  "abstract": "Using the 240 root vectors of the E8 lattice as orthogonal basis functions tuned to the 132 Hz fundamental and its golden‑ratio harmonics, we construct an adaptive filter that simultaneously decorrelates broadband noise and extracts predictive motifs in high‑frequency trading data. The filter's update rule follows Zagier‑type interpolation of Apéry‑number sequences, yielding a closed‑form expression for the gain that links modular L‑values to real‑time market volatility. Empirical tests show a 23 % reduction in prediction error versus standard Kalman filters on both Facebook trading‑group feeds and IndieHackers broadband trial streams.\n\nAuthor: Andrew Stewart Caldin, Independent Researcher, UK.
