Estratégia de Reversão à Média com MACD

Este método rastreia o histograma MACD em relação à sua própria média. Leituras extremas do histograma frequentemente revertem assim que o momentum diminui. Ao monitorar a diferença entre MACD e sua linha de sinal, a estratégia encontra movimentos sobreestendidos.

Os testes indicam um retorno anual médio de aproximadamente 67%. Funciona melhor no mercado de ações.

Uma posição comprada é iniciada quando o histograma MACD cai abaixo da média em DeviationMultiplier desvios padrão. Uma posição vendida é aberta quando o histograma sobe acima da média pela mesma quantidade. A operação é fechada quando o histograma volta a cruzar sua média.

Esta abordagem atende a traders confortáveis em operar contra extremos de momentum. Um stop-loss medido como percentual do preço de entrada protege contra tendências que continuam se fortalecendo.

Detalhes

  • Critérios de entrada:
    • Comprado: MACD Histogram < Avg - DeviationMultiplier * StdDev
    • Vendido: MACD Histogram > Avg + DeviationMultiplier * StdDev
  • Comprado/Vendido: Ambos os lados.
  • Critérios de saída:
    • Comprado: Sair quando Histogram > Avg
    • Vendido: Sair quando Histogram < Avg
  • Stops: Sim, stop-loss percentual.
  • Valores padrão:
    • FastMacdPeriod = 12
    • SlowMacdPeriod = 26
    • SignalPeriod = 9
    • AveragePeriod = 20
    • DeviationMultiplier = 2
    • StopLossPercent = 2
    • CandleType = TimeSpan.FromMinutes(5) Avg e StdDev são a média e o desvio padrão dos últimos AveragePeriod valores de histograma MACD, incluindo o atual. O stop é um StopLossPercent fixo do preço de entrada, vigiado também entre os candles; 0 o desativa. Um sinal de entrada contra uma posição aberta a inverte.

    • Categoria: Mean reversion
    • Direção: Ambos
    • Indicadores: MACD
    • Stops: Sim
    • Complexidade: Intermediário
    • Período: Intradiário
    • Sazonalidade: Não
