A LONG-SHORT, single-instrument directional strategy on BNBUSDT.BINANCE USD-M that is deliberately engineered around the ONE lever the factory's evidence shows actually beats fees: ASYMMETRIC REWARD:RISK on a fat-tailed trend leg. It is NOT the pending BTC momentum-confluence survivor (that enters on breakout STRENGTH when two timeframes agree; this enters on a PULLBACK/retracement AGAINST the short-term move but WITH the higher-timeframe trend — a different entry mechanism and a different, lower-correlation instrument). It is NOT a mean-reversion fade (L53 — those fade a stretch expecting a small revert; here the pullback is only an ENTRY TIMING device inside a confirmed trend, and the target is a large trend-continuation move, not a small revert). It is NOT a basis/carry/cross-venue idea (that family just died fee_edge again — basis capture is sub-fee), NOT a squeeze breakout (L54), NOT cross-sectional (L52), NOT options/COIN-M. BNB is chosen deliberately: it is a deep, multi-year Binance USD-M instrument whose exchange-token-driven trends are relatively CLEAN and less BTC-beta-correlated than the alts that have failed, and it has NOT been the subject of the recent trend-family failures (those were HL, ETH, SOL, AVAX). The core insight: entering on a pullback to a dynamic support lets you place a TIGHT stop just beyond the pullback extreme while targeting the full trend continuation, producing a reward:risk of ~3:1+ and an average WINNING trade of multiple percent — which is how avg_trade_return_pct clears the 0.15% futures floor with real margin, unlike breakout-chasing entries that buy far from their stop. It fills the under-represented long-short direction bucket (13.3% vs the ≥45% implied by the ≤55% long-only cap) with a simple, 3-parameter, overfitting-resistant design.
