A LONG-SHORT, SINGLE-INSTRUMENT time-series (absolute) momentum strategy on LTCUSDT.BINANCE (USD-M perpetual, DAILY bars). This is a deliberate, conservative extension of the factory's ONE repeatedly-validated edge — time-series momentum/trend, whose SOL sibling (SolTimeSeriesMomentumLongShortSingleAsset1D) reached paper_stage (~0.69) — onto a LIQUID, DEEP-HISTORY asset the validated book does not yet cover (the existing TS-momentum-LS siblings are BTC/ETH/SOL only). After a long run of clever-but-dead ideas this session (cross-venue funding fee-dominated, COIN-M funding unbacktestable, Deribit options harness-broken, HL short-window non-generalization, microstructure verification failures), the highest-EV move is to broaden the one edge that demonstrably survives the full pipeline, on data that structurally avoids the dominant failure cause. LTC has multi-year Binance USD-M history (since 2019/2020), so walk-forward windows and the held-out recent tail each span real bull/bear/chop regimes — directly addressing the recent-regime NON-GENERALIZATION that killed the 6-month HL impulse expression. It keeps the VALIDATED trend payoff geometry (let winners run via a trend/EMA-cross exit, many small losses, fewer large winners) — NOT the inverted small-TP/large-stop mean-reversion geometry that broke the COIN-M Bollinger fade. It is pure-price (no supplementary-data coverage wall like the HL OI strategies), low-parameter (3) to resist the overfitting/sensitivity cliffs that recur, and long/short — filling the under-weight direction bucket (14.7% vs the 85.3% long-only over-weight). It is NOT any blacklisted family: not funding/carry, not options, not HL, not microstructure, not a fade.
