Concepto
En el artículo anterior, creamos la clase del objeto gráfico abstracto estándar del terminal. El objeto de esta clase describirá las propiedades comunes para todos los objetos gráficos, es decir, se tratará simplemente de un cierto objeto gráfico. Para aclarar su pertenencia a un objeto gráfico real, necesitaremos heredar de él, y en la clase del objeto heredado, escribir las propiedades inherentes a ese objeto gráfico en particular. Algunas propiedades, por el contrario, serán necesarias para restringir el acceso, ya que no son parámetros de este objeto gráfico en particular, sino que están disponibles en el conjunto de propiedades del objeto abstracto.
Este concepto de construcción de objetos se adopta para casi todos los objetos de biblioteca, y las clases de objetos gráficos no serán una excepción.
Para indicar la pertenencia de los objetos creados hoy a un grupo de objetos gráficos, tomaremos el conjunto de grupos de objetos gráficos estándar del terminal y añadiremos una nueva propiedad al objeto gráfico abstracto, el grupo al que pertenece el objeto gráfico descrito por la clase heredera:
En esta ocasión, crearemos las clases de los objetos pertenecientes a los grupos "Líneas", "Canales", "Gann", "Fibonacci" y "Elliott". El resto de grupos de objetos se implementarán en el próximo artículo. El motivo es que no podemos describir todas las propiedades de estos objetos usando la funcionalidad existente del objeto gráfico abstracto. Por consiguiente, hoy implementaremos lo que ya ofrece la clase creada en el último artículo. En el próximo, añadiremos la capacidad de leer y escribir todas las propiedades de los objetos y escribir las clases del resto de grupos de objetos gráficos.
Aquí estamos hablando, por ejemplo, de los puntos de anclaje del objeto gráfico. Las propiedades almacenadas en el objeto gráfico abstracto se encuentran en las matrices de propiedades de objeto. Cada campo de estas describe una propiedad. Por ejemplo, el tiempo. Y este tiempo se toma por defecto del primer punto de anclaje del objeto gráfico. Todos los demás puntos de anclaje se pueden obtener de la función ObjectGetInteger(), especificando el índice del punto deseado con el modificador de propiedad. Y nuestra clase solo puede almacenar un valor. En consecuencia, aquí necesitaremos crear, por ejemplo, una matriz de propiedades del mismo tipo y acceder a las propiedades necesarias de la misma forma que hacemos en el modificador de propiedades.
Como el volumen del artículo no es ilimitado, dividiremos el desarrollo en varias etapas, donde alcanzaremos gradualmente una solución completa.
Mejorando las clases de la biblioteca
En el archivo \MQL5\Include\DoEasy\Defines.mqh, añadimos la enumeración de los grupos de objetos gráficos estándar:
//+------------------------------------------------------------------+ //| The list of graphical element types | //+------------------------------------------------------------------+ enum ENUM_GRAPH_ELEMENT_TYPE { GRAPH_ELEMENT_TYPE_STANDART, // Standard graphical object GRAPH_ELEMENT_TYPE_ELEMENT, // Element GRAPH_ELEMENT_TYPE_SHADOW_OBJ, // Shadow object GRAPH_ELEMENT_TYPE_FORM, // Form GRAPH_ELEMENT_TYPE_WINDOW, // Window }; //+------------------------------------------------------------------+ //| Graphical object group | //+------------------------------------------------------------------+ enum ENUM_GRAPH_OBJ_GROUP { GRAPH_OBJ_GROUP_LINES, // Lines GRAPH_OBJ_GROUP_CHANNELS, // Channels GRAPH_OBJ_GROUP_GANN, // Gann GRAPH_OBJ_GROUP_FIBO, // Fibo GRAPH_OBJ_GROUP_ELLIOTT, // Elliott GRAPH_OBJ_GROUP_SHAPES, // Shapes GRAPH_OBJ_GROUP_ARROWS, // Arrows GRAPH_OBJ_GROUP_GRAPHICAL, // Graphical objects }; //+------------------------------------------------------------------+ //| Integer properties of a standard graphical object | //+------------------------------------------------------------------+
Añadimos esta nueva propiedad a la lista de propiedades de tipo entero del objeto y aumentamos el número de propiedades de tipo entero en 1 (de 51 a 52):

El objeto gráfico tiene la propiedad de tipo entero OBJPROP_TIMEFRAMES, según la cual podemos establecer u obtener la representación del objeto en cualquiera de los marcos temporales. Los marcos temporales en que representamos el objeto se pueden definir o establecer según una combinación de banderas de visibilidad del objeto.
