Solo Largos: Ruptura del Rango de Apertura (ORB) con Puntos Pivote

La estrategia compra cuando el precio rompe por encima del máximo del rango de apertura y la primera resistencia (R1) de los pivotes diarios está por encima de ese máximo. Un stop trailing sigue los niveles de pivote.

Detalles

  • Criterios de entrada:
    • Tras el rango de apertura, entrar largo en una ruptura por encima del máximo de sesión si R1 es más alto.
  • Largo/Corto: Solo largos
  • Criterios de salida:
    • Stop trailing ajustado a los niveles de pivote y cierre diario.
  • Stops: Sí
  • Valores predeterminados:
    • RangeMinutes = 15
    • SessionStart = 09:30
    • MaxTradesPerDay = 1
    • StopLossPercent = 3
    • InitialSlType = Percentage
  • Filtros:
    • Categoría: Ruptura
    • Dirección: Largo
