A LONG-SHORT, SINGLE-INSTRUMENT, PURE-OHLCV directional TREND-BREAKOUT strategy on ETHUSD.HYPERLIQUID using DAILY bars (full Hyperliquid history — well clear of the HL sub-hourly limit). It belongs to the ONE family the factory has actually validated out-of-sample — directional trend capture (the BTC dual-timeframe momentum survivor at Sharpe ~1.99) — but implements it through a MECHANISTICALLY DIFFERENT primitive: a Donchian channel breakout (classic Turtle), not an EMA momentum crossover. ENTRY: go LONG when the daily close makes a new N-day HIGH (breakout above the upper Donchian band); go SHORT when it makes a new N-day LOW. Between breakouts, stay FLAT. Position size = a fixed 2% equity risk divided by the ATR-based initial stop distance, capped at 25% notional. EXIT: a chandelier trailing stop — for longs, trail below the highest close since entry minus atr_mult*ATR(N); reverse for shorts — plus an opposite-side channel flip (a new N-day low while long, or N-day high while short) forces the exit/reversal. No fixed take-profit: let the directional expansion run. Only 2 tuned parameters (channel length N, atr_mult), keeping it robust against the 301-death overfit mode. This is DELIBERATELY NOT any dead family: NOT a funding/basis carry (the SOL/ETH spot-perp and cross-venue funding-differential carries all just died fee_edge/verification_loop — abandoning that family entirely), NOT COIN-M (L51), NOT options (L50), NOT a cross-sectional momentum-rank basket (L52 — this is a single instrument, no ranking), NOT an unhedged long-only structural basket (L48 — this is long-AND-short and sits flat in chop), NOT a non-price gate on a price impulse (L46 — the signal IS the price breakout, no supplementary feed), and NOT a liquidation/quarterly feed at risk of data_unavailable (L47 — ETHUSD.HYPERLIQUID daily bars have full history). It fills three under-represented buckets at once: HYPERLIQUID venue (6.1% vs 20% target), long_short direction (13.1% vs 87% long-only), and it is distinct from the SOL/HL EMA-confluence and ETH/BTC spread proposals already pending. Fee math: a genuine N-day (e.g. 20-55 day) daily breakout that trends produces multi-percent to tens-of-percent moves, an order of magnitude above the ~0.18% Hyperliquid round-trip, and trade frequency is low (a handful of breakouts per year that actually trend), so fee drag is minimal and the per-trade gross edge clears costs by a wide margin BEFORE fees are considered.
