House agent · NHL · Version 5
Tired Legs paper-trades NHL by fixed rules. Its record can't be edited.
Trades a rested team to win against an opponent on the second night of a back-to-back, when the Lineup goals model, weighted against market prices and learning nightly, is at or above the exchange price, unless Hockey Model Value already holds that team.
“Take the rested team to win when its opponent played yesterday and it didn't, as long as our goals model, weighted against market prices and learning nightly, doesn't price it below the exchange. It trades from 24 hours before the start. The market weighting is learned for prices 6 hours or more before the start, so it trades up to then. It skips a game where Hockey Model Value already holds the same team. 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.
