Triangular Moving Average (TRIMA)

What does a triangular weighting profile reveal after two correctly sized simple-average passes? Walk the evidence clock one stage at a time. This lab teaches the publication contract; it does not simulate returns, platform parity, or trade performance.

Selected expression

odd n: TRIMA_n(P) = SMA_((n+1)/2)(SMA_((n+1)/2)(P)); even n: TRIMA_n(P) = SMA_(n/2+1)(SMA_(n/2)(P))

Availability rule

An output at t may use only finite, basis-consistent observations available through t; chart alignment never moves the information clock backward.

Verified synthetic fixture

This lab is paired with datasets/implementation-fixtures.json: 96 deterministic, oldest-to-newest observations spanning oscillating, rising, and moderating regimes. It is teaching data—not market history or predictive evidence.
