A LONG-SHORT, single-instrument DIRECTIONAL momentum-ignition strategy on the XRP USD-M perpetual that uses the PERP-vs-INDEX BASIS VELOCITY as the fuel gauge, not the price. When the perpetual's premium over its index (the mark-minus-index / premium-index feed) is EXPANDING rapidly — accelerating leveraged demand piling in on one side — price tends to CONTINUE in that direction for a short burst before the leverage exhausts. The strategy goes LONG when the basis is rapidly widening positive AND price confirms an up-break, SHORT when the basis is rapidly widening negative AND price confirms a down-break, then EXITS FAST when the basis-velocity stalls (the ignition is spent) to sidestep the reversion that follows. This is deliberately NOT my two pending Hyperliquid proposals (OI-confirmed breakout, funding-contrarian reversion): different venue (Binance), different asset (XRP), different feed (premium-index velocity), and OPPOSITE sign to the funding-reversion idea (this RIDES the crowd's ignition burst rather than fading crowded extremes). It is NOT a pure-OHLCV trend clone (the entry is gated by a supplementary microstructure signal with real predictive content), NOT a fade, NOT a market-neutral pair/basket (L45), NOT options/CM. XRP is a high-retail-leverage name whose basis routinely blows out on positioning surges, giving a strong, frequent ignition signal. Fills the under-represented long_short bucket (14.2% vs ~45% target).