Para que podamos mostrar una descripción de las banderas de visibilidad establecidas para un objeto gráfico, en el archivo de funciones de servicio
\MQL5\Include\DoEasy\Services\DELib.mqh, añadiremos una función que indicará si una bandera ha sido activada o desactivada para el marco temporal solicitado:
//+------------------------------------------------------------------+ //| Return the flag of displaying the graphical | //| object on a specified chart timeframe | //+------------------------------------------------------------------+ bool IsVisibleOnTimeframe(const ENUM_TIMEFRAMES timeframe,const int flags) { if(flags==OBJ_ALL_PERIODS) return true; if(flags==OBJ_NO_PERIODS) return false; int flag=0; switch((int)timeframe) { case PERIOD_M1 : flag=0x00000001; break; case PERIOD_M2 : flag=0x00000002; break; case PERIOD_M3 : flag=0x00000004; break; case PERIOD_M4 : flag=0x00000008; break; case PERIOD_M5 : flag=0x00000010; break; case PERIOD_M6 : flag=0x00000020; break; case PERIOD_M10 : flag=0x00000040; break; case PERIOD_M12 : flag=0x00000080; break; case PERIOD_M15 : flag=0x00000100; break; case PERIOD_M20 : flag=0x00000200; break; case PERIOD_M30 : flag=0x00000400; break; case PERIOD_H1 : flag=0x00000800; break; case PERIOD_H2 : flag=0x00001000; break; case PERIOD_H3 : flag=0x00002000; break; case PERIOD_H4 : flag=0x00004000; break; case PERIOD_H6 : flag=0x00008000; break; case PERIOD_H8 : flag=0x00010000; break; case PERIOD_H12 : flag=0x00020000; break; case PERIOD_D1 : flag=0x00040000; break; case PERIOD_W1 : flag=0x00080000; break; case PERIOD_MN1 : flag=0x00100000; break; default: break; } return((flags & flag)==flag); } //+------------------------------------------------------------------+
Si en el valor transmitido a la función se han establecido las banderas de todos los marcos temporales (OBJ_ALL_PERIODS), sin ninguna duda veremos el objeto en todos los marcos temporales, y retornaremos de inmediato true sin comprobar las banderas.
Si borramos todas las banderas de todos los marcos temporales (OBJ_NO_PERIODS), el objeto estará sin duda completamente oculto para la muestra en todos los marcos temporales, así que retornamos de inmediato false.
A continuación, dependiendo del valor del marco temporal que se ha transmitido a la función, estableceremos la variable flag en el valor correspondiente, con el que luego compararemos los bits de la variable flags.
Después de obtener el valor de la máscara de bits, comparamos su valor con el valor obtenido al superponer la máscara de bits al valor de la variable flags. Y retornamos el resultado de esta comparación bit a bit. La función retornará true solo si el bit que está siendo verificado por la máscara se ha configurado en la variable flags.
Ya hemos definido los grupos de objetos gráficos. Ahora, vamos a añadir este nuevo valor a las propiedades del objeto gráfico.
En el archivo de clase del objeto básico de todos los objetos gráficos de la biblioteca \MQL5\Include\DoEasy\Objects\Graph\GBaseObj.mqh, en su sección protegida, declaramos una variable para guardar el grupo del objeto gráfico:
//+------------------------------------------------------------------+ //| Class of the base object of the library graphical objects | //+------------------------------------------------------------------+ class CGBaseObj : public CObject { private: protected: ENUM_OBJECT m_type_graph_obj; // Graphical object type ENUM_GRAPH_ELEMENT_TYPE m_type_element; // Graphical element type ENUM_GRAPH_OBJ_BELONG m_belong; // Program affiliation ENUM_GRAPH_OBJ_GROUP m_group; // Graphical object group string m_name_prefix; // Object name prefix string m_name; // Object name long m_chart_id; // Object chart ID long m_object_id; // Object ID long m_zorder; // Priority of a graphical object for receiving the mouse click event int m_subwindow; // Subwindow index int m_shift_y; // Subwindow Y coordinate shift int m_type; // Object type int m_timeframes_visible; // Visibility of an object on timeframes (a set of flags) int m_digits; // Number of decimal places in a quote bool m_visible; // Object visibility bool m_back; // "Background object" flag bool m_selected; // "Object selection" flag bool m_selectable; // "Object availability" flag bool m_hidden; // "Disable displaying the name of a graphical object in the terminal object list" flag datetime m_create_time; // Object creation time
En la sección pública, añadimos el método para establecer el grupo del objeto gráfico:
public: //--- Set the values of the class variables void SetObjectID(const long value) { this.m_object_id=value; } void SetBelong(const ENUM_GRAPH_OBJ_BELONG belong){ this.m_belong=belong; } void SetTypeGraphObject(const ENUM_OBJECT obj) { this.m_type_graph_obj=obj; } void SetTypeElement(const ENUM_GRAPH_ELEMENT_TYPE type) { this.m_type_element=type;} void SetGroup(const ENUM_GRAPH_OBJ_GROUP group){ this.m_group=group; } void SetName(const string name) { this.m_name=name; } void SetChartID(const long chart_id) { this.m_chart_id=chart_id; } void SetDigits(const int value) { this.m_digits=value; }
