Historical context
254 sessions- Volatility302.3%
100th percentile of the last 234 readings — unusually high. Annualised from the last twenty sessions, then ranked against the same calculation on every twenty-session window of the past year.
- Latest session+1.05%
13th percentile of the last 253 readings — low. Ranked on size and not direction, so an unusually large fall reads as unusual rather than as a low return.
- Five sessions-3.36%
37th percentile of the last 249 readings — below typical. Ranked among every five-session change of the past year, direction included.
- Twenty sessions+31.83%
92nd percentile of the last 234 readings — high. Ranked among every twenty-session change of the past year, direction included.
A percentile is the share of the past year’s readings at or below the current one. The multi-session rows keep direction, so a high rank there means a strong rise; volatility and the latest session are ranked on size alone, so a high rank means a large move either way. All of it describes how ordinary today is by this instrument’s own standards, which is a statement about the record and not about what happens next.
