The rules, in plain English

This market resolves to Yes if Opendoor Technologies Inc. (OPEN) closes higher than $4.00 on the final trading day of the week of September 7 (normally Friday). Otherwise it resolves to No. If the closing price equals exactly $4.00, the market resolves to No. Closing prices are taken exactly as published by Pyth, without rounding. If OPEN does not trade at all during the regular session on the final trading day of the week, the market resolves 50-50. For a standard full trading session, the closing price is the Pyth Close value of the 1-minute candle for the final minute of regular trading hours on the primary exchange. If the session is shortened (for example, due to a market holiday), the Pyth Close value of the 1-minute candle for the final minute of that shortened session is used. If there is no valid Pyth Close value for the 1-minute candle at the end of regular trading hours on the primary exchange, the market uses the last valid Pyth price during regular trading hours on the primary exchange as the effective closing price. If no valid Pyth price exists for that trading day due to a system outage, data failure, or other technical disruption, the official closing price published by the primary exchange where the security trades is used to determine the closing price for that day. If there is a stock split, reverse stock split, or similar corporate action affecting the security during the listed time frame, this market resolves based on split-adjusted prices as displayed on Pyth. The target price will be adjusted proportionally to reflect any stock splits. Resolution is based on the historical price data as shown on Pyth after any adjustments have been applied. The resolution source for this market is Pyth, specifically the Close values for the relevant 1-minute candle for Opendoor Technologies Inc. (OPEN) available at https://pythdata.app/explore/Equity.US.OPEN%2FUSD.
