A LONG-SHORT, MULTI-INSTRUMENT, NET-DIRECTIONAL trend basket across ~10 confirmed-full-history Binance USD-M majors (BTC, ETH, SOL, BNB, XRP, ADA, DOGE, AVAX, LINK, LTC) whose signal is the classic DONCHIAN / TURTLE CHANNEL BREAKOUT -- a PARALLEL classical trend system to the promoted equal-weight Absolute-Momentum basket (holdout Sharpe 2.17), NOT a refinement of it. KEY DISTINCTION: the promoted basket trades trend STATE (price vs SMA -- profitable in trend MIDDLES); this trades trend INITIATION (breaking an N-day price range -- profitable at trend STARTS). This is the single most important diversification axis in managed futures: real CTA funds run BOTH moving-average and breakout systems precisely because their entry timing DECORRELATES, so this is portfolio-ADDITIVE rather than a weighting/signal tweak of the same SMA signal. It avoids every closed/prohibited path: NOT single-asset (alt-TSM and BTC-trend are dead -- single legs, including the single-asset ETH Donchian that collapsed, do not generalize; the DIVERSIFIED basket is the validated structure); NOT a WEIGHTING refinement (inverse-vol falsified -- this stays EQUAL-WEIGHT, the promoted weighting); NOT reversion/microstructure/options/funding/seasonality (all dead/walled). MECHANISM (per leg, classic dual-channel Turtle state): a leg is LONG when its most-recent entry_channel-day HIGH breakout is more recent than its most-recent exit_channel-day LOW breakout, and SHORT in the mirror case -- i.e. each leg holds the direction of the last range breakout until the opposite (shorter) channel breaks. This is dense (every leg is always positioned), net-directional (signed sum of legs), and the canonical breakout trend-follower. EVERY design choice respects the hard engine walls: (1) FULL-FLATTEN-AND-REOPEN sizing every weekly rebalance (close ALL legs, recompute states, reopen equal-weight summing to <=100% gross) -- the PROVEN pattern that bounded the promoted basket at ~24%, NOT the long-only held-winners pattern that proved uncappable. (2) EQUAL-WEIGHT (the validated, promoted weighting), NOT inverse-vol (falsified). (3) NET-DIRECTIONAL. (4) PURE OHLCV (no ticks/2-day-wall, options/unwired, funding/data-ends-2024). (5) WEEKLY rebalance -> trade count and fee drag near the promoted basket's, not the inverse-vol basket's 2860-trade bleed. Per the 'favor simpler' guidance, 3 tunables (entry_channel, exit_channel, rebalance_period).
