Ideia
No último artigo criamos uma classe do objeto gráfico abstrato padrão do terminal. O objeto deste tipo de classe descreve propriedades comuns a todos os objetos gráficos, isto é, ele é apenas um tipo de objeto gráfico. Para entender se pertence a um objeto gráfico real, precisamos gerar herança a partir dele, já na classe do objeto herdeiro precisamos escrever as propriedades que são específicas do objeto gráfico em particular. Por outra parte, algumas propriedades restringem o acesso a ele, uma vez que não são parâmetros deste objeto gráfico particular, mas estão disponíveis no conjunto de propriedades do objeto abstrato.
Esta abordagem para construir objetos é aceito por quase todos os objetos de biblioteca, e as classes dos objetos gráficos não são exceção.
Para especificar se os objetos criados hoje pertencem ao grupo de objetos gráficos, tomaremos um conjunto de grupos de objetos gráficos padrão a partir do terminal e adicionaremos uma nova propriedade ao objeto gráfico abstrato, isto é, o grupo ao qual pertence o objeto gráfico descrito pela classe herdeira:
Hoje vamos criar classes de objetos pertencentes aos grupos Lines, Channels, Gann, Fibonacci e Elliott. Faremos o resto dos grupos de objetos no próximo artigo. A razão é que não podemos descrever todas as propriedades desses objetos usando a funcionalidade existente de objeto gráfico abstrato. Por isso, hoje vamos fazer o que a classe criada no artigo anterior já oferece e no próximo artigo vamos acrescentar a capacidade de ler e escrever todas as propriedades dos objetos, e vamos escrever classes para os outros grupos de objetos gráficos.
Aqui estamos falando, por exemplo, dos pontos de ancoragem de um objeto gráfico. As propriedades armazenadas no objeto gráfico abstrato estão nas matrizes de propriedades do objeto, onde cada campo de matriz descreve uma propriedade, como o tempo. Esse tempo é obtido por padrão a partir do primeiro ponto de ancoragem do objeto gráfico. Todos os outros pontos de ancoragem podem ser obtidos a partir da função ObjectGetInteger() especificando o índice do ponto desejado com o modificador de propriedade. Nossa classe pode armazenar apenas um valor. Em consequência, aqui precisaremos criar, por exemplo, uma matriz de propriedades do mesmo tipo e acessar as propriedades necessárias da mesma forma que com o modificador de propriedade.
Como a extensão do artigo é incerta, vamos dividir o trabalho em várias fases, e assim, gradualmente, chegaremos a uma solução final.
Aprimorando as classes da biblioteca
No arquivo MQL5\Include\DoEasy\Data.mqh adicionamos as enumerações de grupos de objetos gráficos padrão:
//+------------------------------------------------------------------+ //| 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 | //+------------------------------------------------------------------+
Adicionar esta nova propriedade à lista de propriedades inteiras do objeto e aumentamos o número de propriedades inteiras em 1 (de 51 para 52):

