About Us
Welcome to Arbworld.net. Launched in 2009, Arbworld began as a passionate hobby project with a simple mission: to build a genuinely helpful, data-driven tool for users interested in sports betting. Over the past 15+ years we have grown into an established, veteran resource in the betting community, dedicated to providing transparent, real-time market signals.
What Arbworld does
Arbworld is a sports-market monitoring and analytics platform. Its tables organize Betfair Exchange prices and matched-volume data so visitors can compare price movement and the distribution of trading activity across outcomes. It is an informational tool, not a bookmaker, betting service, or prediction provider.
How the market indicators are calculated
- Moneyway is the share of the market's matched volume attributed to an outcome. In football 1X2, the outcomes are home win (1), draw (X), and away win (2). A 60% share describes the distribution of matched volume, not a 60% probability of that result.
- Dropping Odds compares the stored opening price with the current price. A shorter current price is shown as a drop; a longer price is shown as a drift. Movement describes a price change and does not by itself explain why it happened.
- Combined Score combines the probability shift implied by a shorter price, that outcome's Moneyway share, and total matched volume:
(1 / current odds − 1 / opening odds) × Moneyway share (%) × log10(max(total matched volume, 1) + 1). It is zero when the odds have not shortened. The score ranks a combined market signal; it is not a win probability, expected return, or profit estimate.
These indicators are calculated from the market values available to Arbworld and update when new data is received. Delays, limited liquidity, public sentiment, and later information can affect what the figures show. They do not identify the motives or skill of individual traders, and they should not be treated as evidence that an outcome is certain or profitable.
History and editorial approach
Arbworld launched in 2009 as a hobby project and has continued to develop its market tables and tools. The aim is to make the underlying price and volume signals easier to inspect, explain their limitations, and avoid presenting a market indicator as a guaranteed betting result.
