Introdução

No artigo Gerenciando o terminal MetaTrader via DLL a autora descreve como administrar a plataforma MetaTrader 4 controlando a interface gráfica do usuário (GUI) por meio de uma biblioteca dinâmica personalizada (dll). Neste artigo vamos utilizar a funcionalidade do AutoIt. Com ela vamos criar uma classe que permite automatizar tarefas que não podem ser feitas em MQL5 puro.

Estas tarefas incluem:

Adicionar e remover scripts ou EAs dos gráficos.
Ler os EAs do terminal e das guias do log na janela de ferramentas.
Processar automaticamente avisos (leitura de mensagens de aviso e fechamento automático de janelas de aviso).
Finalmente, implementaremos a mesma funcionalidade que foi mostrada no artigo do MetaTrader 4 - configuração de MetaQuotes ID no terminal.

AutoIt

O AutoIt é uma linguagem em forma de script para automatizar a interface gráfica do usuário do Microsoft Windows. Entre outras coisas, ele permite controlar janelas, usar componentes da interface do usuário e simular o mouse e o teclado. Parte do AutoIt é AutoItX. Trata-se de uma dll que implementa algumas das funções da linguagem de script do AutoIt. Ao interagir com esta dll, podemos adicionar recursos de scripting GUI à MQL5.

Instalação

O AutoIt está disponível gratuitamente neste link. Funciona em todas as versões x86 do Microsoft Windows, incluindo a 10. Este é um aplicativo de 32 bits que vem com vários componentes de 64 bits, incluindo uma versão de 64 bits do AutoItX. Se você deseja saber mais sobre o programa, o arquivo de ajuda que faz parte da instalação do aplicativo deve ser lido. Antes de prosseguirmos, precisamos estar cientes das limitações.

Limitações

O AutoIt só pode funcionar de forma confiável com componentes padrão do Microsoft Windows, com base na API do Win32. Caso use programas com componentes personalizados, o AutoIt não funcionará. Isso é verdade sobretudo para software criado usando estruturas de plataforma cruzada. Podemos verificar se a interface do usuário de um programa é compatível com o AutoIt usando a ferramenta AutoIt Window Info Tool. Outra limitação a ser observada é provocada pelo facto do AutoItX implementar apenas parte do que a linguagem de script AutoIt é capaz. É possível que um componente possa ser manipulado pelo AutoIt, mas a mesma funcionalidade pode não estar disponível via AutoItX.

AutoIt Window Info Tool

O AutoIt vem com uma ferramenta chamada AutoIt Window Info Tool que é usada para obter informações sobre as janelas do aplicativo.

Ao arrastar a ferramenta Finder sobre qualquer parte de um aplicativo de destino, podemos obter as propriedades de um componente específico. Esses componentes são chamados de controles. Um controle pode ser um botão, um menu suspenso ou uma guia. Estes são apenas alguns exemplos, existem muitos tipos de controles usados para construir aplicativos. Cada controle está associado a uma janela. Um aplicativo pode ser composto por várias janelas. Normalmente, há uma janela principal, na qual outras janelas filhas são anexadas ou ancoradas. Se as janelas filhas estiverem anexadas ou encaixadas na janela principal do aplicativo, todos os controles incluídos nessas janelas filhas se tornarão parte da janela principal do aplicativo. Ao usar o AutoIt para localizar com precisão um controle, a janela à qual o controle está associado é importante, seja uma janela filha ou a janela principal do aplicativo.

Observando o gráfico abaixo, podemos ver a ferramenta de busca sendo arrastada sobre diferentes regiões de um aplicativo Metatrader 5. Note as configurações do Window Info Tool quando o menu Otions estiver selecionado. As opções Freeze, Always On Top e Use Spy++ Control Detection Logic estão marcadas.

A guia Window mostrará as propriedades da janela em que apontada o cursor-mira, aqui são listados o título e a classe da janela. Essas propriedades podem ser usadas para identificá-la exclusivamente. Na guia Control, podemos ver as propriedades do controle, de interesse aqui é a propriedade ClassnameNN. (Observe que o nome da classe no AutoIt se refere ao tipo de um controle). Esta propriedade combina o tipo de controle com um identificador de instância na forma de um número. Conhecer o tipo de um controle é essencial, pois isso determinará quais chamadas de função AutoIt funcionarão nele.

