В статье завершим работу над классами объектов-чартов и их коллекцией. Сделаем автоматическое отслеживание изменения свойств чартов и их окон, а также сохранение новых параметров в свойства объекта. Такая доработка позволит в будущем сделать событийный функционал для всей коллекции чартов.

В статье создадим функционал отслеживания некоторых событий объектов-чартов — добавление и удаление графиков символов, добавление и удаление подокон на график, а также добавление/удаление/изменение индикаторов в окнах чартов.

В статье расширим функционал объектов-чартов, организуем навигацию по графикам, создание скриншотов, сохранение и применение шаблонов к графикам. Также сделаем автоматическое обновление коллекции объектов-чартов, их окон и индикаторов в них.

С этой статьи начнём разработку класса-коллекции объектов-чартов, который будет хранить в себе список-коллекцию объектов-чартов с их подокнами и индикаторами в них, и даст возможность работы с любыми выбранными чартами и их подокнами, или сразу со списком из нескольких чартов одновременно.

In this article, I will continue the development of the chart object class. I will add the list of chart window objects featuring the lists of available indicators.

In this article, I will create the chart object class (of a single trading instrument chart) and improve the collection class of MQL5 signal objects so that each signal object stored in the collection updates all its parameters when updating the list.

In this article, I will create the signal collection class of the MQL5.com Signals service with the functions for managing signals. Besides, I will improve the Depth of Market snapshot object class for displaying the total DOM buy and sell volumes.

In this article, I will create the collection class of Depths of Market of all symbols and start developing the functionality for working with the MQL5.com Signals service by creating the signal object class.

In this article, I will create two classes (the class of DOM snapshot object and the class of DOM snapshot series object) and test creation of the DOM data series.

In the article, I will start developing the functionality for working with the Depth of Market. I will also create the class of the Depth of Market abstract order object and its descendants.

In this article, I will implement updating tick data in real time and prepare the symbol object class for working with Depth of Market (DOM itself is to be implemented in the next article).

Since a program may use different symbols in its work, a separate list should be created for each of them. In this article, I will combine such lists into a tick data collection. In fact, this will be a regular list based on the class of dynamic array of pointers to instances of CObject class and its descendants of the Standard library.

In this article, I will create the list for storing tick data of a single symbol and check its creation and retrieval of required data in an EA. Tick data lists that are individual for each used symbol will further constitute a collection of tick data.

From this article on, start creating library functionality to work with price data. Today, create an object class which will store all price data which arrived with yet another tick.

In conclusion of the topic of working with timeseries organise storage, search and sort of data stored in indicator buffers which will allow to further perform the analysis based on values of the indicators to be created on the library basis in programs. The general concept of all collection classes of the library allows to easily find necessary data in the corresponding collection. Respectively, the same will be possible in the class created today.

In the article, develop an object which will contain all data of one buffer for one indicator. Such objects will be necessary for storing serial data of indicator buffers. With their help, it will be possible to sort and compare buffer data of any indicators, as well as other similar data with each other.

The article considers creation of the custom indicator object for the use in EAs. Let’s slightly improve library classes and add methods to get data from indicator objects in EAs.

The article continues developing indicator object classes and their collections. For each indicator object create its description and correct collection class for error-free storage and getting indicator objects from the collection list.

The article considers creation of classes of descendant objects of base abstract indicator. Such objects will provide access to features of creating indicator EAs, collecting and getting data value statistics of various indicators and prices. Also, create indicator object collection from which getting access to properties and data of each indicator created in the program will be possible.

The article considers creation of an abstract indicator which further will be used as the base class to create objects of library’s standard and custom indicators.
