Split a fixed stake so both YES legs pay the same if either bucket hits. Prices can be 14, 14¢, or 0.14.
Spend on each bucket is proportional to its YES price, so the cash-out is identical whichever of those two wins. This is not a lock on the whole market: if any other bucket wins, both legs expire at $0. Formula: spend = stake × price / (pA + pB). Payout = stake / (pA + pB).
