Edge
Any advantage a bettor has over the bookmaker or casino on a specific wager.
An edge is any mathematical advantage you have on a bet. In casino games, the house always has the edge (the house edge). In sports betting, an edge means you've found a bet where the true probability of winning is higher than what the odds imply.
Edge can come from many sources: superior information, better models, exploiting slow-moving lines, taking advantage of promotions, or finding pricing mistakes. The key is that your edge must be large enough to overcome the vig.
Without an identifiable edge, you're gambling — not investing. Professional bettors can articulate exactly where their edge comes from for every wager they make.
