Reference and mark

During the regular cash session the sample mark is the median of the venue book and a cash reference. Outside that session the sample switches to a damped venue index. The damping method is only partly described, so reference confidence falls. EPIC stores the venue's raw label next to the normalised field 'Mark price'.

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.
