Esta estratégia gera sinais de negociação através do cálculo de linhas médias móveis rápidas e lentas e combinando o indicador Parabolic SAR. Ela pertence à estratégia de tendência seguinte. Quando o MA rápido cruza o MA lento, a posição longa será aberta. Quando o MA rápido cruza abaixo do MA lento, a posição curta será aberta.
A estratégia pode ser otimizada nos seguintes aspectos:
Esta é uma típica combinação de média móvel dupla cruzada e indicadores de tendência após a estratégia. Comparando direções de MA rápidas e lentas, a tendência do mercado é determinada. Vários indicadores de filtro são usados para evitar falsos sinais. Ao mesmo tempo, a função stop loss é implementada para controlar a perda por negócio. A vantagem é que a lógica da estratégia é simples e fácil de entender e otimizar. A desvantagem é que, como uma ferramenta de tendência grosseira, ainda há espaço para melhorar a precisão do sinal, introduzindo modelos de aprendizado de máquina, por exemplo.
