US Dollar / Swiss Franc (USD/CHF) Up or Down on July 21?

Polymarket

This market will resolve to "Up" if the Pyth-published price for US Dollar / Swiss Franc (USD/CHF) at 5:00 PM ET on July 21, 2026 is higher than or equal to the Pyth-published price at 5:00 PM ET on the most recent prior trading day. Otherwise, this market will resolve to "Down". E.g., ordinarily, a market on Monday would refer to the previous Friday for its reference price, unless that Friday were a market holiday, in which case it would refer to the next most recent trading day. If no Pyth-published price is available at exactly 5:00 PM ET on a relevant day — whether due to normal feed timing, a system outage, data failure, or other technical disruption preventing verification — the most recent valid Pyth-published price prior to that day's 5:00 PM ET cutoff will be used; if no valid Pyth price exists for that day at all, the most recent prior day on which a valid Pyth price was published will be used in its place. The resolution source for this market is Pyth, specifically the US Dollar / Swiss Franc (USD/CHF) price feed page: https://pythdata.app/explore/FX.USD%2FCHF. UMA resolvers should verify against the Pyth-published prices for the relevant 5:00 PM ET timestamps.
