Estratégia de Seguimento do Alligator
Implementação da estratégia Ride Alligator. O método usa três médias móveis conhecidas como o indicador Alligator. Uma posição comprada é aberta quando a linha Lips cruza acima da linha Jaws enquanto a linha Teeth está abaixo de Jaws. Uma posição vendida é aberta quando Lips cruza abaixo de Jaws e a linha Teeth está acima de Jaws. A posição aberta é protegida por um stop na linha Jaws que acompanha o movimento da linha.
Detalhes
Critérios de entrada :
Comprado: Lips > Jaws && Teeth < Jaws && previous Lips < previous Jaws
Vendido: Lips < Jaws && Teeth > Jaws && previous Lips > previous Jaws
Comprado/Vendido : Ambos
Critérios de saída :
Comprado: price <= Jaws
Vendido: price >= Jaws
Stops : Trailing stop no Alligator Jaws
Valores padrão :
AlligatorPeriod = 5
MaType = MovingAverageTypeEnum.Weighted
CandleType = TimeSpan.FromMinutes(1).TimeFrame()
Filtros :
Categoria: Seguidor de tendência
Direção: Ambos
Indicadores: Alligator
Stops: Sim
Complexidade: Básico
Período: Intradiário
Sazonalidade: Não
Redes neurais: Não
Divergência: Não
Nível de risco: Médio
