Estratégia ForexLine
A estratégia ForexLine é um sistema seguidor de tendência derivado do indicador MetaTrader "ForexLine". Ela aplica dois estágios de médias móveis ponderadas ao preço para construir linhas rápidas e lentas. Os cruzamentos entre essas linhas com dupla suavização são usados para determinar os sinais de entrada.
A estratégia compra quando a linha rápida cruza acima da linha lenta e vende quando a linha rápida cruza abaixo da linha lenta. Cada média móvel usa um processo de suavização em dois passos que ajuda a filtrar o ruído de mercado.
Detalhes
- Critérios de entrada:
- Comprado: A WMA duplamente suavizada rápida cruza acima da WMA duplamente suavizada lenta.
- Vendido: A WMA duplamente suavizada rápida cruza abaixo da WMA duplamente suavizada lenta.
- Comprado/Vendido: Ambas as direções.
- Critérios de saída:
- O cruzamento oposto fecha a posição existente.
- Stops: Não incluídos; podem ser adicionados externamente.
- Valores padrão:
FastLength1= 5FastLength2= 10SlowLength1= 20SlowLength2= 20CandleType= período de 8 horas
- Filtros:
- Categoria: Seguidor de tendência
- Direção: Ambos
- Indicadores: Médias móveis ponderadas
- Stops: Não
- Complexidade: Moderado
- Período: Médio prazo
- Sazonalidade: Não
- Redes neurais: Não
- Divergência: Não
- Nível de risco: Médio
