XRP Perp 4H Funding-Extreme Momentum Continuation (Single-Instrument USD-M, Long-Short, Validated-Template Decorrelated Breadth)

A long-SHORT, SINGLE-INSTRUMENT, single-venue MOMENTUM-CONTINUATION strategy on XRPUSDT.BINANCE USD-M perpetual futures using 4-HOUR bars, replicating the ONE mechanism validated this session — funding-extreme momentum FOLLOW (SOL fade→follow flip validated at PF 1.30) — on a third, deliberately DECORRELATED asset to build a robust multi-asset book of the proven edge. Funding is a SIGNAL only (never credited as a cash flow; P&L is fully price-based and creditable). Thesis: extreme funding marks strong, persistent leveraged-positioning demand that CONTINUES in price (the session proved fading it loses across SOL/ETH, while FOLLOWING it validated). XRP is chosen specifically because its funding extremes are driven by idiosyncratic catalysts (payments/regulatory narrative, SEC-case milestones, ODL adoption cycles) that fire at DIFFERENT times than the SOL (L1) and DOGE (meme) members of the pending validated-template book — so the resulting strategy's returns decorrelate from them, which is the point of breadth-building a proven signal rather than stacking correlated copies. This is explicitly DISTINCT from the FAILED 'XRP funding-crowding-veto breakout' (where funding was an inert VETO on a price Donchian breakout that overfit): here funding-extreme is the PRIMARY momentum trigger — the construction that validated on SOL, not the construction that failed. It stays on the only confirmed-testable substrate (OHLCV + funding, both dense across full history) on the clean single-instrument USD-M MARGIN path, avoiding every structural blocker: NOT supplementary-data-gated (OI/liquidations/options-IV are recent-only, untestable), NOT BINANCE_SPOT/CASH (metric/fill bug), NOT COIN-M (not backtestable), NOT cross-venue/Hyperliquid (basis artifact), NOT a multi-instrument pair (extra-leg feed bug), NOT funding-carry (no uncreditable cash flow), NOT a breakout (overfits), NOT a funding-veto overlay (proven inert), NOT a slow regime signal (untestable trade count). 4H cadence on XRP's frequent funding extremes guarantees enough trades to populate walk-forward and holdout. Kept to ~4 parameters to match the validated low-overfit template.
