Esta estratégia é um sistema de negociação quantitativo baseado no Índice de Força de Elder (EFI), combinando desvio padrão e médias móveis para geração de sinal, enquanto usa ATR para posicionamento dinâmico de stop-loss e take-profit. A estratégia calcula indicadores EFI rápidos e lentos, normaliza-os usando desvio padrão e gera sinais de negociação através de análise cruzada, criando um sistema de negociação completo.
A estratégia baseia-se em vários elementos essenciais:
A estratégia constrói um sistema de negociação completo, combinando indicadores EFI, desvio padrão e ATR. Seus pontos fortes estão na alta confiabilidade do sinal e no controle razoável do risco, embora a otimização para diferentes ambientes de mercado ainda seja necessária. A estabilidade e rentabilidade da estratégia podem ser melhoradas adicionando avaliação da condição do mercado, filtragem de volume e outros mecanismos.
