a short video on how to calculate the betting margin.
It is extremely important that you know the margins the bookmaker you bet with is offering. If they offer popular markets like the Premier League at greater than 104%, you are better off shopping around for a bookmaker with lower margin. For less popular leagues, markets of 110% or more are the norm.

Understanding odds fluctuation

Unlike the bettors, who try to predict the outcome of a match in order to make money, traders don't gamble. Their priority is to ensure that they get bets on the outcomes of all outcomes proportionally (commonly known as “balance the book”), so that they make a profit regardless of which outcome prevails.
Once the odds are published, the traders closely monitor the flow of the stakes and how they are distributed among the different outcomes. If the bets are placed according to the traders’ calculations, then the odds will remain stable. If, on the other hand, a disproportionally large amount of money is placed on one side of a bet, the odds will be recalculated.
Let's take the Leicester City vs. Norwich City match from above and assume that 100 bettors placed their $1 worth bets as follows:
OddsBets distribution
Leicester City1.53175%
Draw6.81010%
Norwich City4.54015%
If Leicester wins, the bookmaker will collect $100, but will have to pay out $75*1.531 = $114.825. In this case, the software used by the traders will start to indicate a loss and the odds will be readjusted.
These adjustments are continuous and performed by all bookmakers in an attempt to keep their books balanced. It is the fluctuation of odds that allows for arbitrage betting, also referred to as “sure bets”.

Consistent profit making

An arbitrage bet utilizes odds from across different bookmakers by placing bets on each of the option resulting in the aggregate margin in the bettor’s favour, hence producing a proportionate profit.
Pinnacle are widely regarded to offer margins as low as 1.5% for soccer and baseball and apply a low margin policy to all markets posted, with any of the widely available arbitrage softwares often highlightening Pinnacle on one side of an arbitrage.
Now that you know how bookmakers make money, you are one step ahead of the average bettor.

A must read for anyone who aspires to become a professional sports bettor.