Integração do AutoItX

Para garantir uma integração bem-sucedida com o MetaTrader 5, precisamos ter certeza de que o terminal pode encontrar a dll necessária durante o tempo de execução. Para conseguir isso, precisamos simplesmente copiar a dll necessária para a pasta Libraries da nossa instalação do MetaTrader 5. O diretório de instalação padrão do AutoIt3 estará na pasta Arquivos de programas (x86). A pasta AutoItX dentro dela contém todos os componentes relacionados ao AutoItX, incluindo o cabeçalho AutoItX3_Dll que lista todos os protótipos de função expostos na dll. É importante obter a dll apropriada para sua compilação do MetaTrader 5 (64 ou 32 bits).

Qualquer programa MetaTrader 5 que use a biblioteca AutoItX terá primeiro que importar suas funções. Por conveniência, criaremos um arquivo de inclusão autoIt.mqh cujo único objetivo será importar todos os protótipos de funções fornecidos pela biblioteca.

O AutoIt é estritamente uma ferramenta do sistema operacional Microsoft Windows que aproveita a API do Windows. Esta é a razão pela qual a biblioteca AuotItX faz uso extensivo de tipos de dados específicos da API Win32. Para garantir a compatibilidade com MQL5, podemos implementar esses tipos de dados em MQL5, mas isso não é necessário. Em vez disso, podemos usar o arquivo windef.mqh que faz parte dos esforços da MetaQuotes para integrar a API Win32 na linguagem MQL5. O arquivo contém a maioria das definições de tipo de dados usadas na API do Windows.
Incluiremos windef.mqh em nosso arquivo autoit.mqh que conterá todos os protótipos de função importados da dll. O arquivo de código autoit.mqh agora tem a seguinte aparência:

Informações preliminares de uso
O uso da biblioteca em MQL5 requer a inicialização da dll chamando primeiro a função AU3_Init. Isso deve ser feito antes que qualquer uma das outras funções importadas seja chamada. As assinaturas de função são análogas àquelas usadas na linguagem de script AutoIt, o que significa que elas têm parâmetros de função e tipos de retorno semelhantes. É necessário estar familiarizado com a linguagem de script do AutoIt, para entender como as funções trabalham, novamente todas essas informações estão disponíveis no arquivo de ajuda que faz parte da instalação do aplicativo.

As funções que retornam um valor, retornam valores numéricos positivos, geralmente 1 em caso de sucesso e 0 em caso de falha. A saída de funções void para uma referência de string ou de estrutura. Para esses tipos de funções, você pode chamar a função AU3_error() para confirmar se ocorreu um erro. A função também simplesmente produzirá uma string com "0" ou uma estrutura vazia quando a função falhar. As funções que geram referências de string também especificam um parâmetro de tamanho de buffer. Isso significa que o comprimento do buffer para a string passada por referência deve ser definido explicitamente antes de chamar a função. Caso contrário, se o comprimento do buffer de string não for definido, um erro será confirmado. Se o tamanho alocado do buffer for insuficiente, a função exibirá os caracteres que cabem no espaço especificado, deixando de fora o resto, produzindo uma string truncada. Não há como saber a quantidade de espaço necessária para a saída, portanto, é necessário estar ciente dessa peculiaridade. Para definir o tamanho do buffer para uma string, podemos usar a função MQL5 integrada StringInit. Existem algumas funções que possuem o sufixo ...ByHandle, por exemplo AU3_WinCloseByHandle(). Esta função faz a mesma coisa que AU3_WinClose(), a diferença é que a função com sufixo ByHandle funciona identificando um controle ou janela pelo seu descritor. O uso dessas funções é preferível, pois ajuda na depuração, pois será mais fácil encontrar erros relacionados à identificação da janela ou controle correto.

Exemplo inicial
O exemplo abaixo demonstra o uso das funções AutoItX em MQL5. No script abaixo, usaremos a função AU3_WinGetHandle para obter o descritor da janela principal do terminal. O terminal pode ser identificado exclusivamente pelo número da conta ativa exibido na barra de título da janela.

