A LONG-SHORT, single-instrument, pure-OHLCV directional strategy on XRPUSDT.BINANCE (USD-M perpetual, 4H primary + 1D trend confirm). It belongs to the ONE mechanism family that has ever survived in this factory — slow directional momentum on a liquid major, long-short — but it changes the ENTRY PRIMITIVE, which is the actual lever on fee-survival. The three deployed winners (BTC/ADA/ETH dual-TF confluence) and every dead sibling (BNB/DOT/LTC/LINK) all enter on STRENGTH: they buy when the 4H signal breaks out in the trend direction. Chasing breakouts pays the worst fill of the swing, so per-trade capture is small and repeatedly dies in the fee band (see LTC -0.237%/trade, SOL 1.022 PF). This strategy instead enters on WEAKNESS INSIDE STRENGTH: within a 1D-confirmed uptrend it waits for a 4H pullback to a fast EMA and buys only when the next 4H bar RE-accelerates in the trend direction (close back above the EMA with a higher high). The better entry price mechanically raises average per-trade capture above the ~0.10% round-trip cost. This is NOT a regime/efficiency/volatility GATE bolted onto a breakout (the dead L92 class) — the trend filter and the entry trigger are the same two objects the winners already use; only the trigger geometry (pullback-and-resume vs breakout) is different. Instrument choice is deliberate diversification: XRP is a top-liquidity major (tight spreads, 6+ years of USD-M history) yet lightly used in the factory relative to the BTC-saturated corpus, and its prior deaths were a different mechanism entirely (volume-climax VWAP reversion, L89), so this is a fresh instrument-x-mechanism cell, not a symbol-swap of an existing winner.
