A estratégia de dupla EMA é uma estratégia de tendência que identifica a direção da tendência dos preços, calculando EMAs de diferentes ciclos e usa isso para determinar entradas e saídas.
A estratégia baseia-se principalmente em dois indicadores EMA, um EMA de 9 dias de curto prazo e um EMA de 21 dias de longo prazo.
Quando a EMA curta cruza acima da EMA longa, ela é vista como preços entrando em uma tendência de alta. A estratégia irá longo para seguir a tendência ascendente. Quando a EMA curta cruza abaixo da EMA longa, ela é vista como preços entrando em uma tendência de queda. A estratégia irá curto para seguir a tendência de queda.
Os indicadores EMA podem efetivamente filtrar o ruído dos dados de preços e identificar a principal direção da tendência.
A estratégia apresenta as seguintes vantagens:
Há também alguns riscos com esta estratégia:
A estratégia pode ser otimizada nos seguintes aspectos:
Em resumo, a estratégia de dupla EMA é uma estratégia muito útil de tendência. É fácil de operar, entender e tem um excelente desempenho em mercados de forte tendência. A estratégia também tem alguns riscos que podem ser mitigados através de vários aprimoramentos para melhorar sua estabilidade.
