A LONG-SHORT, single-instrument, pure-OHLCV momentum-confluence strategy on LINKUSDT.BINANCE USD-M perpetual. It replicates the ONE mechanism family with demonstrated positive, robust, fee-clearing edge in this factory — the selective dual-timeframe momentum confluence (paper-stage BTC survivor, Sharpe ~1.99) — while deliberately avoiding the failure modes the session has proven fatal. It does NOT use a generic single signal (breakout / range-MR / channel are now CONFIRMED to have negative per-trade expectancy on measurable samples), it is NOT a majors cross-sectional rotation (banned by L32), and it is NOT a low-frequency or options/supplementary idea (which die unmeasurable or in the developer stage). Instead it is breadth-diversification of the proven edge onto an UNCORRELATED major (LINK — oracle/tech-narrative driven, distinct from the BTC/ETH beta cluster and from the explosive-alt XRP instance), which is exactly how a real book compounds a working signal across instruments. Two guards against the overfit that killed the prior confluence ports: (1) a DISTINCT, structurally-robust confluence construction — a 4H EMA-cross for primary momentum AND a 1D swing-structure (higher-highs/higher-lows vs lower-lows) for the slow confirm — rather than a param-heavy momentum-sign fit; (2) a small 3-parameter surface. It sits in the proven fee-viable / measurable zone: 4H swings holding 1-4 days capture 3-8%+ LINK legs (far above the ~0.10% fee), and ~120-200 signals over multi-year Binance history give a robust, measurable sample. It fills the under-target LONG-SHORT bucket (13.4% vs an 86%-long-only book) and adds genuine symbol diversity. Simple pure-OHLCV single-instrument standard indicators → survives the developer without swaps/timeouts.
