Cold Line Builder — dial your own edge

Compose your own spread or total. Adjust the weight of injuries, weather, travel, market movement, line movement, and matchup context, and the Cold Line engine recomputes your custom number against the live market in real time. The same engine powers the board, exposed to you as dials.
