Estratégia Autostop

Estratégia utilitária que define automaticamente take profit e stop loss para posições abertas. Não gera sinais de negociação. Quaisquer posições abertas externamente são protegidas usando distâncias fixas.

Detalhes

  • Critérios de entrada: Nenhum, as ordens são gerenciadas fora da estratégia.
  • Comprado/Vendido: Ambos.
  • Critérios de saída: Apenas ordens de proteção.
  • Stops: Usa StartProtection para colocar take profit e stop loss fixos.
  • Valores padrão:
    • MonitorTakeProfit = true
    • MonitorStopLoss = true
    • TakeProfitTicks = 30
    • StopLossTicks = 30
  • Filtros:
    • Categoria: Gerenciamento de risco
    • Direção: Ambos
    • Indicadores: Nenhum
    • Stops: Fixo
    • Complexidade: Básico
    • Período: Qualquer
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Baixo
