Quick start: using Arb Watcher

  1. Pick your books. On the arbs page, tap My books and choose the sportsbooks you have. Arbs, middles and +EV then only show bets you can place.
  2. Take an arb. Open one to see the stake on each side. Bet the off price first, check both bet slips, and use the calculator if a price moved.
  3. Check the picks. The model picks post once a day at 10 AM Eastern, the same for everyone, with a public record.
  4. Research a player. Player search shows his games against tonight's line, the model's chance, matchups and every book's price.
  5. Build a parlay. Tap + on any prop to add it to the bet slip, then price the whole parlay at one book.