O objeto gráfico tem a propriedade inteira OBJPROP_TIMEFRAMES que permite definir ou obter a exibição do objeto em qualquer um dos períodos gráficos. Os períodos gráficos em que o objeto é exibido podem ser definidos ou configurados através de uma combinação de sinalizadores de visibilidade do objeto.
Para que possamos exibir uma descrição do sinalizadores de visibilidade definidas para o objeto gráfico, no arquivo de funções de serviço
\MQL5\Include\DoEasy\Services\DELib.mqh escrevemos uma função que retorna se o sinalizador está definido ou desmarcado para o período gráfico 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); } //+------------------------------------------------------------------+
Se no valor passado para a função os sinalizadores de todos os períodos gráficos estiverem definidos (OBJ_ALL_PERIODS), veremos o objeto em todos os períodos gráficos, e imediatamente retornamos true sem verificação de sinalizadores.
Se os sinalizadores de todos os períodos gráficos (OBJ_NO_PERIODS), o objeto será completamente oculto em todos os períodos gráficos, logo retornamos false.
Em seguida, dependendo do valor de período gráfico para a função, definimos como variável flag os valores respectivos que usaremos depois para comparar os bits da variável flags.
Depois de obter o valor da máscara de bits, comparamos com o valor obtido colocando a máscara de bits sobre o valor da variável flags. E retorna o resultado desta comparação bit a bit. A função retorna true só se na variável flags estiver definido o bit a ser verificado a nível de máscara.
Definimos grupos de objetos gráficos. Agora vamos adicionar este novo valor às propriedades do objeto gráfico.
No arquivo da classe do objeto base de todos os objetos gráficos da biblioteca \MQL5\Include\DoEasy\Objects\Graph\GBaseObj.mqh, na sua seção protegida, declaramos uma variável para armazenar o grupo do 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
Na seção pública vamos escrever um método para definir o grupo do 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; }
e o método para retornar o 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; }
O método previamente escrito que retorna o sinalizador de visibilidade do objeto no período gráfico especificado será retirado da seção pública da classe:
//--- 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); }
Primeiro, não está escrito corretamente (não sei o que me levou a escrevê-lo dessa maneira e não verificá-lo...), segundo, já escrevemos uma função de serviço acima que faz a mesma coisa.
Em seguida, declaramos um método que retorna uma descrição do grupo de objeto gráfico:
//--- 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(){;} }; //+------------------------------------------------------------------+
Fora do corpo da classe, vamos escrever sua implementação:
//+------------------------------------------------------------------+ //| 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" ); } //+------------------------------------------------------------------+
Aqui, basta retornar a mensagem de texto correspondente, dependendo do valor armazenado na variável m_group e retornado pelo método Group().
Modificamos a classe do objeto gráfico abstrato no arquivo \MQL5\Include\DoEasy\Objects\Graph\Standart\GStdGraphObj.mqh.
Como algumas propriedades dos objetos serão diferentes para diferentes objetos gráficos, a implementação dos métodos que devolvem essas propriedades também deve ser diferente. Desse modo, faremos métodos virtuais para este tipo de propriedades com uma implementação comum na classe do objeto gráfico abstratos, e para os objetos herdeiros, sobreporemos esta implementação na classe herdada.
Na seção pública da classe vamos escrever três métodos virtuais que retornam uma descrição do tipo de objeto gráfico e outra do preço e do tempo do primeiro ponto de ancoragem do 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
Nos objetos herdados, substituiremos esses métodos para exibir informações sobre o objeto gráfico específico descrito pela classe herdeira.
Ao construtor de classe paramétrico protegido adicionamos um novo parâmetro formal - um grupo de um objeto gráfico padrão, e, no construtor padrão, escrevemos imediatamente o valor para o grupo igual a -1:
//--- Default constructor CGStdGraphObj(){ this.m_type=OBJECT_DE_TYPE_GSTD_OBJ; m_group=WRONG_VALUE; } protected: //--- Protected parametric constructor CGStdGraphObj(const ENUM_OBJECT_DE_TYPE obj_type, const ENUM_GRAPH_OBJ_BELONG belong, const ENUM_GRAPH_OBJ_GROUP group, const long chart_id, const string name); public: //+--------------------------------------------------------------------+ //|Methods of simplified access and setting graphical object properties| //+--------------------------------------------------------------------+
No final da lista de métodos para acesso simplificado às propriedades da classe escrevemos os métodos que retornam os sinalizadores de visibilidade do objeto no período gráfico especificado. Cada período gráfico tem seu próprio método. E declaramos um método que retorna uma descrição da visibilidade do objeto em todos os períodos gráficos:

No método que exibe no log uma descrição breve do objeto, primeiro imprimimos que se trata de um objeto gráfico padrão:
//+------------------------------------------------------------------+ //| Display a short description of the object in the journal | //+------------------------------------------------------------------+ void CGStdGraphObj::PrintShort(const bool dash=false,const bool symbol=false) { ::Print ( CMessage::Text(MSG_GRAPH_ELEMENT_TYPE_STANDART),": ", " \"",CGBaseObj::Name(),"\": ID ",(string)this.GetProperty(GRAPH_OBJ_PROP_ID), " ",::TimeToString(CGBaseObj::TimeCreate(),TIME_DATE|TIME_MINUTES|TIME_SECONDS) ); } //+------------------------------------------------------------------+
Ao método que retorna uma descrição da propriedade inteira do objeto, adicionamos a exibição da descrição do grupo ao qual o objeto pertence, e vamos substituir a exibição de algumas propriedades chamando os métodos criados para isso:

//+------------------------------------------------------------------+ //| Return description of object's real property | //+------------------------------------------------------------------+ string CGStdGraphObj::GetPropertyDescription(ENUM_GRAPH_OBJ_PROP_DOUBLE property) { int dg=(this.m_digits>0 ? this.m_digits : 1); return ( property==GRAPH_OBJ_PROP_PRICE ?

Ao método, que retorna uma descrição indicando que o objeto possui uma propriedade de string, adicionamos umas aspas que delimitarão as propriedades de string exibidas, e para a descrição de dica de balão exibimos uma mensagem de que é gerada automaticamente pelo terminal caso não seja especificada e não seja o caractere de controle "\n" que a desativa:
//+------------------------------------------------------------------+ //| Return description of object's string property | //+------------------------------------------------------------------+ string CGStdGraphObj::GetPropertyDescription(ENUM_GRAPH_OBJ_PROP_STRING property) { return ( property==GRAPH_OBJ_PROP_NAME ?

