Core Capabilities

​
Expected Value (EV) Calculation

Line Gap calculates the expected value of every bet by comparing true probability against sportsbook odds: 
EV = (Probability × Payout) - (1 - Probability) × Stake
What Makes Our EV Calculations Unique:
1

Historical Data Analysis

We analyze ESPN game logs for the past 20 games to calculate true probabilities based on actual performance.
2

Recent Form Weighting

More weight is given to recent games (last 5) to account for current form and momentum.
3

Opponent Adjustments

Probabilities are adjusted based on opponent defensive ratings and historical matchups.
4

Home/Away Splits

Performance metrics are separated by home and away games for more accurate predictions.

​
Real-Time Odds Monitoring

Odds are automatically refreshed every 5 minutes via Vercel cron jobs, ensuring you always have the latest lines.
We track odds from all major sportsbooks:
  • DraftKings
  • FanDuel
  • BetMGM
  • Caesars
  • PointsBet
  • BetRivers
  • And more…
Monitor how odds change over time to identify sharp money and market sentiment.
