cycle-v3 · Complete runs, each counted once, on daily closes. The distribution is close to what independent coin flips would produce, which is the useful finding: a six-day losing streak feels like information and the record says it is roughly what chance delivers. Runs longer than 12 are omitted from the bars and are rare enough to count individually.

Every value plotted for a past date could have been computed on that date. Normalised series expand their window rather than scaling against the full history, so nothing here is drawn using information that did not exist yet — which is also why the early years of a normalised series are dropped rather than shown against a range of one.
