Parlays

Two modes on one route, on Hobby and above. Pass ticket to price a specific multi-leg slip; omit it to discover ranked parlays. Every leg must price on the one book you name.

Legs are independent main lines only — there is no same-game correlation modelling. Fair price and EV exclude the leg book itself (fair_excludes_leg_book), so a book is never used to grade its own number. Discover returns non-negative-EV parlays by default; an empty result with reason: no_parlays means the board loaded and nothing cleared the bar — add include=all to see negative-EV tickets too.
