Estrategia de Rompimiento por Pendiente de MA

La estrategia de Rompimiento por Pendiente de MA observa la tasa de cambio de la MA. Una pendiente inusualmente pronunciada indica que se está formando una nueva tendencia.

Las pruebas indican un rendimiento anual promedio de aproximadamente 124%. Funciona mejor en el mercado forex.

Las entradas se producen cuando la pendiente supera su nivel típico en un múltiplo de desviación estándar, tomando operaciones en la dirección de la aceleración con un stop protector.

Atrae a operadores activos que buscan una exposición temprana a la tendencia. Las posiciones se cierran cuando la pendiente regresa hacia las lecturas normales. El valor predeterminado es MaLength = 20.
