Calculation. Exact definition: The population standard deviation of admitted daily closing BTC/USD quotes over the trailing 1,460 days. Higher values mean the window's daily quotes were more spread out around their mean, in US dollars per bitcoin; this is dispersion of price levels, not of returns. A missing quote invalidates every window containing it, with no carry or interpolation. Day D uses the following 00:00 UTC quote; earlier quotes are retrospective closes with unknown publication time, venue and vintage, later ones keep their actual clocks, values are provisional and revisable, and the open day is a labelled partial. std(a if a > 0, otherwise undefined, 1460): the population standard deviation, dividing by N, of the latest 1,460 adjacent daily values of each UTC day's positive admitted ending-boundary BTC/USD quote.
