CCI Slope Estrategia de Reversión a la Media

La estrategia CCI Slope de Reversión a la Media se centra en lecturas extremas del CCI para aprovechar la reversión. Las desviaciones amplias del nivel típico raramente perduran.

Las operaciones se activan cuando el indicador se aleja mucho de su media y luego comienza a revertirse. Tanto las configuraciones largas como las cortas incluyen un stop de protección.

Adecuada para traders de swing que esperan oscilaciones, la estrategia cierra la posición una vez que el CCI regresa al equilibrio. Parámetro inicial CciPeriod = 20.

Detalles

  • Criterios de entrada: El indicador cruza de vuelta hacia la media.
  • Largo/Corto: Ambas direcciones.
  • Criterios de salida: El indicador revierte al promedio.
  • Stops: Sí.
  • Valores predeterminados:
    • CciPeriod = 20
    • SlopeLookback = 20
    • ThresholdMultiplier = 2m
    • StopLossPercent = 2m
    • CandleType = TimeSpan.FromMinutes(5)
  • Filtros:
    • Categoría: Reversión a la media
    • Dirección: Ambos
    • Indicadores: CCI
    • Stops: Sí
    • Complejidad: Intermedio
    • Marco temporal: Corto plazo
    • Estacionalidad: No