y el método para retornar el grupo:
//--- Return the values of class variables ENUM_GRAPH_ELEMENT_TYPE TypeGraphElement(void) const { return this.m_type_element; } ENUM_GRAPH_OBJ_BELONG Belong(void) const { return this.m_belong; } ENUM_GRAPH_OBJ_GROUP Group(void) const { return this.m_group; } ENUM_OBJECT TypeGraphObject(void) const { return this.m_type_graph_obj; } datetime TimeCreate(void) const { return this.m_create_time; } string Name(void) const { return this.m_name; } long ChartID(void) const { return this.m_chart_id; } long ObjectID(void) const { return this.m_object_id; } long Zorder(void) const { return this.m_zorder; } int SubWindow(void) const { return this.m_subwindow; } int ShiftY(void) const { return this.m_shift_y; } int VisibleOnTimeframes(void) const { return this.m_timeframes_visible; } int Digits(void) const { return this.m_digits; } bool IsBack(void) const { return this.m_back; } bool IsSelected(void) const { return this.m_selected; } bool IsSelectable(void) const { return this.m_selectable; } bool IsHidden(void) const { return this.m_hidden; } bool IsVisible(void) const { return this.m_visible; }
Eliminamos de la sección pública de la clase el método anteriormente escrito, encargado de retornar la bandera de visibilidad del objeto en el marco temporal indicado:
//--- Return the object visibility flag on a specified timeframe bool IsVisibleOnTimeframe(const ENUM_TIMEFRAMES timeframe) const { return((this.m_timeframes_visible & timeframe)==timeframe); } //--- Return the graphical object type (ENUM_OBJECT) calculated from the object type (ENUM_OBJECT_DE_TYPE) passed to the method ENUM_OBJECT GraphObjectType(const ENUM_OBJECT_DE_TYPE obj_type) const { return ENUM_OBJECT(obj_type-OBJECT_DE_TYPE_GSTD_OBJ-1); }
En primer lugar, está escrito incorrectamente (desconozco qué me impulsó a escribirlo de esta manera y no verificarlo...). En segundo lugar, ya hemos escrito una función de servicio arriba que hace lo mismo.
Y a continuación, declaramos el método que retorna la descripción del grupo de objetos gráficos:
//--- Return the graphical object type (ENUM_OBJECT) calculated from the object type (ENUM_OBJECT_DE_TYPE) passed to the method ENUM_OBJECT GraphObjectType(const ENUM_OBJECT_DE_TYPE obj_type) const { return ENUM_OBJECT(obj_type-OBJECT_DE_TYPE_GSTD_OBJ-1); } //--- Return the description of the type of the graphical object (1) type, (2) element, (3) affiliation and (4) group string TypeGraphObjectDescription(void); string TypeElementDescription(void); string BelongDescription(void); string GroupDescription(void); //--- The virtual method returning the object type virtual int Type(void) const { return this.m_type; } //--- Constructor/destructor CGBaseObj(); ~CGBaseObj(){;} }; //+------------------------------------------------------------------+
Y lo implementamos fuera del cuerpo de la clase:
//+------------------------------------------------------------------+ //| Return the description of the graphical object group | //+------------------------------------------------------------------+ string CGBaseObj::GroupDescription(void) { return ( this.Group()==GRAPH_OBJ_GROUP_LINES ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_LINES) : this.Group()==GRAPH_OBJ_GROUP_CHANNELS ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_CHANNELS) : this.Group()==GRAPH_OBJ_GROUP_GANN ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_GANN) : this.Group()==GRAPH_OBJ_GROUP_FIBO ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_FIBO) : this.Group()==GRAPH_OBJ_GROUP_ELLIOTT ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_ELLIOTT) : this.Group()==GRAPH_OBJ_GROUP_SHAPES ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_SHAPES) : this.Group()==GRAPH_OBJ_GROUP_ARROWS ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_ARROWS) : this.Group()==GRAPH_OBJ_GROUP_GRAPHICAL? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_GRAPHICAL) : "Unknown" ); } //+------------------------------------------------------------------+
Aquí, todo resulta muy sencillo: dependiendo del valor escrito en la variable m_group, y retornado por el método Group(), retornamos el mensaje de texto correspondiente.
Vamos a mejorar la clase de objeto gráfico abstracto en el archivo \MQL5\Include\DoEasy\Objects\Graph\Standart\GStdGraphObj.mqh.
Como algunas propiedades de los objetos serán diferentes para objetos gráficos distintos, la implementación de los métodos que retornen estas propiedades también debería ser diferente. Para hacer esto, crearemos métodos virtuales para dichas propiedades con una implementación común en la clase de objeto gráfico abstracto, mientras que para los objetos heredados, anularemos esta implementación en la clase heredada.
