Calculation. m3 / m2^1.5 of the last 365 daily returns, with m2 and m3 their population central moments. From CryptoKeyhole's own US dollar price chart of PROM, closed periods only. Returns are 24-hour returns r = close / close 24 hours earlier - 1; daily values use the closes of UTC days, hourly values recompute the same statistic at every hour from the closes 24, 48 ... hours before it, so a day's last hour gives its daily value wherever the hourly closes are complete. A window of N days needs N + 1 closes exactly a day apart: a missing close leaves every window that needs it empty, nothing is filled in. The open UTC day shows a labelled partial at the latest completed hour. History starts once the price chart has the window's closes; it is a description of the past, not a forecast.
