The rules, in plain English
This market resolves to "Up" if Ethereum's time-weighted average price from Chainlink during the time range in the title is at or above the price at the start of that range. Otherwise it resolves to "Down". The resolution source is Chainlink's ETH/USD TWAP data stream at https://data.chain.link/streams/eth-usd-twap-60s-streams. This market uses the Chainlink TWAP data stream price, not other sources or spot markets.
