Rompimento MACD

A estratégia de Rompimento MACD observa o MACD em busca de expansões repentinas. Quando as leituras saltam além de seu intervalo normal, o preço frequentemente inicia um novo movimento.

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

Uma posição é aberta assim que o indicador perfura uma banda derivada de dados recentes e um multiplicador de desvio. Operações compradas e vendidas são possíveis com um stop vinculado.

Este sistema se adapta a traders de momentum que buscam rompimentos precoces. As operações são fechadas quando o MACD retorna em direção à média. Os valores padrão começam com FastEmaPeriod = 12.

Detalhes

  • Critérios de entrada: O indicador supera a média pelo multiplicador de desvio.
  • Comprado/Vendido: Ambas as direções.
  • Critérios de saída: O indicador reverte à média.
  • Stops: Sim.
  • Valores padrão:
    • FastEmaPeriod = 12
    • SlowEmaPeriod = 26
    • SignalPeriod = 9
    • SmaPeriod = 20
    • DeviationMultiplier = 2
    • StopLossPercent = 2
    • CandleType = TimeSpan.FromMinutes(5) Avg e StdDev são a média e o desvio padrão dos últimos SmaPeriod valores de linha MACD, incluindo o atual. O stop é um StopLossPercent fixo do preço de entrada, vigiado também entre os candles; 0 o desativa. As bandas são a média mais e menos DeviationMultiplier desvios padrão: a linha MACD acima da banda superior abre uma compra e abaixo da inferior uma venda; uma compra fecha quando a linha MACD volta abaixo da sua média e uma venda quando volta acima. Um sinal de entrada contra uma posição aberta a inverte.
