MODEL ADOPTION #988: REJECT — LEDGER BENCH: Apply filter: Quarterly phase = ACCUMULATION — improves win rate from 31.6% — E8 Intelligence Research

Abstract

DECISION: REJECT ELEMENT: The "Quarterly phase = ACCUMULATION" filter is not a concrete, testable edge compatible with E8 geometry timing. It is a macro‑regime label derived from price‑action heuristics, not from the E8‑node/Gods‑Clock rhythm logic. The backtest (n=120) is too small to validate a regime‑dependent filter, and the live projection (n=5) is statistically meaningless. The filter would reject trades during distribution/markdown phases where E8's FADE polarity edge is designed to exploit mean‑reversion and exhaustion. This introduces a regime‑timing dependency that conflicts with the model's core rhythm logic. EXPECTED IMPACT: Win‑rate improvement from 31.6% to 44.2% is likely an artifact of overfitting to a specific 120‑trade window. In live trading, the filter would reduce trade frequency by ~25%, and the missed trades during non‑accumulation phases would likely have higher average PnL (since E8's FADE edge thrives in volatile, trending phases).
