Tracking Sharp Money
Sharp bettors are professional or highly skilled bettors who consistently beat the market. Their action often moves lines and creates value for other bettors who can identify and follow sharp money. This calculator helps you detect professional betting patterns.
Key Sharp Indicators
- Reverse Line Movement (RLM): When 70%+ of bets are on one side but the line moves the opposite direction. Books are respecting larger, sharper action on the other side.
- Money vs Bets Divergence: When % of money differs significantly from % of bets. Sharp bettors place larger wagers, so they represent more money than bet count would suggest.
- Steam Moves: Sudden 2+ point line moves across multiple sportsbooks simultaneously. Indicates coordinated sharp action hitting the market.
- Early Sharp Action: Lines that move immediately after opening, before public bets arrive, suggests sharp money establishing positions.
- Closing Line Value: Sharp bettors consistently get better numbers than closing line, which is the sharpest/most efficient line.
Example Analysis
Patriots open -7, currently -5.5. Public bets: 78% on Patriots. Money: 52% on Patriots.
Analysis: Line moving TOWARD underdog despite heavy public betting on favorite = Sharp money on underdog. Bet Jets +5.5.
Lakers/Warriors total opens 225, moves to 222 within 30 minutes across all books.
Analysis: Coordinated sharp action hitting the Under. Likely an injury, lineup change, or sharp model identifying value. Follow the Under.
How to Use This Intel
- Follow Sharps: When multiple indicators point to sharp action, consider betting that side
- Wait for Steam: If you detect early sharp action, wait to see if it triggers a steam move for confirmation
- Fade Public: When public is >70% on one side with no supporting line movement, consider fading
- Track Results: Monitor which sharp indicators work best for your sports/bet types
