Artículo publicado Otras clases en la biblioteca DoEasy (Parte 67): Clase de objeto de gráfico:

En este artículo, crearemos una clase de objeto de gráfico (de un gráfico de un instrumento comercial) y modificaremos la clase de colección de objetos de señal mql5 para que cada objeto de señal guardado en la colección actualice también todos sus parámetros al actualizarse la lista.

Compilamos el asesor, abrimos los tres gráficos en el terminal e iniciamos el asesor en el primero de ellos, especificando previamente en los parámetros "trabajar solo con el símbolo y el marco temporal actuales":

Cuando llegue el primer tick, el asesor creará tres objetos de gráfico y los mostrará en el diario, además de los mensajes correspondientes sobre la inicialización de varias clases de la biblioteca y las descripciones breves de los tres objetos de gráfico creados:

Chart window EURUSD H4 ID: 131733844391938630, HWND: 918600
Chart window AUDUSD H1 ID: 131733844391938632, HWND: 1182638
Chart window GBPUSD H4 ID: 131733844391938633, HWND: 1705036

A continuación, mostrará la descripción completa de todas las propiedades del objeto de gráfico que describe el primer gráfico del terminal:
