Exotics
User-composed combo (parlay) markets — every leg's named side must win. YES pays $1 if the whole parlay hits; a pushed or voided leg halves the payout (validator ruleset §6.6). Trade either side at the live top-of-book price below.
No combo markets.
Build one from the order form: add legs with any market's Yes/No buttons (or the terminal's Add to Combo), then Place Combo.
