no funciona, lamentablemente.

Se introducen en la clase. Tengo que añadirlos como una función separada .... ?

No sé cómo hacerlos. He intentado encontrar ejemplos de cómo añadir clases de arrastre existentes, pero no he encontrado ninguno.

No se puede copiar SIN pensar. Mira de nuevo la fuente original.

Ejemplo de un EA: en una cuenta hadge abrimos dos posiciones opuestas a la vez - sin ningún tipo de stop.

Hay dos parámetros en la configuración del EA:

  • TrailingStop (en pips)
  • TrailingStep (en pips)
TrailingStep protege contra las modificaciones demasiado frecuentes:

¡¡¡Gracias, ha funcionado aunque no lo haya hecho la primera vez!!!
Me pregunto si hay tres máximos (mínimos), entonces el índice de cuál dará ArrayMaximum(ArrayMinimum)?
Vladimir:
Me pregunto, si hay tres máximos (mínimos), ¿cuál será el índice ArrayMaximum (ArrayMinimum)?
El máximo (mínimo). Esta función no tiene más de un valor de salida.
Vitalie Postolache:
El valor máximo (mínimo). Esta función no tiene más de un valor de salida.
Eso es lo que pido. Hay cinco números en la matriz: 1.1012 1.1013 1.1013 1.1012, ¿cuál de los elementos considerará la función como máximo? Ninguno, hay tres igualmente grandes. Opciones de respuesta: la primera encontrada, la última encontrada, cualquiera de las máximas. Si quieres, puedes proponer más opciones. La elección debería estar reflejada en la descripción de la función en la ayuda (documentación), pero no la he encontrado.
