A LONG-SHORT, single-instrument directional strategy on BTCUSDT.BINANCE (USD-M perpetual) that ports the diversified conviction-composite construction to the SURVIVOR'S ACTUAL HORIZON — 4H bars gated by the daily trend — rather than the pure-daily horizon where all ~37 of this session's probes landed Sharpe ~0.47–0.64 (DSR-failing). The decisive evidence: the ONLY strategy that clears the deflated-Sharpe gate (BTC dual-TF confluence, Sharpe ~2.0) operates at 4H+1D; its edge is HORIZON-SPECIFIC and lives intraday-to-daily, while daily-bar single factors and daily composites are the weakest sampling of it. This applies the same three survival ingredients — DIVERSIFICATION (equal-weight composite of orthogonal 4H factors), SELECTIVITY (engage only when the composite AND the daily trend agree; flat otherwise), and RISK DISCIPLINE (vol-targeted size, trailing-stop winners) — but at 4H, which (a) matches where BTC's edge empirically exists and (b) gives ~6x more observations than daily, tightening the Sharpe CI toward the 0.95 DSR bar that daily probes (~0.6) provably cannot reach. It is NOT the confluence template sprayed on a ticker (L56 — the fast signal is a multi-factor composite, not a single EMA), NOT a single-signal probe (all ~0.6), NOT the two queued DAILY composites (this is 4H+1D — different horizon/sampling), NOT the regime-decayed convex family, NOT cross-sectional (L52), NOT reversion (L53), NOT microstructure/carry/basis/options (dead/infra). LOW-DOF: 4 pre-registered equal-weight 4H factors (fast momentum, close-location pressure, volume-flow, range-position — all standardized), only 3 tuned params (composite threshold, daily-trend lookback, trailing-ATR multiple). On BTC (sole recent-regime survivor). HONEST framing: this is the most-targeted remaining attempt — it tests whether the survivor's edge is STRUCTURE-general (composite at its horizon reproduces it) or CONFIG-specific (only its exact EMAs work); if the latter, it lands a near-miss, which is decisive information. Risk: ~1.5% equity/trade anchored to the trailing stop; vol-targeted size capped 20% of equity*leverage; 2x leverage cap (reads self.config.leverage).
