Estratégia de Rompimento do Range de Abertura NY - Stop por MA

Opera Rompimentos do range de abertura de Nova York 9:30-9:45 com saídas opcionais baseadas em média móvel. As entradas ocorrem na vela seguinte ao rompimento se estiver dentro do tempo limite e o preço se alinhar com o filtro de média móvel.

Detalhes

  • Critérios de entrada:
    • A vela anterior fecha além da máxima do range de abertura (comprado) ou da mínima (vendido) antes do horário de corte.
    • A vela atual é a primeira após o rompimento e satisfaz o filtro de MA quando habilitado.
  • Comprado/Vendido: Configurável via TradeDirection.
  • Critérios de saída:
    • Stop no lado oposto do range de abertura.
    • Take profit conforme TakeProfitType: risco-retorno fixo, cruzamento de média móvel ou ambos.
  • Stops: Sim, nos limites do range.
  • Valores padrão:
    • CutoffHour = 12
    • CutoffMinute = 0
    • TradeDirection = LongOnly
    • TakeProfitType = FixedRiskReward
    • TpRatio = 2.5
    • MaType = SMA
    • MaLength = 100
    • CandleType = TimeSpan.FromMinutes(1)
  • Filtros:
    • Categoria: Rompimento
    • Direção: Configurável
    • Indicadores: Moving Average
    • Stops: Sim
    • Complexidade: Intermediário
    • Período: Intradiário
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
