Estratégia Volume Weighted Price Breakout

Esta estratégia combina uma média móvel com uma média móvel ponderada por volume (VWMA). Quando o preço opera acima da VWMA, sugere que os compradores são dominantes. Um rompimento ocorre quando o preço cruza a VWMA pelo lado oposto.

Os testes indicam um retorno anual médio de aproximadamente 40%. Funciona melhor no mercado de criptomoedas.

As operações se alinham com a direção da VWMA e usam a média móvel simples como filtro de tendência de nível superior. As saídas ocorrem quando o preço reverte em relação à média móvel.

O objetivo é capturar rompimentos apoiados por volume.

Detalhes

  • Critérios de entrada: Preço acima ou abaixo da VWMA com confirmação da MA.
  • Comprado/Vendido: Ambas as direções.
  • Critérios de saída: O preço cruza a MA na direção oposta ou stop.
  • Stops: Sim.
  • Valores padrão:
    • MAPeriod = 20
    • VWAPPeriod = 20
    • CandleType = TimeSpan.FromMinutes(5)
  • Filtros:
    • Categoria: Rompimento
    • Direção: Ambos
    • Indicadores: VWMA, MA
    • Stops: Sim
    • Complexidade: Intermediário
    • Período: Intradiário
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
