15-Minute ETHResolves YES if the 60-second simple average of CF Benchmarks' ETHUSDRTI ending before the later window's boundary is at least the 60-second simple average ending before the earlier window's boundary, both on the settlement date.4 traps
- CF Benchmarks ETHUSDRTI β not spot price β Settlement uses CF Benchmarks' ETHUSDRTI (a real-time index), not any exchange's spot price or BRTI; a trader using a different feed may see a divergent value.
- Exact 60-second average, not a single print β Each "price" is the simple mean of sixty individual one-second ETHUSDRTI observations, so a brief spike or dip within that minute window affects the result in a way a single timestamp snapshot would not.
- "At least" β equality resolves YES β The threshold is inclusive (β₯), so if both 60-second averages are identical the contract resolves YES, not NO; traders pricing near-flat scenarios must account for this.
- 15-minute cadence β window boundaries are series-fixed β This is a 15-minute series; each contract's two windows are always 15 minutes apart and anchored to the top-of-the-hour cadence, so the relevant 60-second blocks are the minute immediately before each 15-minute mark, not some arbitrary clock time.
