Estratégia Elder Impulse

Estratégia baseada no Sistema de Impulso de Elder

Os testes indicam um retorno anual médio de aproximadamente 106%. Funciona melhor no mercado de ações.

Elder Impulse combina a direção da EMA com a cor do histograma do MACD. Barras verdes acima da EMA impulsionam posições compradas, barras vermelhas abaixo impulsionam vendidas, e barras neutras sinalizam saídas.

Ao combinar direção de tendência e momentum, essa abordagem mantém os traders no lado certo dos movimentos fortes. As saídas são diretas, dependendo da mudança de cor do histograma ou da inversão da inclinação da EMA.

Detalhes

  • Critérios de entrada: Sinais baseados em MACD.
  • Comprado/Vendido: Ambos os direções.
  • Critérios de saída: Sinal oposto ou stop.
  • Stops: Sim.
  • Valores padrão:
    • EmaPeriod = 13
    • MacdFastPeriod = 12
    • MacdSlowPeriod = 26
    • MacdSignalPeriod = 9
    • StopLossPercent = 2m
    • CandleType = TimeSpan.FromMinutes(5)
  • Filtros:
    • Categoria: Tendência
    • Direção: Ambos
    • Indicadores: MACD
    • Stops: Sim
    • Complexidade: Básico
    • Período: Intradiário (5m)
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
