This market resolves to "Up" if BNB's time-weighted average price (TWAP) from Chainlink during September 11, 11:10AM-11:15AM ET is greater than or equal to the price at the start of that time range. Otherwise it resolves to "Down". The resolution source is Chainlink's BNB/USD TWAP data stream at https://data.chain.link/streams/bnb-usd-twap-60s-streams. This market is about the Chainlink TWAP price, not spot prices from other sources or markets.
