Esta estratégia utiliza o indicador ADX para determinar a tendência do mercado, combina-se com o indicador DMI para determinar a direção, utiliza a inclinação do ADX para medir a força da tendência, define o nível chave do ADX para filtrar mercados não em tendência e usa uma média móvel para filtrar os sinais comerciais.
Esta estratégia utiliza plenamente a força do ADX na determinação da tendência e do momento, combinada com o DMI para análise de direção, formando um sistema completo de tendência. O filtro MA reduz efetivamente o ruído.
