A LONG-SHORT, single-instrument, pure-price MOMENTUM-CONFLUENCE trend follower on SOLUSDT.BINANCE (USD-M perpetual), 4H single-bar construction. This is a targeted, evidence-driven test, not a blind re-skin. My trail draws a sharp line: the choppy laggards XRP (Sharpe 0.28), DOGE (0.45, underperforms buy-hold) and LTC (net-LOSING, -36.5%) were FAIRLY tested on 6+ years and genuinely have NO fee-clearing trend edge; but SOL's trend premise was NEVER fairly evaluated — the only SOL test (SOL-HL) was abandoned solely because Hyperliquid's ~3.4y history is too short to establish significance ('wrong venue/data'), not because the edge was absent. SOL is the strongest-trending, highest-persistence liquid alt of this cycle (huge sustained 2023-2024 up-leg, sharp down-legs) — precisely the trend character that clears fees, unlike the range-bound laggards. Routing the proven confluence mechanism (the exact recipe behind the paper-stage BTC survivor, Sharpe 1.99, and the 'optimized' ADA/BNB Binance ports) to SOL on ~5y of Binance USD-M history gives that premise a fair, significance-clearing test. SOL's higher beta also gives the widest per-trade fee margin among the plausibly-edge-bearing names. NOT a mean-reversion fade (L53), NOT a squeeze breakout (L54), NOT a channel breakout (outlier class), NOT a cross-sectional/per-name-ensemble basket (L52), NOT a market-neutral ratio (near-zero edge), NOT a NON-PRICE-feed gate (L46), NOT options/COIN-M (L50/L51). Fills the long-short gap (13.6% vs 86% long-only). To resist the #1 killer (overfit, 308x) and verification bugs: single bar type, 3 params, fixed fast-EMA length. Risk profile: ~1.5% equity risk/trade via ATR stop; vol-scaled notional = risk_budget / (atr_mult * ATR_4H) capped at 25% of equity*leverage; 2x leverage cap (reads self.config.leverage). Exactly 3 tunable parameters (slow/fast EMA ratio, daily-trend EMA length, ATR trailing multiple).