En la sección pública de la clase, escribimos tres métodos virtuales que retornan la descripción del tipo de objeto gráfico y la descripción del precio y el tiempo del primer punto de anclaje del objeto:
//--- Display the description of the object properties in the journal (full_prop=true - all properties, false - supported ones only - implemented in descendant classes) virtual void Print(const bool full_prop=false,const bool dash=false); //--- Display a short description of the object in the journal virtual void PrintShort(const bool dash=false,const bool symbol=false); //--- Return the object short name virtual string Header(const bool symbol=false); //--- Return the description of the graphical object (1) type (ENUM_OBJECT), price coordinate (2) and (3) time virtual string TypeDescription(void) const { return CMessage::Text(MSG_GRAPH_STD_OBJ_ANY); } virtual string PriceDescription(void) const { return ::DoubleToString(this.GetProperty(GRAPH_OBJ_PROP_PRICE),this.m_digits); } virtual string TimeDescription(void) const { return ::TimeToString(this.GetProperty(GRAPH_OBJ_PROP_TIME),TIME_DATE|TIME_MINUTES); } //--- Compare CGStdGraphObj objects by a specified property (to sort the list by an object property) virtual int Compare(const CObject *node,const int mode=0) const; //--- Compare CGStdGraphObj objects with each other by all properties (to search for equal objects) bool IsEqual(CGStdGraphObj* compared_req) const; //--- Default constructor
En los objetos heredados, anularemos estos métodos para mostrar información sobre un objeto gráfico específico descrito por la clase heredada.
En el constructor paramétrico protegido de la clase, añadimos un nuevo parámetro formal, el grupo del objeto gráfico estándar, mientras que en el constructor predeterminado, escribimos directamente el valor para el grupo, igual a -1:

Al final de la lista con los métodos para el acceso simplificado a las propiedades de la clase, escribimos los métodos que retornan las banderas de visibilidad del objeto en el marco temporal indicado. Cada periodo tiene su propio método. Y declaramos el método que retorna la descripción de la visibilidad del objeto en todos los marcos temporales:

En el método que retorna la descripción de una propiedad de tipo real del objeto, también sustituimos la muestra de la descripción del precio del punto de anclaje por la muestra del método:

En el método que retorna la descripción de una propiedad string del objeto, añadimos la muestra de las comillas en las que se incluirán las propiedades string mostradas. Para describir las pistas emergentes, mostraremos un mensaje que indique que la información sobre las pistas es generada automáticamente por el terminal si no está configurada y no es un símbolo de control "\n", lo cual deshabilita la información sobre la pista emergente:

Método que retorna la descripción de la visibilidad del objeto en los marcos temporales:
//+------------------------------------------------------------------+ //| Return the description of the object visibility on timeframes | //+------------------------------------------------------------------+ string CGStdGraphObj::VisibleOnTimeframeDescription(void) { string res=""; int flags=(int)this.GetProperty(GRAPH_OBJ_PROP_TIMEFRAMES); if(flags==OBJ_NO_PERIODS) return CMessage::Text(MSG_LIB_TEXT_OBJ_NO_PERIODS); if(flags==OBJ_ALL_PERIODS) return CMessage::Text(MSG_LIB_TEXT_OBJ_ALL_PERIODS); for(int i=1;i<=21;i++) { ENUM_TIMEFRAMES timeframe=TimeframeByEnumIndex((uchar)i); if(!IsVisibleOnTimeframe(timeframe,flags)) continue; res+=TimeframeDescription(timeframe)+", "; } ::StringSetCharacter(res,::StringLen(res)-2,' '); ::StringTrimRight(res); return res; } //+------------------------------------------------------------------+
Aquí, obtenemos las banderas de bits de la visibilidad del objeto en los marcos temporales desde la propiedad del objeto.
Si no se ha establecido ninguna de las banderas, retornamos un mensaje que indique que el objeto no es visible en ninguno de los marcos temporales.
Si, por el contrario, se establecen todas las banderas de todos los marcos temporales, retornaremos un mensaje que indique que el objeto es visible en todos los marcos temporales.
Si solo se establecen algunas de las banderas, entonces, en un ciclo de 1 a 21 inclusive, obtendremos el marco temporal según el índice usando la función de servicio TimeframeByEnumIndex(), que ya escribimos hace mucho tiempo, y que se encuentra en el archivo de funciones de servicio.
Si el objeto es invisible en el marco temporal obtenido, pasaremos a la siguiente iteración para obtener el siguiente marco temporal.
Si el objeto es visible, añadiremos su descripción breve al valor de la variable res con una coma y un espacio al final.
