Estrategia ATR Reversion

ATR Reversion busca movimientos repentinos medidos en múltiplos del Average True Range (ATR). Cuando el precio supera el multiplicador de ATR, el sistema espera una reversión a la media.

Las pruebas indican un rendimiento anual promedio de aproximadamente 133%. Funciona mejor en el mercado de criptomonedas.

La estrategia abre una operación en la dirección opuesta al impulso y utiliza una media móvil para evaluar el momentum.

Las posiciones se cierran en un cruce de media móvil o cuando se alcanza el stop de volatilidad.