      Print("Failed to set string bufferlength with error - "+string(GetLastError()));

   HWND window_handle=AU3_WinGetHandle(IntegerToString(AccountInfoInteger(ACCOUNT_LOGIN)),"");// get the terminal's handle

   if(!window_handle)
      Print("Could not find main app window. Error is "+string(AU3_error()));

   AU3_WinGetClassListByHandle(window_handle,sbuffer,1000);// get classnames of all user interface componets of the terminal

   Print(sbuffer);

  }
//+------------------------------------------------------------------+

Assim que tivermos um descritor para a janela principal, podemos obter mais informações sobre os componentes da GUI com os quais podemos interagir chamando a função AU3_WinGetClassListByHandle. Ele retornará uma lista de strings que são os nomes de classe de todos os componentes da interface do usuário associados ao descritor de janela fornecido.

O resultado do script é mostrado abaixo.

Resultado de TerminalUIComponents

Antes de passar para exemplos mais ilustrativos, vamos criar uma classe que envolva a maioria das funções AutoIt importadas.

Classe CAutoit

CAutoit será a classe base para outras classes que usam a biblioteca AutoItX. Ela terá uma única propriedade estática indicando se a função de inicialização da biblioteca AU3_Init() foi chamada ou não.

A única outra propriedade, m_buffer_size, determina o comprimento do buffer de string usado nas chamadas de método.

Classe CTerminalController

Agora vamos criar a classe CTerminalController no arquivo terminalcontroller.mqh.
Primeiro, incluímos o arquivo autoitbase.mqh que contém a classe CAutoIt. Usamos diretivas de pré-processador para definir constantes de string que identificam os componentes da interface do usuário com os quais a classe trabalhará.
Antes de especificar a classe, declaramos uma enumeração personalizada que classifica os programas MetaTrader 5 como um script ou um Expert Advisor.

   long              m_chartid;                  //chart id
   long              m_accountNum;               //account number
   string            m_buffer;                   //string buffer

m_chartid refere-se ao ID do gráfico determinado pela chamada da função MQL5 chartID().
m_accountNum é o número da conta ativa exibido na barra de título do aplicativo do terminal. Este valor será usado para distinguir uma janela de terminal ativa de outra.
Mensagens de erro detalhadas serão gravadas na linha m_buffer caso algo dê errado.

public:
   //default constructor
                     CTerminalController(void): m_terminal(0),
                     m_journaltab(0),
                     m_expertstab(0),
                     m_navigator(0),

      StringInit(m_buffer,1000);
     }
   //destructor

     }

CTerminalController terá um construtor. O construtor padrão inicializa m_accountNum com a conta atualmente ativa retornada pela chamada de função AccountInfoInteger.

GetErrorDetails() é usado para obter mensagens de erro. A função retorna o conteúdo do membro privado m_buffer. Por outro lado, SetErrorDetails() é um método privado que é usado internamente para definir o conteúdo do elemento string m_buffer.

//+------------------------------------------------------------------+

O método Initialize() deve ser chamado pelo menos uma vez durante a inicialização do programa antes de qualquer outro método. O método tem um único parâmetro padrão, accountNumber. Se o argumento for diferente de zero, ele redefine o valor da propriedade da classe m_accountNum, que por sua vez redefine todas as outras propriedades da classe, iniciando uma busca pela janela do terminal principal identificada pela propriedade m_accountNum. Uma vez que a janela principal é encontrada, todos os outros descritores de controle são recuperadas e usadas para definir as propriedades restantes da classe.

ChartExpertAdd() é usado para anexar Expert Advisors ou scripts a gráficos. Parâmetros da função:

p_type - tipo de programa: EA ou script,
ea_name - nome do script ou EA conforme exibido na janela do navegador. As extensões de arquivo não são levadas em consideração.
ea_relative_path - caminho relativo para a subpasta que contém o programa especificado pelo parâmetro ea_name na pasta Scripts ou Experts. Por exemplo, o Expert Advisor Controls mostrado na figura abaixo está contido em uma pasta chamada Controls, em uma subpasta chamada Examples, que por sua vez está localizada na pasta Experts, ou seja, seu caminho é isso aí: Examples\Controls. Se o programa não estiver localizado em nenhuma subpasta da pasta Scripts ou da pasta Experts, esse argumento deve ser NULL ou "".

ea_set_file é o nome do arquivo .set. A extensão do arquivo .set deve ser especificada para este argumento.
Os argumentos chart_symbol e chart tf definem as propriedades do gráfico ao qual o programa será adicionado.

