Reference and mark
Raw label: oracleMark. Out-of-hours method says the oracle keeps printing from venue books. Stale-input behaviour is not fully specified.
Plain English: the mark is the venue’s risk price. The reference anchor on this page is a fixed demonstration number, so basis is a layout of the formula, not a live premium to the listing exchange.
Basis methodologyReference confidence
Insufficient data. At least one required input is missing, so EPIC does not print a score.
