Frequently Asked Questions
What is a sure bet (arbitrage)?
A sure bet, or arb, is when different bookmakers offer odds on the same event that create a guaranteed profit. By betting on all outcomes at the best available odds, you lock in a profit regardless of the result.
Is arbitrage betting legal?
Arbitrage itself is legal — you're simply placing bets at the best available odds. However, some bookmakers may restrict or close accounts that consistently exploit arbs. Always check the terms of each bookmaker.
How often are odds updated?
OddsFetcher updates every 5 minutes. Because odds shift frequently, especially near game time, always verify on the bookmaker's site before placing a bet.
What does the profit percentage mean?
The profit percentage shows how much you'd earn on top of your total stake. For example, a 5% arb means if you stake $100 total across all outcomes, you'd receive $105 back regardless of the result — a $5 guaranteed profit.
What's the minimum profit I should look for?
Most experienced arb bettors look for opportunities above 2-3%. Very small arbs (under 1%) may not be worth the effort after accounting for betting margins and the risk of odds changing before you place all bets.
What are 'hot' opportunities?
Hot opportunities are arbs with a profit percentage of 10% or more. These are rare and often disappear quickly as bookmakers adjust their odds.
Why did an opportunity disappear?
Odds change constantly as bookmakers adjust their lines and as other bettors place wagers. An arbitrage opportunity that existed 5 minutes ago may no longer exist when the odds are next updated.
Is OddsFetcher free?
Yes. The basic scanner is completely free. Premium features (email alerts, full stake calculator, historical tracking) will be available in the future.
How is the stake calculator calculated?
The stake calculator divides your total stake proportionally across each outcome based on the decimal odds, ensuring an equal profit regardless of which outcome wins.
Does OddsFetcher accept bets?
No. OddsFetcher is an odds comparison and arbitrage finding tool. We display odds for educational reference only and do not accept bets or process payments.
