Estratégia de Rompimento do Candle das 2:45 AM

Esta estratégia intradiária monitora o candle das 2:45 AM e opera rompimentos de sua máxima ou mínima dentro das próximas barras. Quando o preço supera a máxima do candle, entra em uma posição comprada; quando o preço cai abaixo da mínima do candle, abre uma posição vendida. As posições são fechadas no final da janela de observação se nenhum rompimento oposto ocorrer.

Detalhes

  • Critérios de entrada:
    • Comprado: O preço rompe acima da máxima do candle das 2:45 AM dentro dos próximos LookForwardBars candles.
    • Vendido: O preço rompe abaixo da mínima do candle das 2:45 AM dentro dos próximos LookForwardBars candles.
  • Comprado/Vendido: Ambos.
  • Critérios de saída:
    • Fim da janela de observação ou rompimento oposto.
  • Stops: Nenhum.
  • Valores padrão:
    • TargetHour = 2
    • TargetMinute = 45
    • LookForwardBars = 2
    • CandleType = candles de 45 minutos
  • Filtros:
    • Categoria: Rompimento baseado em tempo
    • Direção: Ambos
    • Indicadores: Nenhum
    • Stops: Não
    • Complexidade: Baixo
    • Período: Intradiário
    • Sazonalidade: Sim
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
