A LONG-SHORT, single-instrument mean-reversion on LINKUSDT.BINANCE (USD-M perp, 4h bars) that fades volatility overshoots back to a moving mean — deliberately at a SWING horizon (4h, ~1–2 day holds), not intraday. This directly answers the fee autopsy of every dead reversal in this factory: the taker-flow fade (avg_trade_return_pct −0.025%) and the AVAX/BNB/XRP 15m fades (18% commission) failed because their per-trade moves were <0.1%, below the ~0.10% USD-M round-trip. Here, on a high-volatility major at 4h, a genuine overshoot is 1–3% — 10–30× the round-trip — so the edge sits an order of magnitude above fees where the intraday fades could not. Mechanism: maintain an EMA mean and Keltner-style ATR bands; when the 4h close overshoots BELOW the lower band go LONG, ABOVE the upper band go SHORT, betting on reversion to the EMA. Critically it adds the discipline the dead un-gated fades lacked — a TREND GATE (only fade when a slow trend filter, e.g. the slope/position of a 200-bar EMA, is flat/ranging), so it never fights an established trend (the dominant loss source for band-fades). It extends the factory's ONE surviving non-carry mechanism (SOL intraday VWAP-reversion, paper stage) but is materially differentiated from it and from my pending MR strategies: a DIFFERENT horizon (4h swing vs 15m intraday), a DIFFERENT signal (ATR/Keltner-band overshoot vs VWAP z-score), a DIFFERENT instrument (LINK; the pending LINK cell is SPOT accumulation, opposite direction/venue), and NO session gate (unlike the pending DOGE Asian-session fade). It is NOT a basket (single-instrument, 2 fills/round-trip → sidesteps the L12 fee wall), NOT options (no trade-count wall), NOT trend (regime-distributed reversion), NOT carry (saturated), and NOT daily-low-frequency (4h fires dozens of times/year → clears the ~1-year sandbox trade-count wall that killed the 200-SMA spot strategies). 3 low parameters (EMA/band lookback, band multiple, exit) resist overfit.
