A LONG-SHORT, single-instrument, pure-OHLCV directional momentum-confluence trend follower on ETHUSD_PERP.BINANCE_CM (the CURRENT coin-margined inverse perpetual, ETH-margined). The MECHANISM is deliberately identical to the three strategies that actually reached paper_stage (BtcDualTimeframeMomentumConfluenceLS Sharpe 1.99, AdaBinanceDualTimeframeMomentumConfluenceLS 1.60, EthVolumeConfirmedMomentumLS 1.05): take a directional position ONLY when a FAST 4H momentum signal AGREES with the SLOW 1D trend, stand flat on disagreement, and trail winners with an ATR (chandelier) stop. The NOVELTY is not the signal but the VENUE and its economics. COIN-M is the most under-represented Binance venue in the corpus (2.7%, target >=5%) and, critically, it charges ~0.06% round-trip taker vs ~0.10% on USD-M — a 40% cut in the single cost line that kills 483 of our hypotheses. The proven survivor family is Binance-DEEP-LIQUIDITY-major-specific; ETH COIN-M perp is exactly that (top-liquidity Binance contract, tight book), so this is NOT the L94 anti-pattern of cloning the mechanism onto a thin Bybit/Hyperliquid venue where the swap itself is the reason it dies. This is also NOT a beta-neutral/residual/pairs reformulation (L95/L96): it keeps momentum OUTRIGHT and DIRECTIONAL, single-leg, no second fee-paying hedge. Positions are ETH-denominated (inverse contract), which gives the returns a different, portfolio-diversifying profile from the USD-M book we already hold.
