BTC: Bull Window 2010-2011 - Drawdown

How far BTC's daily closing quote sits below the highest close reached so far in the fixed window 2010-07-17 to 2011-06-08, in percent.

Why use it. Measure pullbacks from the running high inside this selected bull window. How to read it. 0% means the close is at the window's highest close to date; -50% means half of that high. The high is this window's running closing maximum, not a lifetime high or an intraday high. A missing start-date quote leaves the whole curve on hold, and any interior gap makes later values unknown. This is a retrospective selected window, not a predictive cycle classifier. Points are closed UTC days labelled at the day start; values are provisional and revisable.

Calculation. Drawdown = 100 × (close / running maximum close - 1), where the running maximum covers positive admitted daily closing quotes from 2010-07-17 to the displayed day, within the window ending 2011-06-08. Historical quotes are retrospective, with unknown original publication time and venue. No open-day partial, interpolation or carry is used.
