Choose your weapon. Your mission is to defeat the plurality. The option that would defeat the option that finishes with the highest percentage will resolve to Yes. All other options will resolve to No. If there is a tie when the market closes, the option that most recently held a higher percentage than the other option(s) it was tied with will be used to break the tie.

Simpler explanation:

Rock wins if Scissors finishes with the highest percentage.

Paper wins if Rock finishes with the highest percentage.

Scissors wins if Paper finishes with the highest percentage.
