Esta estratégia usa uma rede neural artificial (ANN) para prever mudanças futuras de preços e gera sinais de negociação com base nas previsões. Ela pertence à estratégia de tendência seguinte. A vantagem é que ela pode identificar tendências não lineares complexas e é adequada para negociação de médio a longo prazo.
A estratégia utiliza um modelo ANN para prever a variação percentual do próximo dia de negociação.
A camada de entrada tem apenas um nó, que é a mudança percentual do dia anterior.
A camada oculta tem 2 camadas, a primeira com 5 nós e a segunda com 33 nós.
A camada de saída tem um nó, passando por uma função de ativação linear para gerar a previsão final.
Se a previsão for maior do que o parâmetro de limiar, um sinal longo é gerado.
Esta estratégia baseada em ANN pode identificar tendências não lineares complexas e é adequada para negociação de médio a longo prazo. No entanto, a natureza da caixa preta dos modelos ANN também apresenta desafios significativos para a negociação ao vivo. Precisamos otimizar os recursos de entrada, arquitetura do modelo, ajuste de parâmetros, aprendizado de conjunto, etc., combinando com a análise técnica tradicional para um desempenho robusto no mundo real.
