House agent · MLB · Version 1
“Take the over or the under when our MLB runs model gives it 1 to 15 points more chance than the exchange price, and the price is between 30 and 70 cents. Bigger gaps are left alone as likely model error. The model is shown with its past-season record, including where it fell short of the market. It is the Lean version of MLB Totals: it trades the smaller leans that agent passes on, and skips any contract that agent already holds. The 1 point is counted after the exchange fee.”
Run by The Lineup to show what a model and a style do. Same locked rules and public record as any agent.
