OddStorm Review: Tried and Tested (but is it Recommended?)

In this article, we will be doing a detailed review of OddStorm, one of the oldest players in the sports arbitrage betting scene.

OddStorm were one of the earlier companies to develop a publicly available arbitrage betting software, and they continue to provide that same software (albeit upgraded along the way) to this very day.

They cover a large number of bookmakers and include regular, negative and Polish middles as part of their software. They claim to have the fastest surebet finder available, with a 1 second refresh rate for in play arbs on their Windows application.

However, they also have the highest subscription fees of any arbitrage betting software I have seen.

So what sets them apart? What allows them to charge such high fees? And are they worth it?

Let’s find out in this comprehensive OddStorm review!

What are the Most Important Factors When Choosing Arbitrage Betting Software?

Here are the most important things to look out for when choosing the best sports arbitrage betting software for you!


There's no getting around it - arbitrage betting software can be very expensive!

Premium software can cost upwards of €100/month, so if you are only planning on making a couple of arbitrage bets here and there, it is unlikely that you will even be able to recover the cost of the software!

Consider how much time and starting capital you have to invest in arbitrage betting before deciding on a software package.

How many sports does it cover?

Some arb finders cover as few as 5 sports, while others cover as many as 35! No prizes for guessing which one produces more arbs for their customers…

Note, however, that the vast majority of arbs are produced by the world’s most popular 5-10 sports, so having loads of sports is not always that much of an advantage.

How many bookmakers does it cover?

This is an important one. More bookmakers means more arbs, more profitable arbs (more likely to find better odds with more bookmakers) but most importantly, more options for you to sign up to if and when your accounts eventually start getting limited.

More potential bookmakers means a longer career in sports arbitrage betting.

How quickly does the arb feed refresh?

Many arbitrage bets disappear within a few minutes of being discovered by the software packages. This means that it is imperative that you are getting access to the arbitrage betting opportunities as they are being discovered.

Integrated betting calculator

The arbitrage software should include a built in betting calculator that automatically calculates the necessary stakes for each leg of the arbitrage bet to ensure that you lock in the profit.

Ideally, they should include options for rounding your stakes to avoid suspicion with the bookmakers as well as biasing your stakes to favour a particular outcome that you believe has value.

Standard and advanced arb types

A good arbitrage betting software will include middles (negative and even Polish) as well as cross-market arbitrage bets.

These advanced arb types tend to last longer and be less easily detected by the bookmakers than standard arbs, so I highly recommend that you get software that can find them.

Defensive arbing features

As we have discussed many times, having your accounts limited or closed is one of the greatest risks for an arbitrage bettor. Some arbitrage betting software now have features to hide your arbitrage activity.

This can include separate dedicated web browsers only for betting (to stop the bookmakers tracking you via social media and other trackers) as well as automatic cookie and cache clearing at the start and end of each betting session.

Having these features will again prolong your career as an arbitrage bettor, so they are definitely worthwhile having.

Now that you know what you should be looking for in your arbitrage betting software, let's get straight into the OddStorm review!

OddStorm Review - How does it Stack Up?

Oddstorm fares reasonably well on the criteria discussed above.


Price (per month)


Interface/ Speed


Arb Types




Here are the main pros and cons of the OddStorm software.

  • Access to over 70 bookmakers
  • Very high number of arbs found
  • Regular, negative and Polish middles included
  • Lightning fast arb feed refresh rates
  • Browser and desktop application
  • Very expensive
  • Outdated interface
  • Betting calculator functionality limited

Layout and Interface

The OddStorm interface is fairly straightforward and uncomplicated. Potential arbitrage bets are displayed along the left, and once you click on them, the details are displayed on the right.

OddStorm Review

The summary for each arb on the left lists the following:

  • Match details (including start time and date)
  • Profit margin
  • Betting market
  • A selection of the bookmakers with the best odds for each leg
  • An indication of what percentage of your total stake will be laid on each leg

Clicking on any of these opens up the arb details in the panel on the right.

Bookmaker Odds Comparison

In my opinion, the way in which the various bookmaker odds are displayed and compared is a key part of any arbitrage software.

When the odds are displayed in a simple, easily understood manner it is clear:

  • What order you should place your bets in
  • What your backup options are if a particular bet is rejected
  • Whether you can still form an arbitrage opportunity even if one bet is rejected
  • How safe it is to pursue that particular arb

I think many people overlook the importance of this when choosing their arbitrage software.

When you are actually arbitrage betting with your own money, you need to be able to place a number of high stake bets in quick succession without making any mistakes with regards to the match (including time and location), teams/players, betting market, bookmakers and stakes.

Any mistakes here can be extremely costly.

Sports Stadium

I find the display of the bookmaker odds in OddStorm slightly inferior to RebelBetting for example, because it is not clear what the profit margin of the arb will be if you are only able to get the second best odds available.

For example, in the picture below, it is not clear to me what the profit margin will change to if I can’t use 1xBet to bet on the draw, but have to go with VBet instead.

OddStorm sure bet

The onus is on the user to make the necessary calculations.

However, the integrated betting calculator is located directly above the bookmaker odds display, so you can manually adjust the odds in the calculator and re-calculate the new profit margin.

