Volume Segmentado por Tempo Aprimorado

O Volume Segmentado por Tempo Aprimorado monitora as variações de preço ponderadas por volume. Quando o TSV está acima de sua média móvel e é positivo, a estratégia compra. Quando o TSV está abaixo da média e é negativo, vende a descoberto.

Detalhes

  • Critérios de entrada: TSV em relação à sua média móvel.
  • Comprado/Vendido: Ambas as direções.
  • Critérios de saída: Sinal oposto ou stop.
  • Stops: Sim.
  • Valores padrão:
    • TsvLength = 13
    • MaLength = 7
    • CandleType = TimeSpan.FromMinutes(5)
  • Filtros:
    • Categoria: Momentum
    • Direção: Ambos
    • Indicadores: Volume, SMA
    • Stops: Sim
    • Complexidade: Básico
    • Período: Intradiário
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
