Estratégia Adx Stochastic

Estratégia que combina o ADX (Índice Direcional Médio) para a força da tendência e o Oscilador Stochastic para o timing de entrada com condições de sobrevenda/sobrecompra.

Os testes indicam um retorno anual médio de aproximadamente 172%. Funciona melhor no mercado de câmbio.

O ADX destaca a força da tendência enquanto o Stochastic identifica as correções. Sinais de compra ou venda aparecem quando o momentum vira enquanto o ADX permanece alto.

É adequado para traders que combinam seguidor de tendência com timing de oscilador. Um stop protetor percentual ajuda a controlar os drawdowns.

Detalhes

  • Critérios de entrada:
    • Comprado: ADX > AdxThreshold && StochK < StochOversold && Bullish
    • Vendido: ADX > AdxThreshold && StochK > StochOverbought && Bearish
  • Comprado/Vendido: Ambos
  • Critérios de saída:
    • Sair quando ADX < AdxThreshold
  • Stops: Baseado em percentual em StopLossPercent
  • Valores padrão:
    • AdxPeriod = 14
    • AdxThreshold = 25m
    • StochPeriod = 14
    • StochK = 3
    • StochOversold = 20m
    • StochOverbought = 80m
    • StopLossPercent = 2.0m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() Alta significa +DI acima de -DI e baixa -DI acima de +DI. StochK nas regras é o %K: o estocástico de StochPeriod candles suavizado em StochK candles; o %D não participa, por isso não tem ajuste. Uma entrada contra uma posição aberta a inverte.
  • Filtros:
    • Categoria: Reversão à média
    • Direção: Ambos
    • Indicadores: ADX, Stochastic Oscillator
    • Stops: Sim
    • Complexidade: Intermediário
    • Período: Médio prazo
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
