How it works and what it does

The Outliers Tool is designed to help you identify betting opportunities by systematically scanning prices across a wide range of bookmakers. It aggregates real-time odds data from multiple sources and applies algorithms to detect outliers—prices that deviate significantly from the norm. These outliers are categorized into several types, Outlier, Overcomes Overround, LPM Arb and Lay Arb. By highlighting these discrepancies, the tool empowers users to spot potential edges in betting markets quickly and efficiently.

The tool also integrates exchange market data when available, allowing direct comparisons between traditional bookmaker prices and the odds on betting exchanges. This feature helps validate outliers by cross-referencing them against a benchmark of true market sentiment.

Market Selection

When you open the tool, you’ll have two options to choose from: Top Markets or Select Market. Choosing Top Markets will generate a list of the top 10 markets that best match your chosen filters. These filters allow you to refine results based on the outlier categories described above, as well as set parameters such as minimum and maximum overround, minimum number of bookmakers, and the option to exclude lay arbitrage opportunities.

Choosing Select Market gives you full control to search and select specific markets manually. You can filter by sport, competition, event, and market type, allowing you to focus on the exact opportunities that are most relevant to your analysis.

Outlier (yellow) – any price that stands alone above the rest of the market by at least one price.
Overcomes Overround (green) – any price that is better than the next best price by more than the overround (excluding all outliers).

LPM Arb (pink) – any price that is greater than the last price matched on Betfair Exchange (the price between the light blue and pink figures in the relevant column).

Lay Arb (red) – any price that is greater than the lay price on Betfair Exchange (figure in pink of the relevant column).
