A LONG-SHORT, SINGLE-INSTRUMENT, DAILY time-series momentum strategy on DOTUSDT.BINANCE (USD-M perpetual) that extends the factory's ONE empirically-validated, promoted edge — daily trend-following on majors — to a deep-history L1 major the long-short trend book does not yet cover and that adds a decorrelated return stream (DOT's Polkadot/parachain ecosystem drivers differ from the BTC/ETH/SOL/BNB/LINK/AVAX sleeves). It deliberately uses the SAME proven construction as the promoted BTC/ETH/SOL TS-momentum siblings (price-vs-moving-average trend sign) rather than a novel signal, because the repeated lesson of this session is that ONLY the validated daily-trend family survives — every orthogonal variant has either lacked edge (intraday VWAP/taker fades wiped out, multi-day reversal negative) or hit an engine wall (multi-instrument aggregation, options settlement, HL short-history overfit). This is therefore a deliberately conservative, high-survival-probability extension, engineered around every confirmed landmine: SINGLE-INSTRUMENT / SINGLE-VENUE / SINGLE-ACCOUNT (no multi-instrument equity/return aggregation artifact); PURE OHLCV (no funding / OI / liquidations supplementary-data dependency, avoiding the OI cache-gap and funding-accrual issues seen elsewhere); DEEP MULTI-YEAR Binance history (walk-forward + holdout span multiple real regimes, unlike the HL 155-day data wall); DAILY bars (the validated cadence — NOT the intraday-bar breakout/fade variants that are chop-dominated and negative on majors). It is built to PASS where LTC trend FAILED: LTC failed because it is a range-bound laggard that chopped a naked trend-cross (16.8% win rate). DOT, by contrast, has exhibited SUSTAINED DIRECTIONAL REGIMES on BOTH sides (the 2021 parachain-narrative advance and the multi-year 2022-2024 decline) — sustained trends, not chop — which a LONG-SHORT trend book monetizes in both directions, and a LONG-TERM REGIME FILTER keeps it flat during directionless transitions. Low parameter count (~3-4 knobs) to resist overfitting.
