Estratégia Donchian Macd

Estratégia que combina o rompimento do Canal Donchian com a confirmação de tendência via MACD.

Os testes indicam um retorno anual médio de aproximadamente 148%. Funciona melhor no mercado forex.

A estratégia aguarda um rompimento de Donchian e verifica o momentum com MACD. Operações compradas ou vendidas seguem o movimento quando o MACD concorda.

Voltada para entusiastas de rompimentos que desejam confirmação. Os stops são colocados a uma porcentagem fixa do preço de entrada.

Detalhes

  • Critérios de entrada:
    • Comprado: Price breaks Donchian high && MACD > Signal
    • Vendido: Price breaks Donchian low && MACD < Signal
  • Comprado/Vendido: Ambos
  • Critérios de saída: Reversão do MACD
  • Stops: Percentual usando StopLossPercent
  • Valores padrão:
    • DonchianPeriod = 20
    • MacdFast = 12
    • MacdSlow = 26
    • MacdSignal = 9
    • StopLossPercent = 2
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() Um rompimento é um fechamento além da máxima ou mínima dos DonchianPeriod candles anteriores. A saída por reversão do MACD encerra uma compra quando o MACD cruza abaixo da linha de sinal e uma venda quando cruza acima. Um sinal de entrada contra uma posição aberta a inverte.
  • Filtros:

    • Direção: Ambos
    • Indicadores: Donchian Channel, MACD
