A LONG-SHORT, single-instrument, pure-OHLCV momentum-confluence trend follower on LTCUSDT.BINANCE (USD-M perpetual), 4H primary bar + 1D trend confirm. This is a DELIBERATE stay-inside-the-survivor-class move: the ONLY mechanism that has ever reached paper in this factory is exactly this recipe on a DEEP major (BTC Sharpe 1.99, ETH 1.05, ADA 1.60 all promoted). The graveyard shows the recipe dies overfit when ported to NOISY alts (XRP, LINK, SOL, BCH, ATOM, DOT all overfit/fee_edge) and dies fee_edge when sped up (ETH-1H). The real discriminator between survivors and failures is INSTRUMENT NOISE, not the mechanism. LTCUSDT is the obvious un-mined candidate that shares the survivors' character: 2020-listed on Binance USD-M with multi-year 4H/1D history, top-15 perpetual liquidity, and distinct multi-week halving-cycle trend regimes — a low-noise, mean-persistent price series far closer to BTC/ETH than to the SOL/LINK failures. LTC is completely absent from the failure list and the corpus (which is 62% BTC recently), so this simultaneously exploits the survivor family AND diversifies away from BTC concentration. Kept to 3 parameters (fast_ema, ema_ratio, atr_mult) to match the survivors' complexity — NO regime/efficiency/volume gate is added, per L92 which shows gates reduce trade count without adding edge.
