Estratégia de Emulação Renko sem Repintura

Emula tijolos Renko usando preços de fechamento e opera em transições de padrão sem repintura.

Detalhes

  • Critérios de entrada:
    • Após a formação de um novo tijolo, comprar quando a direção do tijolo anterior e a sequência de preços mostram continuação de alta.
    • Vender na sequência inversa.
  • Comprado/Vendido: Ambos.
  • Critérios de saída: Fechar posições quando a direção do tijolo se inverte.
  • Stops: Não.
  • Valores padrão:
    • BrickSize = 3
    • CandleType = TimeSpan.FromMinutes(1)
  • Filtros:
    • Categoria: Padrão
    • Direção: Ambos
    • Indicadores: Nenhum
    • Stops: Não
    • Complexidade: Intermediário
    • Período: Qualquer
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
