What changed?

Recorded moneyline prices

Prices move at a fixed selection; a change in a totals line is a different contract. Collection runs independently of opening this notebook.

Latest available books and main / alternate totals

Current board coverage may no longer include completed games. An empty board is not proof that no historical quotes were collected.
