A DELTA-NEUTRAL, CROSS-VENUE cash-and-carry strategy that holds a REAL spot long on BINANCE_SPOT and an equal-notional SHORT on the HYPERLIQUID BTC perpetual to harvest Hyperliquid's funding premium. This deliberately differs from the factory's existing Binance-internal spot-perp carry (IntraBinanceSolSpotPerpFundingCarryDeltaNeutral1H) and the perp-perp funding-spread rotations: the short leg lives on HYPERLIQUID, NOT on the BINANCE USD-M perp that the abandon-cluster confirmed is over-exposure-corrupted. Both chosen venues size correctly (BINANCE_SPOT is a CASH account; HL sizing is clean at ~64-90% avg_position_pct per prior runs), so this construction is immune to the USD-M position_size->order-qty defect that ruined the directional perp runs. HL funding accrues HOURLY (vs Binance's 8h), and crypto perps structurally trade at a premium (longs pay shorts) in neutral-to-bull regimes, so a perp short collects funding. The strategy only deploys when funding is ELEVATED enough that accrued carry over the expected hold beats the ~0.29% round-trip fee, keeping it firmly fee-positive. Few parameters (funding entry threshold, funding exit floor, basis stop, per-leg notional) keep overfitting risk low, addressing the recurring overfit failures. The 1H funding-check cadence accumulates many more trades than a daily-cadence HL strategy, sidestepping the HL data-sparsity wall that abandoned the daily Donchian/funding-reversion runs.