Método que retorna uma descrição indicando a visibilidade do objeto no período gráfico:
//+------------------------------------------------------------------+ //| 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; } //+------------------------------------------------------------------+
Aqui, da propriedade do objeto obtemos sinalizadores de bits que indicam a visibilidade do objeto no período gráfico.
Se nenhum dos sinalizadores estiver definido, retornamos uma mensagem de que o objeto é invisível em todos os período gráficos.
Por outra parte, se todos os sinalizadores de todos os períodos gráficos estiverem definidos, retornamos uma mensagem de que o objeto é visível em todos eles.
Se apenas parte dos sinalizadores for definida, no ciclo de 1 a 21 obtemos o período gráfico por índice usando a função de serviço TimeframeByEnumIndex(), que escrevemos há muito tempo e que é armazenada no arquivo de funções de serviço.
Se o objeto estiver invisível no período gráfico recebido, vamos para a próxima iteração para obter o próximo período.
Se o objeto for visível, adicionamos sua descrição breve ao valor da variável res com vírgula e espaço no final.
Depois do ciclo substituímos no final da string resultante o caractere de vírgula adicionado na última iteração do loop por um espaço e removemos todos os espaços e caracteres de controle à direita da string. Retornamos a string resultante desde o método.
Todas as modificações de classe estão concluídas, vamos começar a criar classes herdeiras da classe do objeto gráfico abstrato.
Classes herdeiras do objeto gráfico abstrato
Hoje vamos criar classes de vários grupos de objetos gráficos: "Linhas", "Canais", "Gann", "Fibonacci" e "Elliott".
Na pasta \MQL5\Include\DoEasy\Objects\Graph\Standart\ criamos o novo arquivo GStdHLineObj.mqh da classe de linha horizontal StdHLineObj.
A classe deve ser herdada de um objeto gráfico abstrato, e o arquivo da classe pai deve estar integrado na classe gerada:
//+------------------------------------------------------------------+ //| 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 { }
Na seção pública da classe, adicionamos um construtor, declaramos três métodos que retornam sinalizadores de propriedades suportadas pelo objeto e métodos para exibir descrições do objeto e suas propriedades:
//+------------------------------------------------------------------+ //| "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); } }; //+------------------------------------------------------------------+
O nomes dos métodos já deveria deixar esclarecido para que são usados, e já vimos métodos semelhantes muitas vezes em outras classes.
Na lista de inicialização do construtor da classe, ao construtor paramétrico privado da classe pai passamos o tipo de objeto linha horizontal, a pertença como não pertencendo ao programa, o grupo de objetos linhas e os valores do identificador do gráfico e o nome do objeto passado ao construtor da classe:
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) {}
O método virtual TypeDescription() devolve uma descrição do tipo de objeto gráfico, retornado pela função de serviço StdGraphObjectTypeDescription() que escrevemos anteriormente e à qual passamos o tipo de objeto linha horizontal:
virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); }
O método virtual TimeDescription(), que retorna a descrição de tempo, exibe a hora registrada nas propriedades da linha horizontal. Mas como a linha horizontal não tem referência de tempo, nesta propriedade é inserida a coordenada do cursor do mouse ao clicar no gráfico durante o posicionamento do objeto . Uma mensagem adicional sobre isso é exibida na descrição de tempo apresentada no log:
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 retornam os sinalizadores que indicam se o objeto suporta inteiras, reais e de 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; } //+------------------------------------------------------------------+
A cada método é passada uma propriedade e, depois, se a propriedade estiver na lista de propriedades suportadas, retornamos true; caso contrário, false.
Para cada classe, as listas de propriedades suportadas serão diferentes. Afinal, cada um dos objetos gráficos tem seu próprio conjunto de propriedades. Da mesma forma, os construtores de classes também serão únicos para cada um dos objetos herdeiros do objeto gráfico abstrato.
Método que retorna o nome curto do objeto e exibe no log uma breve descrição do objeto:
//+------------------------------------------------------------------+ //| 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) ); } //+------------------------------------------------------------------+
Esses métodos (1) retornam uma string que descreve o tipo do objeto gráfico e (2) registram o tipo, o nome, o identificador atribuído ao objeto quando criado e a hora de criação do objeto.
Todas as outras classes que descrevem diferentes tipos de objetos gráficos pertencentes a diferentes grupos deverão ser consideradas em sua totalidade por conta própria.

