What to check before betting on this pair
- Both books’ settlement rules for the market: overtime, walkovers, how kills are counted. The same market name does not mean the same rules.
- The account currencies differ (RUB and USD): the exchange rate affects the ROI.
- The age of both prices in the scanner card: with a median life of 4.0 s, a surebet with a stale leg has most likely closed already.
