Disclosed rule, native span, and publication lag
Documented structure covers three DEM++ stop horizons (short/medium/long) with close-based bullish/bearish flips on prior support/resistance, next-session guidance, diffusion 0–3 aboveness staging, and per-stop 20-year duration-exceedance top/trough probabilities with 85%+ conviction gated on stop crosses. Native observation span and publication lag are unavailable on-row; causal default is lag>=1. Evergreen PRO page (no article date); daily 08:00 GMT / weekly Sat–Sun refresh windows.
Approach and variants
Nine candidate families with public proxies (^GSPC, SPY, QQQ, IWM, EFA, GLD, IEF, BIL) plus lagged weekly TRENDEX TDIFF overlays. Twenty-nine labeled variants executed; see research/findings/1598.md and research/findings/campaigns/1598_trial_ledger.json.
Disposition
exploratory_tested_proxy — Other/Research publication only; NO-GO for native Trendex DEM++/diffusion/probability parity; not promoted to playable Indicators.
