Identify Betting Arbs in Betfair’s Related Markets

Finding cross market value

If you trade events on Betfair with connected markets like Football, you can use Bet Angel’s unique ‘Markers’ feature to highlight prices from one market to another on your ladder screen, this enables you to quickly spot and take advantage of any Arbing opportunities you’d otherwise miss or see which of the connected markets is offering the better price for your entry or exit.

Football markets

For example, if you look at the Under 0.5 and 0-0 Correct Score market these are effectively the same market so should always move in sync due to Betfair using xmxm (cross-market, cross-matching) as bets placed in one will often get matched in the other by but every now again the prices do step out of line and differ and this gives you the opportunity of an Arb (risk free bet) or one of the markets might offer a better back/lay price.

If you look at the image below on the left is the correct score market and the ladder for the 0-0 score line, for illustration purposes on the right I’ve also displayed the under Over/Under 0.5 ladders. Now notice the ‘Markers’ highlighted in the back/lay columns on the 0-0 Correct Score ladder – they are displaying were the back and lay price of the Under 0.5 currently are so you can see quickly and easily if these step out of sync.

In that image there is no arbing opportunity, but you can see there is a better lay price available in the 0-0 market (odds of 24.0) than the Under 0.5 where the best lay price is 25.0.
Fast forward a little later an Arb opportunity did appear, as you can see from the ‘Markers’ on the 0-0 ladder you could back in the Under 0.5 market by taking the available back price of 20.0, then lay at 19.5 in the 0-0 CS market at the same time creating a risk free arb bet.

How this is achieved on Bet Angel

You can do this using any interconnected market and even on multiple interconnected markets if you want to get really creative, but to get you started here I’ve created the two files that are required to display markers on the correct score market from unders markets.

These files are not just limited to 0-0 and under 0.5 markets, once a goal is scored you can then use the same file on the under 1.5 market to display the markers on the Correct Score market of either the 1-0 or 0-1 ladders, depending on who scored, after a 2nd goal it could be applied to the under 2.5 market to display the back/lay prices from that market on either the 1-1, 2-0, or 0-2 ladders in the correct score and so on.

In the image below the match went 0-1 so the file has been applied to the over/under 1.5 market so is using markers to highlight were the back/lay odds for under 1.5 goals are from that market on the 0-1 ladder in the correct score market.

If you’d like to see whats shown above displayed on your ladder trading screen all the settings have already been created and saved, all you need to do is download and import the files straight into your Bet Angel from the following post on our forum.

If you are a football trader you might also be interested in displaying the predicted odds after a goal on your ladder trading screen, if so for full details on how to do that please see this blog
