Estratégia de Configuração de Operações do Ouro

Estratégia baseada na Média Móvel Adaptativa de Kaufman e SuperTrend. Vende quando AMA está subindo e SuperTrend muda para tendência de alta. Compra quando AMA está caindo e SuperTrend muda para tendência de baixa.

Detalhes

  • Critérios de entrada: Direção do AMA com mudança do SuperTrend.
  • Comprado/Vendido: Ambas as direções.
  • Critérios de saída: Níveis fixos de alvo e stop.
  • Stops: Sim.
  • Valores padrão:
    • AmaLength = 14
    • FastLength = 2
    • SlowLength = 30
    • AtrPeriod = 10
    • Factor = 3.0
    • TargetMultiplier = 3.0
    • RiskMultiplier = 1.0
    • CandleType = TimeSpan.FromMinutes(5)
  • Filtros:
    • Categoria: Tendência
    • Direção: Ambos
    • Indicadores: KAMA, SuperTrend
    • Stops: Sim
    • Complexidade: Médio
    • Período: Intradiário (5m)
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
