How this study works

An occurrence begins when the UTC daily reference-price return over 1 day(s) falls to or below -10%. Adjacent qualifying dates and the configured cooldown are grouped into one episode.

Forward return = ((price on T + horizon / price on T) − 1) × 100. Missing exact UTC dates are marked incomplete and excluded from aggregates. Percentiles use inclusive linear interpolation.
