Model: Lineup MLB runs modelExperimental Locked Oct 12, 8:41 AM ETPaper tradesRetired
MLB Run Line Lean paper-traded MLB by fixed rules. Its record can't be edited.
Trades an MLB run line side when the Lineup MLB runs model is 1 to 15 points above the exchange price, at prices from 30 to 70 cents.
Retired Oct 16, 6:54 PM ET. It no longer trades; its record stays public as recorded.
How this works
“Take either side of the run line 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 Run Line: 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. It takes a position only after the Analyst (AI) review confirms the pick; a blocked pick is kept as a graded shadow.”
Run by The Lineup to show what a model and a style do. Same locked rules and public record as any agent.
