BTC: Closing Quote Bands Daily20 - Middle

Bitcoin Closing Quote Bands Daily20 - Middle was $79,371.3 on 7 Nov 2026 (latest daily value).

The middle closing-quote band: the arithmetic mean of BTC's last 20 daily closing quotes.

Why use it. Provide the short-run average close around which the upper and lower bands are placed. How to read it. One USD/BTC line; a close above it exceeds its 20-day mean. The upper and lower bands sit two sample deviations either side and are separate lines, never summed. A missing or nonpositive quote leaves the window undefined. Points are UTC days labelled at the day start, the open day a labelled partial at its latest completed hourly quote, with no interpolation or carry; values are provisional and revisable. This is a price comparison, not a forecast.

Calculation. Arithmetic mean of 20 adjacent positive admitted daily closing quotes, requiring the full window. Historical quotes are retrospective, with unknown original publication time and venue; prospective quotes keep their actual observation and retrieval clocks. The full retained history is computed before the view is filtered.
