Reference and mark

Sample out-of-hours mark leans on the venue's own book. The external cash reference is described as delayed when the listing market is shut. The raw venue label in this sample is markPx.

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.
