Reglas preregistradas: velas cerradas 1h UTC, SMA20/50 con rolling de pandas, ventana válida de 51 velas consecutivas finitas con volumen positivo para entradas, cruce alcista entra, cruce bajista sale, stop -2%, ROI desactivado, una posición long, sin DCA/trailing. Órdenes market simuladas. Riesgo: cap = min(1000, 10% capital, 0.25% capital / 0.026, max motor). `custom_stake_amount` devuelve 0.0 ante cualquier error/dato inválido sin lanzar (evita fallback del motor a proposed_stake). `confirm_trade_entry` revalida notional <= cap y solo long, False ante cualquier duda.
