Estratégia de Reversão de Tendência Renko V2

A Estratégia de Reversão de Tendência Renko V2 opera quando a abertura Renko cruza o fechamento Renko. Utiliza blocos Renko baseados em ATR e aplica níveis de stop-loss e take-profit. As posições vendidas podem ser desativadas.

Detalhes

  • Critérios de entrada: cruzamento de abertura/fechamento Renko com janela de tempo
  • Comprado/Vendido: Ambos (vendido opcional)
  • Critérios de saída: stop loss ou take profit
  • Stops: Sim
  • Valores padrão:
    • RenkoAtrLength = 10
    • StopLossPct = 3
    • TakeProfitPct = 20
  • Filtros:
    • Categoria: Tendência
    • Direção: Ambos
    • Indicadores: ATR
    • Stops: Sim
    • Complexidade: Básico
    • Período: Renko
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
