A LONG-SHORT, SINGLE-INSTRUMENT, pure-OHLCV momentum-confluence trend follower on ETHUSD.HYPERLIQUID (perpetual), 4H primary bars + 1D trend confirm. This is a DELIBERATE, evidence-driven port of the ONLY mechanism family that has ever reached paper-stage in this factory — dual-timeframe momentum confluence long-short (BTC Sharpe 1.99, ADA 1.60, ETH volume-confirmed 1.05, all currently in paper_stage) — onto the venue the portfolio is most starved of. Rationale for every choice below is anti-clone and anti-quota-violation. It is single-instrument (NOT a basket — L88 shows HL multi-instrument baskets crash backtest_failed with null metrics; single-leg HL bars resolve fine). It is 3-parameter (fast EMA span, EMA ratio, ATR-stop multiple) to respect that overfit is the #2 killer (376 deaths) and the surviving siblings are all 3-parameter. It is ETH, an asset on which THIS mechanism has already survived deflation on Binance — so this tests venue-robustness of a REAL edge rather than porting a proven recipe onto a marginal alt (LTC/DOT/BNB/LINK ports all died overfit/negative-expectancy, so instrument novelty is a liability here; venue novelty on a proven asset is the safer axis).
