Estratégia de Tendência Escort

A Estratégia de Tendência Escort combina uma Média Móvel Ponderada (WMA) rápida e lenta com confirmação de MACD e CCI. Uma posição comprada é aberta quando a WMA rápida está acima da WMA lenta, a linha principal do MACD cruza acima da linha de sinal e o CCI supera um limiar positivo. Uma posição vendida é acionada nas condições opostas. A estratégia opcionalmente usa stop loss fixo, take profit e trailing stop.

Detalhes

  • Critérios de entrada:
    • Comprado: FastWMA > SlowWMA E MACD > Signal E CCI > +Threshold.
    • Vendido: FastWMA < SlowWMA E MACD < Signal E CCI < -Threshold.
  • Comprado/Vendido: Ambos os lados.
  • Critérios de saída:
    • Sinal de entrada oposto.
    • Stop loss, take profit ou trailing stop opcionais.
  • Stops: Sim, definidos pelo usuário.
  • Valores padrão:
    • Fast WMA = 8
    • Slow WMA = 18
    • CCI Period = 14
    • CCI Threshold = 100
    • MACD Fast EMA = 8
    • MACD Slow EMA = 18
    • Take Profit = 200
    • Stop Loss = 55
    • Trailing Stop = 35
    • Trailing Step = 3
  • Filtros:
    • Categoria: Seguidor de tendência
    • Direção: Ambos
    • Indicadores: Múltiplos
    • Stops: Sim
    • Complexidade: Moderado
    • Período: Curto prazo
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
