A LONG-SHORT, SINGLE-INSTRUMENT, DAILY Donchian-channel breakout (Turtle-style) trend strategy on LINKUSDT.BINANCE (USD-M perpetual). It deliberately uses the factory's VALIDATED daily trend/breakout family — the same edge already promoted via the ADA Donchian / trend-filtered-breakout siblings and the BTC/ETH/SOL TS-momentum books — but applies it to a major the long-short trend book does NOT yet cover and that is structurally DECORRELATED from the existing trend sleeves: LINK is a DeFi/oracle-infrastructure asset whose return drivers (oracle adoption, DeFi/RWA narrative) differ from the exchange-token beta of BNB and the pure L1 beta of BTC/ETH/SOL, so it adds a diversifying trend stream rather than correlated family risk. It is engineered around every confirmed engine and edge landmine of this session: SINGLE-INSTRUMENT / SINGLE-VENUE / SINGLE-ACCOUNT, so it cannot trip the multi-instrument equity/return aggregation artifact that corrupted every pairs / rotation / fixed-weight-sleeve / cash-carry run; DAILY bars (the validated cadence — NOT the intraday-bar breakout/vol-expansion/impulse variants that are chop/whipsaw-dominated and negative on majors); no options, no funding-carry, no cross-venue. It is built to PASS where LTC trend FAILED: the LTC lesson was to screen for actual trend persistence and to not let a naked signal get chopped on a range-bound asset — LINK has historically produced sustained directional moves (2020 DeFi advance, 2021, the 2024-2025 rallies), and the design adds a 200-DAY TREND-REGIME FILTER (take longs only in a confirmed uptrend regime, shorts only in a confirmed downtrend regime) so the book stays out of the mid-channel chop that destroys breakout systems in ranges. Low parameter count (~4 knobs) to resist overfitting; thresholds set so breakouts fire an ample number of times over deep history (avoiding the no-trade Layer-3 failure).