Primeiro, o método SwitchToNewChart() é chamado. Este método procura o gráfico solicitado entre as janelas de gráfico abertas no momento. Se encontrado, o foco é definido para ele, caso contrário, a função ChartOpen() é usada para abrir um novo gráfico. O método também é responsável por definir a propriedade m_chartid da classe.
A propriedade m_chartid é então usada para verificar se o programa já foi adicionado ao gráfico. Se o programa existir, o método retornará true.

Se o programa não for encontrado, ele se prepara para uma busca na área do Navegador. Se a guia Geral do painel Navegador não estiver visível, ela está habilitada.
Uma vez habilitada, o método Findprogram() é chamado para procurar o programa MetaTrader 5 no controle systreeview32. O método obtém suporte para o método recursivo FindBranch().

FindBranch() percorre o controle e também cria um ID de link de linha, que é o caminho para o local dos programas no controle systreeview32. O ID do link do programa é necessário para que o AutoIt possa ser usado para selecioná-lo e adicioná-lo ao gráfico.

Neste estágio, se o programa for um Expert Advisor e já houver outro no gráfico, uma caixa de diálogo aparecerá confirmando a substituição do Expert Advisor atualmente em execução.

Se o programa em execução tiver dados de entrada, o loop do... while percorre as guias, define o arquivo .set e habilita a negociação automática e as exportações de dll, se necessário.

Por fim, o método retorna o resultado da nova verificação do gráfico para que o programa confirme se ele foi adicionado ao gráfico.

ChartExpertRemove() remove um script ou um Expert Advisor do gráfico. Isso é feito chamando a caixa de diálogo "Experts" no menu principal do aplicativo.

A função ChartExpertRemoveAll() remove todos os Expert Advisors e scripts, exceto o programa que realiza a remoção.

As funções GetLastExpertsLogEntryByText() e GetLastJournalEntryByText() retornam a última entrada que corresponde ao parâmetro text_to_search_for. As funções começam a pesquisar da entrada de log mais recente para trás. O parâmetro max_items_to_search_in define o número máximo de entradas de diário com as quais trabalhar. Por exemplo, se definido como 10, a função percorrerá as últimas 10 entradas de log procurando por correspondências. Se este parâmetro for definido como 0 ou um número negativo, a função percorre todas as entradas de log.

Conclusão

O artigo descreveu brevemente como trabalhar com o AutoIt. Mostrei como você pode usar a biblioteca AutoItX após integrá-la à linguagem MQL5, e também documentei a criação de uma classe que usa a dll AutoIt. A única limitação encontrada ao usar a biblioteca é que a execução de dois ou mais programas MetaTrader 5 usando AutoItX ao mesmo tempo causa erros de violação de acesso. Portanto, é recomendável executar instâncias separadas de programas MetaTrader 5 que façam referência a qualquer código AutoItX.

Pasta	Sumário	Descrição
MetaTrader 5zip\MQL5\include	autoIt.mqh, autoItbase.mqh,terminalcontroller.mqh	autoIt.mqh contém operadores de importação das funções AutoItX, autoItbase.mqh contém a classe CAutoIt, e terminalcontroller.mqh contém a classe CTerminalController
MetaTrader 5zip\MQL5\Experts	TerminalController.mq5,HandleAlerts.mq5	O EA TerminalController demonstra como remover e adicionar EAs/scripts ao gráfico automaticamente. O EA HandleAlerts mostra como automatizar o processamento de balões de aviso
MetaTrader 5zip\MQL5\Scripts	TerminalUIComponents.mq5,Send_Push.mq5	TerminalUICommpents demonstra o uso de AutoItX por meio da chamada direta de funções importadas, o script Send_Push adiciona ID MetaQuotes novas ao terminal antes do envio de notificações

Matrizes e vetores em MQL5

Os tipos de dados especiais matrix e vector permitem escrever um código que se aproxima da notação matemática. Isto poupa o trabalho de criar laços aninhados e de lembrar de indexar corretamente as matrizes que estão envolvidas no cálculo. Isto aumenta a confiabilidade e a velocidade de desenvolvimento de programas complexos.

Melhorando o reconhecimento de padrões de velas por meio de velas Doji
