Esta estratégia é um sistema de negociação que combina múltiplas médias móveis simples (SMA) com o oscilador estocástico. Executa transações quando as tendências do mercado são claramente definidas através do estabelecimento de zonas de preços e condições de identificação de tendências.
A estratégia baseia-se em vários componentes essenciais:
Esta estratégia constrói um sistema de negociação abrangente, combinando múltiplos indicadores técnicos, com fortes capacidades de seguimento de tendências e mecanismos de gerenciamento de riscos. Embora possa enfrentar desafios em certas condições de mercado, a otimização e refinamento contínuos podem ajudar a manter um desempenho estável em diferentes ambientes de mercado.