Después del ciclo, al final de la línea resultante, sustituiremos por un espacio el carácter de coma añadido a la última iteración del ciclo y eliminaremos todos los espacios y caracteres de control a la derecha de la línea. Retornamos desde el método la línea resultante.
Ya hemos completado todas las modificaciones de las clases. Vamos a comenzar a crear las clases que heredarán de la clase de objeto gráfico abstracto.
Clases herederas del objeto gráfico abstracto
Hoy, vamos a crear las clases de varios grupos de objetos gráficos: "Líneas", "Canales", "Gann", "Fibonacci" y "Elliott".
En la carpeta \MQL5\Include\DoEasy\Objects\Graph\Standart\, crearemos el nuevo archivo GStdHLineObj.mqh de la clase de línea horizontal StdHLineObj.
La clase debe heredar del objeto gráfico abstracto, y el archivo de clase principal debe estar conectado a la clase generada:
//+------------------------------------------------------------------+ //| GStdHLineObj.mqh | //| Copyright 2021, MetaQuotes Ltd. | //| https://mql5.com/en/users/artmedia70 | //+------------------------------------------------------------------+ #property copyright "Copyright 2021, MetaQuotes Ltd." #property link "https://mql5.com/en/users/artmedia70" #property link "https://mql5.com/en/users/artmedia70" #property version "1.00" //+------------------------------------------------------------------+ //| Include files | //+------------------------------------------------------------------+ #include "GStdGraphObj.mqh" //+------------------------------------------------------------------+ //| "Horizontal line" graphical object | //+------------------------------------------------------------------+ class CGStdHLineObj : public CGStdGraphObj { }
En la sección pública de la clase, añadimos un constructor, declaramos tres métodos que retornan las banderas de soporte de propiedades por parte del objeto y los métodos para mostrar las descripciones del objeto y sus propiedades:
//+------------------------------------------------------------------+ //| "Horizontal line" graphical object | //+------------------------------------------------------------------+ class CGStdHLineObj : public CGStdGraphObj { private: public: //--- Constructor CGStdHLineObj(const long chart_id,const string name) : CGStdGraphObj(OBJECT_DE_TYPE_GSTD_HLINE,GRAPH_OBJ_BELONG_NO_PROGRAM,GRAPH_OBJ_GROUP_LINES,chart_id,name) {} //--- Supported object properties (1) real, (2) integer virtual bool SupportProperty(ENUM_GRAPH_OBJ_PROP_DOUBLE property); virtual bool SupportProperty(ENUM_GRAPH_OBJ_PROP_INTEGER property); virtual bool SupportProperty(ENUM_GRAPH_OBJ_PROP_STRING property); //--- Display a short description of the object in the journal virtual void PrintShort(const bool dash=false,const bool symbol=false); //--- Return the object short name virtual string Header(const bool symbol=false); //--- Return the description of the graphical object price (1) type (ENUM_OBJECT) and (2) price coordinate virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); } virtual string TimeDescription(void) const { return ::TimeToString(this.GetProperty(GRAPH_OBJ_PROP_TIME),TIME_DATE|TIME_MINUTES)+" "+ CMessage::Text(MSG_GRAPH_OBJ_TEXT_CLICK_COORD); } }; //+------------------------------------------------------------------+
El propósito de los métodos debería quedar claro a partir de sus nombres, y ya hemos analizado muchas veces métodos similares en otras clases.
En el constructor de la clase, en su lista de inicialización, transmitimos al constructor paramétrico privado de la clase padre el tipo de objeto (línea horizontal), la pertenencia (no pertenece al programa), el grupo de objetos (líneas) y los valores del identificador del gráfico y el nombre del objeto transmitidos al constructor de la clase:
CGStdHLineObj(const long chart_id,const string name) : CGStdGraphObj(OBJECT_DE_TYPE_GSTD_HLINE,GRAPH_OBJ_BELONG_NO_PROGRAM,GRAPH_OBJ_GROUP_LINES,chart_id,name) {}
El método virtual TypeDescription() retorna la descripción del tipo de objeto gráfico retornado por la función de servicio StdGraphObjectTypeDescription(), que escribimos antes, y a la cual transmitimos el tipo de objeto (línea horizontal):
virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); }
El método virtual TimeDescription(), que retorna la descripción del tiempo, muestra el tiempo registrado en las propiedades de la línea horizontal. Pero, como la línea horizontal no tiene anclaje temporal, en esta propiedad introduciremos la coordenada del cursor del ratón al clicar en el gráfico mientras colocamos el objeto. Se mostrará un mensaje adicional sobre ello en la descripción de la hora mostrada en el diario:
virtual string TimeDescription(void) const { return ::TimeToString(this.GetProperty(GRAPH_OBJ_PROP_TIME),TIME_DATE|TIME_MINUTES)+" "+ CMessage::Text(MSG_GRAPH_OBJ_TEXT_CLICK_COORD); }