This is fairly simple to do, but it can take a bit of time if you are doing these checks on each leg of every arb you are interested in betting on.

OddStorm claim to have one of the fast surebetting software available with a rapid refresh rate, but this is somewhat negated by the manual legwork you need to do before committing to an arbitrage bet.

At least OddStorm only display bookmaker odds that will constitute an arbitrage bet, so if you see only one bookmaker available for a particular leg, it is clear that without that bookmaker, the whole arb falls apart.

This is very valuable information when determining what order you will place your bets in.

Number of Arbs Found

OddStorm covers over 70 bookmakers, meaning that there are always plenty of arbitrage bets on offer.

In fact, out of the various arbitrage betting software that I simultaneously tested side by side, OddStorm had the most arbitrage bets available.

I am quite confident in saying that even if you have very restrictive filters, you will have no problem finding arbs with OddStorm.

This is great for new arbers with only a few bookmaker accounts and also experienced arbers that want to go after only a very selective type of arb (usually an arb type that they think will not be obvious to the bookmaker).

  • WillHill
  • Youwin

This is a very solid list of bookmakers that should be able to satisfy even the keenest of arbitrage bettors.


Lightning fast refresh rate

OddStorm pride themselves on having an arb feed with a very fast refresh rate. The prematch arb feed refreshes every 15 seconds, the browser InPlay arb feed refreshes every 3 seconds and the Windows InPlay arb feed refreshes once per second.

Arbitrage bets can appear and disappear very quickly (within a few minutes), so having a fast refresh rate is definitely an advantage and will give you more opportunities over your fellow arbers using different software.

Odds History

Clicking on individual bookmaker odds brings up a table with the odds history, which is a nice feature. It can give you a feel for the volatility in the odds (which usually increases as an event start time approaches).

A graphical form like BetOnValue would be a welcome addition here but the table does the job just fine.

OddStorm Odds History


There is also the ability to filter arbitrage bets based on how many legs they involve (can keep it simple with just 2 leg arbitrage bets), or by how many hours until the bet will be settled (keep your return on investment high by only betting on events that will settle shortly).

You can also filter and activate alarms for arbs based on profit margin.

OddStorm filters

As expected, bookmakers can be filtered by enabled, required, or disabled. Setting a bookmaker as ‘required’ will ensure only arbs with this bookmaker included are displayed.

This is useful if you have an excess of funds at one particular bookmaker, or are looking to complete the rollover requirements for a bonus.

Built-in Betting Calculator

As mentioned earlier, OddStorm includes an integrated betting calculator in their software.

It’s a fairly standard arbitrage betting calculator with no particular frills. There doesn’t seem to be any way to round your stakes or bias bets to a particular outcome, which is a shame.

Arb Types

A unique aspect to OddStorm is that they offer regular, negative and Polish arbitrage middles as part of their service (for no additional cost!). Middles are an excellent type of arb that can have a huge payoff.

They also last longer than regular arbs and are less likely to be detected by bookmakers as arbitrage activity (especially negative middles). They can even help improve your standing at a soft bookmaker where you have been on a winning streak.

Regular and negative middles have a huge payout when a specific condition is met and I like the way that OddStorm displays this exact condition beneath the summary for each middle.

OddStorm Middles

Polish middles are an interesting beast, and I recommend that you only try them if you have practised extensively with regular arbs and other middles.

Polish middles pay out when a particular condition is NOT met and likewise OddStorm displays this condition beneath the summary for each Polish middle.

OddStorm Polish Middles

To the left of each Polish middle, you can see the expected profit margin if the specific condition is NOT met.

In this example, you can expect to profit 92.50% (almost doubling your money), as long as the match does not end in a draw.

Most other top-tier arbitrage betting software include regular and negative middles, but few include Polish middles (they can be considered a form of gambling rather than surebetting so many arbers are not interested in them).

This is one way the OddStorm sets themselves apart from the other surebetting software.


OddStorm is available in the following languages:

  • English
  • Bulgarian
  • Czech
  • Swedish
  • Russian


Here’s the part you’re not going to like. OddStorm is the most expensive of any arbitrage betting software that I have seen on the market.

A single month’s subscription will set you back €150!

OddStorm price

The expensive price is the main drawback of the OddStorm software. It can be difficult to part with this much money if you are new to arbitrage betting and aren’t convinced that you’ll be able to at least recover your monthly subscription fee.

I recommend OddStorm only if you have a starting capital of €3,000 or more. Otherwise, you will be investing your time for little return.

OddStorm Review - Conclusion

OddStorm is a solid choice for an arbitrage betting software. It offers tons of arbitrage bets (thanks to extensive bookmaker and sport coverage), very fast odds refresh rates and all types of arbitrage middles.

It is, however, very expensive relative to the competition and comes with quite an outdated interface.

OddStorm really shines as a surebet finder for those who either would like to place a high number of arbitrage bets with many bookmakers, or those who want to be very selective about the arbs that they choose (and therefore need a large number of arbs from which to filter).

If you have plenty of starting capital and the price tag doesn’t put you off, I recommend OddStorm. Otherwise, Betslayer may be a more suitable budget friendly alternative (Betslayer will find much fewer arbs however).

I hope you have enjoyed my OddStorm review! If you have any more questions, please leave a comment below!
