Estratégia ADX de Momentum de Sentimento

A estratégia ADX Sentiment Momentum é construída em torno do momentum de sentimento do ADX.

Os sinais são acionados quando seus indicadores confirmam mudanças de momentum em dados intradiários (5m). Isso torna o método adequado para traders ativos.

Os stops dependem de múltiplos de ATR e fatores como AdxPeriod, AdxThreshold. Ajuste esses valores padrão para equilibrar risco e recompensa.

Detalhes

  • Critérios de entrada: ver implementação para condições de indicadores.
  • Comprado/Vendido: Ambos as direções.
  • Critérios de saída: sinal oposto ou lógica de stop.
  • Stops: Sim, usando cálculos baseados em indicadores.
  • Valores padrão:
    • AdxPeriod = 14
    • AdxThreshold = 25m
    • SentimentPeriod = 5
    • StopLoss = 2m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame()
  • Filtros:
    • Categoria: Seguidor de tendência
    • Direção: Ambos
    • Indicadores: Múltiplos indicadores
    • Stops: Sim
    • Complexidade: Intermediário
    • Período: Intradiário (5m)
    • Sazonalidade: Não
    • Redes neurais: Não
    • Divergência: Não
    • Nível de risco: Médio
