Current definition val-v1. Charts stamped with it were computed by src/metrics/valuation.py, and every value plotted for a past date could have been computed on that date.
Two kinds of thing live here, and the difference matters more than the code.
Folklore multiples — the Golden Ratio Multiplier and the two-year multiplier — are a moving average times a constant somebody picked because it fitted the chart. There is no mechanism. They are included because they are widely watched and a library that omits them is answering a question nobody asked, and every one of them ships with its own empirical expanding percentile beside the constant, so a reader can see whether the folklore level and this asset's actual record agree. Often they do not.
The asymmetric fan is the honest counterpart: expanding quantiles of the log regression residual, so the band above the fit and the band below are allowed to be different widths. Crypto's residual distribution is not symmetric and a ±k-sigma band asserts that it is.
Everything is expanding. A multiple's percentile in 2015 is computed from 2015's record and no later day, exactly as risk.py does it.
Newest first. Each entry says what changed and whether values that had already been published moved with it, followed by the sentence from the module that decided the verdict.
golden ratio multiplier, two-year multiplier, expanding multiple percentiles, asymmetric quantile fan.
The first version of this metric. There is no earlier definition to restate.
44 charts name this metric in their readout line. 33 name it first, so a count taken from the leading stamp alone reports 33 rather than 44. A chart built on several definitions carries all of them, and being second in that list is not the same as being unused.
