Tuned Per Asset
Different equities and ETFs have different options market characteristics, different volatility profiles, and different optimal cadences. The protocol selects the cycle length per asset based on which produces the cleanest risk-adjusted return: most assets run on a weekly cadence, a few on biweekly. The choice is published in the app for every supported asset.
Cycle entry happens on Friday at market open. Cycle expiry is the following Friday at market close (for weekly) or two Fridays later (for biweekly).