Métodos que retornan las banderas de soporte por parte del objeto de propiedades de tipo entero, real y string:
//+------------------------------------------------------------------+ //| Return 'true' if an object supports a passed | //| integer property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CGStdHLineObj::SupportProperty(ENUM_GRAPH_OBJ_PROP_INTEGER property) { switch((int)property) { //--- Supported properties case GRAPH_OBJ_PROP_ID : case GRAPH_OBJ_PROP_TYPE : case GRAPH_OBJ_PROP_ELEMENT_TYPE : case GRAPH_OBJ_PROP_GROUP : case GRAPH_OBJ_PROP_BELONG : case GRAPH_OBJ_PROP_CHART_ID : case GRAPH_OBJ_PROP_WND_NUM : case GRAPH_OBJ_PROP_NUM : case GRAPH_OBJ_PROP_CREATETIME : case GRAPH_OBJ_PROP_TIMEFRAMES : case GRAPH_OBJ_PROP_BACK : case GRAPH_OBJ_PROP_ZORDER : case GRAPH_OBJ_PROP_HIDDEN : case GRAPH_OBJ_PROP_SELECTED : case GRAPH_OBJ_PROP_SELECTABLE : case GRAPH_OBJ_PROP_TIME : case GRAPH_OBJ_PROP_COLOR : case GRAPH_OBJ_PROP_STYLE : case GRAPH_OBJ_PROP_WIDTH : return true; //--- Other properties are not supported //--- Default is 'false' default: break; } return false; } //+------------------------------------------------------------------+ //| Return 'true' if an object supports a passed | //| real property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CGStdHLineObj::SupportProperty(ENUM_GRAPH_OBJ_PROP_DOUBLE property) { switch((int)property) { //--- Supported properties case GRAPH_OBJ_PROP_PRICE : return true; //--- Other properties are not supported //--- Default is 'false' default: break; } return false; } //+------------------------------------------------------------------+ //| Return 'true' if an object supports a passed | //| string property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CGStdHLineObj::SupportProperty(ENUM_GRAPH_OBJ_PROP_STRING property) { switch((int)property) { //--- Supported properties case GRAPH_OBJ_PROP_NAME : case GRAPH_OBJ_PROP_TEXT : case GRAPH_OBJ_PROP_TOOLTIP : return true; //--- Other properties are not supported //--- Default is 'false' default: break; } return false; } //+------------------------------------------------------------------+
Transmitimos la propiedad a cada método, y después, si esta propiedad se encuentra en la lista de propiedades soportadas, retornaremos true, de lo contrario, false.
Para cada clase, las listas de propiedades soportadas serán diferentes; después de todo, cada uno de los objetos gráficos tiene su propio conjunto de propiedades. Asimismo, los constructores de clases también serán únicos para cada uno de los objetos heredados del objeto gráfico abstracto.
Métodos que retornan el nombre breve del objeto y muestran la descripción breve del mismo:
//+------------------------------------------------------------------+ //| Return the object short name | //+------------------------------------------------------------------+ string CGStdHLineObj::Header(const bool symbol=false) { return this.TypeDescription(); } //+------------------------------------------------------------------+ //| Display a short description of the object in the journal | //+------------------------------------------------------------------+ void CGStdHLineObj::PrintShort(const bool dash=false,const bool symbol=false) { ::Print ( this.Header(symbol)," \"",CGBaseObj::Name(),"\": ID ",(string)this.GetProperty(GRAPH_OBJ_PROP_ID), " ",::TimeToString(CGBaseObj::TimeCreate(),TIME_DATE|TIME_MINUTES|TIME_SECONDS) ); } //+------------------------------------------------------------------+
Estos métodos (1) retornan una línea que describe el tipo de objeto gráfico y (2) muestran en el diario el tipo de objeto gráfico, su nombre, el identificador asignado al objeto al crear este y la hora en que se ha creado.
Todas las demás clases que describen los objetos gráficos de diferentes tipos incluidos en distintos grupos serán estudiadas en su totalidad como un análisis independiente.

Estos son todos los objetos de las clases herederas del objeto gráfico abstracto planeados para hoy. Como podemos ver, son idénticos entre sí, pero difieren en los tipos de propiedades soportadas. Esto significa que cada uno de estos objetos tendrá solo aquellas propiedades que le sean inherentes. Y la ventaja aquí no está solo en la muestra de estos datos en el diario, sino también en el hecho de que la búsqueda y la clasificación de objetos en la biblioteca tiene en consideración las banderas de soporte de una propiedad particular por parte del objeto. Por consiguiente, al clasificar todos los objetos gráficos de la colección, por ejemplo, según el ángulo, los objetos que no tengan ningún ángulo no podrán entrar en la lista final; esta propiedad no será compatible con ellos.
Dejaremos todas las clases anteriores para un análisis independiente.
