A USD price level at 0.8 times the mean of BTC's last 200 daily closing quotes.
Why use it. Translate a 200-day multiple of 0.8 into a price level that can be compared directly with BTC's close. How to read it. A close below this line means the price-to-200-day-mean ratio is under 0.8. It uses the same 200-day window as that ratio and shares the USD/BTC price scale. It is a comparison level, not a guaranteed floor or forecast. Missing or nonpositive quotes leave the level unknown. Points are UTC days labelled at the day start, the open day a labelled partial, with no interpolation or carry; values are provisional and revisable.
Calculation. 0.8 × the arithmetic mean of 200 consecutive positive admitted daily closing quotes, including the displayed day. 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.
