The most common question I get is: how do you actually find these opportunities? The honest answer is: you can't do this manually. By the time you open two different sportsbook apps, compare the lines yourself, do the math, and go back to place both bets, the window is already gone. Books correct these gaps fast. Especially during live games where lines move every few seconds. This is the entire reason I use the @OddsJam Arbitrage Tool. It runs 24 hours a day, 7 days a week, scanning every major sportsbook simultaneously in real time. The moment any market becomes "crossed" — meaning the gap between books is large enough to guarantee profit on both sides — OddsJam flags it instantly. You see exactly which two books to use. 
You see exactly which side to bet at each book. 
You see exactly how much to put on each side. 
You see exactly how much profit you lock in before you've placed a single dollar. No math. No monitoring. No guesswork. There are two types of arbs to know about. Pre-game arbs typically run 2-5% ROI per play and stay open a little longer before the market corrects. These are great when you're starting out and want more time to execute. Live in-game arbs move faster but run 5-15% ROI and there are hundreds of them every single night. This is where the volume is. This is where the real money is made. The more books you have funded, the more arbs you can catch. The more arbs you catch, the faster everything compounds. OddsJam does 100% of the work. You just execute.
