Estratégia Hull Ma Stochastic

Estratégia Hull Moving Average + Stochastic Oscillator. A estratégia entra quando a direção da tendência do HMA muda com o Stochastic confirmando condições de sobrevenda/sobrecompra.

Os testes indicam um retorno anual médio de aproximadamente 94%. Funciona melhor no mercado de ações.

O Hull MA revela rapidamente a direção da tendência. O Stochastic aguarda uma queda ou rali dentro dessa tendência para acionar a operação.

Uma abordagem flexível para quem deseja sinais suaves. Stops baseados em ATR limitam a perda potencial.

Detalhes

  • Critérios de entrada:
    • Comprado: HullMA turning up && StochK < StochOversold
    • Vendido: HullMA turning down && StochK > StochOverbought
  • Comprado/Vendido: Ambos
  • Critérios de saída:
    • Mudança de direção do Hull MA
  • Stops: Baseados em ATR usando StopLossAtr
  • Valores padrão:
    • HmaPeriod = 9
    • StochPeriod = 14
    • StochK = 3
    • StochOversold = 20
    • StochOverbought = 80
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame()
    • StopLossAtr = 2
    • AtrPeriod = 14 A HMA vira para cima quando sobe depois de cair e para baixo quando cai depois de subir; uma compra é encerrada quando ela cai e uma venda quando sobe. %K é o estocástico de StochPeriod candles suavizado em StochK candles, e o %D não participa. O stop fica a StopLossAtr ATR (AtrPeriod) do fechamento de entrada e é verificado nos fechamentos dos candles. Um sinal de entrada contra uma posição aberta a inverte.
  • Filtros:
    • Categoria: Reversão à média
    • Direção: Ambos
    • Indicadores: Hull MA, Moving Average, Stochastic Oscillator
    • Stops: Sim
    • Complexidade: Intermediário
    • Período: Médio prazo
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
