La estrategia de negociación de reversión de ruptura de volatilidad es una estrategia de negociación de reversión que rastrea los canales de precios con puntos de stop profit y stop loss móviles adaptativos.
La estrategia utiliza primero el indicador de rango verdadero promedio (ATR) de Wilder para medir la volatilidad de los precios. Luego calcula la constante de rango promedio (ARC) basada en los valores de ATR. El ARC representa la mitad del ancho del canal de precios. Luego, las bandas superior e inferior del canal se calculan como los puntos de stop profit y stop loss, también conocidos como los puntos SAR. Cuando los precios rompen por encima de la banda superior, se abre una posición corta. Cuando los precios rompen por debajo de la banda inferior, se abre una posición larga.
Específicamente, el ATR sobre las últimas N barras se calcula primero. El ATR se multiplica por un factor para obtener el ARC, que controla el ancho del canal de precios. Agregar el ARC al precio de cierre más alto sobre N barras da la banda superior del canal, o el SAR alto. Sustraer el ARC del precio de cierre más bajo da la banda inferior, o el SAR bajo. Si los precios se cierran por encima de la banda superior, se toma una posición corta. Si los precios se cierran por debajo de la banda inferior, se toma una posición larga.
Soluciones:
La estrategia de negociación de reversión de ruptura de volatilidad utiliza canales para rastrear los cambios de precios e invertir posiciones cuando la volatilidad sube. Funciona bien en mercados de rango con reversiones, generando buenos retornos si los puntos de reversión se identifican con precisión. Se debe tener cuidado de evitar que las paradas sean demasiado amplias y los parámetros sobreajustados.