Ahora, necesitamos modificar la clase para gestionar los objetos gráficos ubicados en el archivo de la clase de colección de objetos gráficos en la dirección \MQL5\Include\DoEasy\Collections\GraphElementsCollection.mqh.
Necesitamos asegurarnos de que, dependiendo del objeto gráfico añadido al gráfico, se cree una nueva instancia de la clase de objeto gráfico estándar a partir de las que hemos creado aquí. Vamos a añadir las mejoras necesarias al archivo.
Incluimos los archivos de todas las clases creadas hoy en el archivo de la clase de colección de objetos gráficos (en lugar del archivo GStdGraphObj.mqh previamente incluido) y declaramos un método público para crear un nuevo objeto que describa el objeto gráfico añadido al gráfico:

En el método que verifica los cambios en el número de objetos en el gráfico, introducimos en la clase de gestión de objetos gráficos ciertas mejoras en el bloque de código encargado de crear un nuevo objeto que describe un objeto gráfico añadido al gráfico:
//+------------------------------------------------------------------+ //| CChartObjectsControl Check objects on a chart | //+------------------------------------------------------------------+ void CChartObjectsControl::Refresh(void) { //--- Graphical objects on the chart this.m_total_objects=::ObjectsTotal(this.ChartID()); this.m_delta_graph_obj=this.m_total_objects-this.m_last_objects; //--- If the number of objects has changed if(this.m_delta_graph_obj!=0) { //--- Create the string and display it in the journal with the chart ID, its symbol and timeframe string txt=", "+(m_delta_graph_obj>0 ?

Antes, aquí creamos un nuevo objeto gráfico abstracto. Ahora, vamos a crear un objeto del tipo apropiado usando las clases herederas creadas hoy. Después de crear el objeto con éxito, le añadiremos la propiedad de pertenencia (no pertenece al programa), y en lugar de mostrar la descripción breve del objeto creado, mostraremos en el diario la descripción completa de todas sus propiedades.
Para seleccionar el objeto que necesitamos crear, deberemos usar el método que crea un nuevo objeto gráfico estándar:
//+------------------------------------------------------------------+ //| Create a new standard graphical object | //+------------------------------------------------------------------+ CGStdGraphObj *CChartObjectsControl::CreateNewGraphObj(const ENUM_OBJECT obj_type,const long chart_id,const string name) { CGStdGraphObj *obj=NULL; switch((int)obj_type) { //--- Lines case OBJ_VLINE : return new CGStdVLineObj(chart_id,name); case OBJ_HLINE : return new CGStdHLineObj(chart_id,name); case OBJ_TREND : return new CGStdTrendObj(chart_id,name); case OBJ_TRENDBYANGLE : return new CGStdTrendByAngleObj(chart_id,name); case OBJ_CYCLES : return new CGStdCyclesObj(chart_id,name); case OBJ_ARROWED_LINE : return new CGStdArrowedLineObj(chart_id,name); //--- Channels case OBJ_CHANNEL : return new CGStdChannelObj(chart_id,name); case OBJ_STDDEVCHANNEL : return new CGStdStdDevChannelObj(chart_id,name); case OBJ_REGRESSION : return new CGStdRegressionObj(chart_id,name); case OBJ_PITCHFORK : return new CGStdPitchforkObj(chart_id,name); //--- Gann case OBJ_GANNLINE : return new CGStdGannLineObj(chart_id,name); case OBJ_GANNFAN : return new CGStdGannFanObj(chart_id,name); case OBJ_GANNGRID : return new CGStdGannGridObj(chart_id,name); //--- Fibo case OBJ_FIBO : return new CGStdFiboObj(chart_id,name); case OBJ_FIBOTIMES : return new CGStdFiboTimesObj(chart_id,name); case OBJ_FIBOFAN : return new CGStdFiboFanObj(chart_id,name); case OBJ_FIBOARC : return new CGStdFiboArcObj(chart_id,name); case OBJ_FIBOCHANNEL : return new CGStdFiboChannelObj(chart_id,name); case OBJ_EXPANSION : return new CGStdExpansionObj(chart_id,name); //--- Elliott case OBJ_ELLIOTWAVE5 : return new CGStdElliotWave5Obj(chart_id,name); case OBJ_ELLIOTWAVE3 : return new CGStdElliotWave3Obj(chart_id,name); /* //--- Shapes case OBJ_RECTANGLE : return new CGStdRectangleObj(chart_id,name); case OBJ_TRIANGLE : return new CGStdTriangleObj(chart_id,name); case OBJ_ELLIPSE : return new CGStdEllipseObj(chart_id,name); //--- Arrows case OBJ_ARROW_THUMB_UP : return new CGStdArrowThumbUpObj(chart_id,name); case OBJ_ARROW_THUMB_DOWN : return new CGStdArrowThumbDownObj(chart_id,name); case OBJ_ARROW_UP : return new