Frequently Asked Questions
Why are live arbitrage windows so short?
Live odds update after every play. A price discrepancy usually lasts only seconds before one book catches up, so live arbs require fast execution.
Do I need accounts at multiple books?
Yes. Arbitrage requires betting each side at the book offering the best price, so you need funded accounts at every book you want to compare.
Is live arbitrage risky?
The main risk is execution: if you get one leg down and the other line moves before you place it, you are left with an unhedged position rather than a locked profit.
