The moving-average vocabulary — kernel K2 of the corpus assessment
(docs/notes/financial-indicators-assessment-2026-07.md §4).
~25 studies in the corpus expose a "MA Type" input, and every one of them
means the same menu. Naming that menu once, in one place, is what keeps
those studies thin assemblies rather than 25 private smoothers that drift
apart — a keltner with its own EMA and a disparityIndex with another is
exactly the failure mode the studies README's step 0 exists to stop.
Deliberately not in the menu (deferred, not forgotten): MAMA/FAMA
(Ehlers' Hilbert-transform adaptive MA — a different kind of animal, and
TA-Lib's own implementation is the only reference), T3 (Tillson: six
chained EMAs plus a volume-factor knob), VIDYA (CMO-adaptive, so it needs
the K6 recursion the package has not built yet) and the time-series /
linear-regression forecast MA (kernel K7, rolling regression — a
different kernel, not a smoothing rate). Each is a study-sized decision of
its own and none of the fan-out's consumers need them.
