How this works

1. Live scores

We poll ESPN every 5 seconds for real-time game state: score, time, period.

2. ML model

Our model (trained on 60K+ games) predicts the fair win probability from game state + Elo ratings.

3. Compare

When fair probability exceeds the market ask by 8c+, that's a tradeable edge.