Estes são todos os objetos de classes herdeiras do objeto gráfico abstrato previstos para hoje. Como podemos ver, são idênticos, mas diferem nos tipos de propriedades suportadas. Desse modo, todos estes objetos terão apenas as propriedades inerentes a cada um deles. Aqui a vantagem não está apenas na exibição desses dados no log, mas precisamente no fato de que a busca e classificação de objetos na biblioteca leva em conta os sinalizadores que indicam que o objeto tem determinada propriedade. Por isso, ao classificar todos os objetos gráficos na coleção, por exemplo, por ângulo, os objetos que não possuem nenhum ângulo não poderão entrar na lista final, já que não suportam tal propriedade.
Vamos deixar todas as classes acima para realizarmos uma análise independente.
Agora precisamos modificar a classe para gerenciar objetos gráficos localizados no arquivo da classe-coleção de objetos gráficos no caminho \MQL5\Include\DoEasy\Collections\GraphElementsCollection.mqh.
Precisamos ter certeza de que, dependendo do objeto gráfico adicionado ao gráfico, uma nova instância da classe de objeto gráfico padrão seja criada a partir daquelas que criamos hoje. Vamos fazer as modificações necessárias no arquivo.
Hoje incluiremos os arquivos - de todas as classes criadas hoje - no arquivo da classe-coleção de objetos gráficos (em vez do arquivo GStdGraphObj.mqh incluído anteriormente) e declaramos um método público para criar um novo objeto que descreve o objeto gráfico adicionado ao gráfico:

No método que verifica a mudança no número de objetos no gráfico, da classe de gerenciamento de objetos gráficos, vamos fazer alguns pequenos ajustes no bloco de código para criar um novo objeto que descreve o objeto gráfico adicionado ao 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 ?

Anteriormente, aqui criávamos um novo objeto gráfico abstrato. Agora criamos um objeto do respectivo tipo, utilizando as classes herdeiras criadas hoje. Após criar com sucesso o objeto, adicionar ao mesmo a propriedade de pertença (não pertencente ao programa) e, em vez de exibir uma breve descrição do objeto criado, imprimimos no log uma descrição completa de todas as suas propriedades.
Para selecionar o objeto que desejamos criar, usamos o método que gera um novo objeto gráfico padrão:
//+------------------------------------------------------------------+ //| 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; } } //+------------------------------------------------------------------+
Aqui simplesmente ao método são passados o tipo de objeto que precisa ser criado, o identificador do gráfico ao qual o objeto gráfico foi adicionado e o nome do novo objeto gráfico. Em seguida, dependendo do tipo de objeto gráfico passado ao método, criamos por meio do operador new um novo objeto da devida classe herdeira do objeto gráfico abstrato e retornamos imediatamente o resultado da criação deste novo objeto.
O método retorna o ponteiro para o objeto recém-criado ou NULL em caso de falha. Como podemos ver, nem todos os objetos são criados ainda. Faremos o resto no próximo artigo, junto com as melhorias que definitivamente integraremos nas classes criadas hoje. Na verdade, precisaremos dar acesso a todas as propriedades de todos os pontos de ancoragem do objeto, e não ao primeiro como foi feito nesta fase.
Estamos prontos para o teste.
Teste
Para o teste, vamos pegar o Expert Advisor do artigo anterior e o salvamos na nova pasta \MQL5\Experts\TestDoEasy\Part84\ com o novo nome TestDoEasyPart84.mq5.
Não precisamos fazer nenhuma mudança no EA nesta fase. Mas por uma questão de ordem, nós o salvamos na pasta de artigos correspondente do terminal.
Vamos compilar o Expert Advisor e executá-lo no terminal. Também vamos adicionar alguns objetos gráficos ao gráfico.
O log exibirá descrições completas de todas as propriedades dos objetos adicionados ao gráfico:
O que vem agora?
No próximo artigo, continuaremos a desenvolver as classes herdeiras dos objetos gráficos abstratos e a classe-coleção de objetos gráficos da biblioteca.
Todos os arquivos da versão atual da biblioteca e o arquivo do EA de teste para MQL5 estão anexados abaixo. Você pode baixá-los e testar tudo por conta própria.
Se você tiver dúvidas, comentários e sugestões, pode expressá-los nos comentários ao artigo.

Como se tornar um bom programador (Parte 4): agilizando a velocidade de programação
Suponho que todo desenvolvedor quer escrever código mais rapidamente. Porém, a habilidade de escrever código de forma rápida e produtiva não é uma característica inata que apenas uns poucos trazem consigo. Trata-se de uma habilidade que qualquer programador pode desenvolver e que será o tópico deste artigo.
Analisando o spread para preços de Bid e Ask no MetaTrader 5
Neste artigo falo de uma ferramenta capaz de ver os spreads, isto é, as diferenças entre os valores Bid e Ask da sua corretora. Os dados de ticks presentes no MetaTrader 5 possibilitam analisar quais valores históricos de spreads existiam de fato entre os valores Bid e Ask. Contudo, não há razão para procurar o valor atual do spread, pois ele pode ser obtido por meio da visualização das linhas Bid e Ask.
