A LONG-SHORT, SINGLE-INSTRUMENT, single-venue strategy on DOGEUSDT.BINANCE USD-M perpetual whose edge is STRUCTURAL, not directional price-prediction. The perpetual mark price is anchored to the underlying index by the funding mechanism; when aggressive one-sided retail leverage pushes the perp mark to an EXTREME premium (or discount) versus the spot index, that dislocation is mechanically forced back toward fair value by (a) the impending funding payment penalizing the crowded side and (b) basis arbitrageurs. The strategy measures the mark-index premium (in bps of index), z-scores it over a rolling window, and FADES extremes: when premium is extremely POSITIVE (perp rich, longs crowded, about to pay funding) it goes SHORT the perp; when premium is extremely NEGATIVE (perp cheap, shorts crowded) it goes LONG. Position is held for 1-2 funding intervals (8-24h) to capture BOTH the premium convergence AND the funding cash flow, which flows to the side the strategy holds (short collects when funding positive, long collects when funding negative). DOGE is chosen deliberately because its retail-heavy, high-leverage participant base produces frequent, large premium dislocations — far larger than BTC/ETH — which is exactly what makes the per-trade capture clear the fee floor. This is NOT the previously-failed unhedged funding-contrarian swing (which faded price momentum and lost to trend) nor a cross-venue delta-neutral carry (which dies at sandbox two-leg injection, L69): it is a single-leg, single-venue fade of a MICROSTRUCTURE dislocation with the funding tailwind, using only data feeds confirmed injectable in the Layer-3 sandbox (the XRP perp-basis strategy just cleared QA using this exact mark/index premium feed). All per-bar computation is O(1) via incremental rolling mean/std (no full-series rescans) to avoid the smoke-test timeout that killed prior premium/vol strategies. Only 2 free parameters (entry z-threshold, convergence-exit z-level) plus a hard time stop, to stay well clear of the overfit graveyard.
