Strip the sportsbook's margin out of any market and see the no-vig fair price for each side. Uses the same power method we use across our feeds. The implied probabilities of every side add up to more than 100% because of the vig. Devigging rescales them back to 100% so you get a fair line. Use that fair price as the baseline for +EV math against a different book. Learn more.
A devigged price is your fair line. Use it as the baseline for +EV math: compare it against the price at a different book and see if there is edge. The power method works on most balanced markets; very lopsided lines can need a different model. Our live +EV feed runs devigging across every market for you in real time.
