Estrategia de Flujo de Tendencia Adaptativa

La estrategia de Flujo de Tendencia Adaptativa construye un canal basado en volatilidad a partir de EMA rápidas y lentas del precio típico. Cuando el precio cruza los límites del canal, la tendencia interna cambia. Las posiciones largas se abren cuando la tendencia gira hacia arriba y los filtros opcionales de SMA y MACD lo confirman. Las posiciones se cierran cuando la tendencia se invierte hacia abajo.

Detalles

  • Criterios de entrada:
    • La tendencia cambia de bajista a alcista y los filtros lo confirman.
  • Largo/Corto: Solo largos.
  • Criterios de salida:
    • La tendencia cambia de alcista a bajista.
  • Stops: Ninguno.
  • Valores predeterminados:
    • Length = 2
    • SmoothLength = 2
    • Sensitivity = 2.0
    • UseSmaFilter = true
    • SmaLength = 4
    • UseMacdFilter = true
    • MacdFastLength = 2
    • MacdSlowLength = 7
    • MacdSignalLength = 2
  • Filtros:
    • Categoría: Seguimiento de tendencia
    • Dirección: Largo
    • Indicadores: EMA, SMA, MACD, Standard Deviation
    • Stops: No
    • Complejidad: Moderado
    • Marco temporal: Cualquiera
    • Estacionalidad: No
    • Redes neuronales: No