CGStdArrowUpObj(chart_id,name); case OBJ_ARROW_DOWN : return new CGStdArrowDownObj(chart_id,name); case OBJ_ARROW_STOP : return new CGStdArrowStopObj(chart_id,name); case OBJ_ARROW_CHECK : return new CGStdArrowCheckObj(chart_id,name); case OBJ_ARROW_LEFT_PRICE : return new CGStdArrowLeftPriceObj(chart_id,name); case OBJ_ARROW_RIGHT_PRICE : return new CGStdArrowRightPriceObj(chart_id,name); case OBJ_ARROW_BUY : return new CGStdArrowBuyObj(chart_id,name); case OBJ_ARROW_SELL : return new CGStdArrowSellObj(chart_id,name); case OBJ_ARROW : return new CGStdArrowObj(chart_id,name); //--- Graphical objects case OBJ_TEXT : return new CGStdTextObj(chart_id,name); case OBJ_LABEL : return new CGStdLabelObj(chart_id,name); case OBJ_BUTTON : return new CGStdButtonObj(chart_id,name); case OBJ_CHART : return new CGStdChartObj(chart_id,name); case OBJ_BITMAP : return new CGStdBitmapObj(chart_id,name); case OBJ_BITMAP_LABEL : return new CGStdBitmapLabelObj(chart_id,name); case OBJ_EDIT : return new CGStdEditObj(chart_id,name); case OBJ_EVENT : return new CGStdEventObj(chart_id,name); case OBJ_RECTANGLE_LABEL : return new CGStdRectangleLabelObj(chart_id,name); */ default : return NULL; } } //+------------------------------------------------------------------+
Aquí, todo es simple: solo tenemos que transmitir al método el tipo de objeto que se debe crear, el identificador del gráfico al que se ha añadido el objeto gráfico y el nombre del nuevo objeto gráfico. Además, dependiendo del tipo de objeto gráfico transmido al método, y usando el operador new, crearemos un nuevo objeto de la clase correspondiente heredada del objeto gráfico abstracto y retornaremos inmediatamente el resultado de la creación de este nuevo objeto.
El método retornará un puntero al objeto recién creado, o NULL, si se da cualquier error al crear el objeto. Como podemos ver, todavía no se han creado todos los objetos. El resto se implementará en el próximo artículo, junto con las modificaciones que añadiremos definitivamente a las clases creadas hoy. Vamos a necesitar acceder a todas las propiedades de todos los puntos de apoyo del objeto, y no al primero de todos, como hemos hecho en esta etapa.
Ya tenemos todo listo para hacer la prueba.
Simulación
Para la simulación, vamos a tomar el asesor del artículo anterior y guardarlo en la nueva carpeta \MQL5\Experts\TestDoEasy\Part84\ con el nuevo nombre TestDoEasyPart84.mq5.
En esta etapa, no será necesario que realicemos ningún cambio en el asesor. Pero, para mantener el orden, lo guardamos en la carpeta de artículos correspondiente del terminal.
Compilamos el asesor, lo ejecutamos en el terminal y añadimos al gráfico algunos objetos gráficos.
El diario mostrará las descripciones completas de todas las propiedades de los objetos añadidos al gráfico:
¿Qué es lo próximo?
En el próximo artículo, continuaremos desarrollando las clases herederas del objeto gráfico abstracto y la clase de colección de objetos gráficos de la biblioteca.
Más abajo se adjuntan todos los archivos de la versión actual de la biblioteca y el archivo del asesor de prueba para MQL5. Podrá descargarlo todo y ponerlo a prueba por sí mismo.
Si tiene preguntas, observaciones o sugerencias, podrá concretarlas en los comentarios al artículo.

Gestionando el Horario (Parte 2): Funciones
Determinando la compensación del bróker y la hora GMT de forma automática. En lugar de pedir ayuda a su bróker, de quien probablemente recibirá una respuesta insuficiente (quién estaría dispuesto a explicar dónde se ha metido la hora faltante), simplemente nos fijaremos en cómo estos calculan sus precios en las semanas de cambio horario, pero evitando engorrosos cálculos manuales: un programa se encargará de ello, después de todo, ¿para qué tenemos un PC?
Gestionando el Horario (Parte 1): Fundamentos
Funciones y fragmentos de código que simplifican y aclaran el manejo del tiempo, la diferencia con el bróker y los cambios en el horario de verano o invierno. La sincronización precisa puede ser un elemento crucial en el trading. A la hora actual, ¿la bolsa de valores de Londres o Nueva York está ya abierta o sigue cerrada? ¿Cuándo comienza y finaliza el horario comercial para el trading en Fórex? Para un tráder que comercia de forma manual y en vivo, esto no supone un gran problema.
