La estrategia utiliza una combinación de la banda de Brin y el indicador de triple supertrend para operar. La banda de Brin se utiliza para identificar las fluctuaciones extremas de los precios, mientras que la triple supertrend proporciona una confirmación múltiple de la dirección de la tendencia a través de diferentes configuraciones de parámetros. La combinación mantiene las ventajas del seguimiento de tendencias y aumenta la fiabilidad de la operación.
La lógica central de la estrategia incluye las siguientes partes clave:
Se trata de una estrategia de seguimiento de tendencias que combina la banda de Brin y la triple supertrend para mejorar la fiabilidad de las operaciones mediante la confirmación de múltiples indicadores técnicos. La estrategia tiene una fuerte capacidad de captura de tendencias y control de riesgos, pero también se debe tener en cuenta el impacto del entorno de mercado en el rendimiento de la estrategia.
