Estrategia de Stochastic NR en Color

Esta estrategia opera usando un oscilador Stochastic con varios modos seleccionables. Cada modo define cómo se interpretan las líneas %K y %D para generar señales de compra y venta.

Modos:

  • Breakdown – largo cuando %K cruza por encima del nivel 50, corto cuando cae por debajo.
  • OscTwist – reacciona a los cambios de dirección de %K.
  • SignalTwist – reacciona a los cambios de dirección de %D.
  • OscDisposition – largo cuando %K cruza por encima de %D, corto cuando cruza por debajo.
  • SignalBreakdown – opera cuando %D cruza el nivel 50.

Las señales opuestas cierran posiciones existentes y abren nuevas en la dirección contraria. El control de riesgo se gestiona mediante niveles fijos de stop-loss y take-profit en porcentaje.

Detalles

  • Criterios de entrada:
    • Largo: Depende del modo seleccionado, ver arriba.
    • Corto: Depende del modo seleccionado, ver arriba.
  • Largo/Corto: Ambos.
  • Criterios de salida: Señal opuesta o protección de stop.
  • Stops: Sí, StopLossPercent y TakeProfitPercent.
  • Valores predeterminados:
    • KPeriod = 5
    • DPeriod = 3
    • Mode = OscDisposition
    • StopLossPercent = 2
    • TakeProfitPercent = 2
