Estratégia de Trading MH Baseada em Hull Moving Average

Estratégia de rompimento baseada em Hull Moving Average.

A estratégia compara o preço de abertura com níveis dinâmicos derivados da Hull Moving Average. Entra comprado quando o preço rompe acima do nível superior e vendido quando cai abaixo do nível inferior. As posições existentes são encerradas em rompimentos opostos.

Detalhes

  • Critérios de entrada: Relação do preço com os níveis de Hull Moving Average.
  • Comprado/Vendido: Ambas as direções.
  • Critérios de saída: Rompimento oposto.
  • Stops: Nenhum.
  • Valores padrão:
    • HullPeriod = 210
    • CandleType = TimeSpan.FromMinutes(5)
  • Filtros:
    • Categoria: Tendência
    • Direção: Ambos
    • Indicadores: MA
    • Stops: Não
    • Complexidade: Básico
    • Período: Intradiário (5m)
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
