Esta estrategia se basa en el método Empirical Mode Decomposition (EMD) para descomponer las series de precios y extraer características de diferentes bandas de frecuencia, combinado con la media para generar señales de negociación.
Esta estrategia utiliza el método de descomposición del modo empírico para extraer características de la serie de precios y genera señales comerciales basadas en las características extraídas, realizando una estrategia comercial estable a mediano y largo plazo. La ventaja de esta estrategia es que puede identificar eficazmente características periódicas en los precios y emitir órdenes comerciales durante grandes fluctuaciones.
