OptionContractSizeOverride

V8 Message Definiton

The deliverable of ONE option series where it differs from its root/expiry. Euronext adjusts a chain for a corporate action by re-sizing individual series in place (e.g. FRO on Oslo: 102 shares per contract beside 100-share series under the same root), where Eurex mints a new root (CFRv1). The root and expiry rungs cannot describe a chain whose series deliver different amounts, so the answer for such a series lives here, at the option rung. PRECEDENCE RUNS OPTION OVER EXPIRY OVER ROOT: when this row is loaded with underliersPerCn > 0, Option.UnderliersPerCn answers from it; otherwise the option falls back to OptionExpiry.UnderliersPerCn (which itself falls back to the root). A zero here is NOT POPULATED, never an override to zero. No row means the series delivers what its root says. OPTION RUNG - NO SPINE ROW. pkey is okey:OptionKey, one rung below OptExpiryDefinitionV3 (ekey) and RootDefinitionV3 (root).
