I am an expert with a comprehensive understanding of web development, specifically in the context of JavaScript and jQuery. I possess a deep knowledge of front-end scripting, including the manipulation of the Document Object Model (DOM) and asynchronous communication with servers using AJAX. My expertise extends to handling events, managing cookies, and employing various techniques for optimizing and enhancing user interfaces.

Now, let's delve into the provided code and explain the concepts used:

jQuery: The code extensively uses jQuery, a fast and concise JavaScript library, to simplify HTML document manipulation, event handling, and AJAX requests.
Asynchronous Requests (AJAX): The $.ajax() function is employed to make asynchronous HTTP requests to the server. It's utilized to fetch data without requiring a page reload.
DOM Manipulation: The code dynamically manipulates the DOM (Document Object Model) by creating, modifying, and appending HTML elements. For instance, it builds tables, rows, and buttons dynamically based on the received data.
Date Formatting with Moment.js: The moment library is used to format dates. The moment() function is applied to format dates in the "ddd" and "DD.MM" formats.
Conditional Rendering: The code includes conditional statements to determine whether to render certain elements based on the values of properties like curs, diff, and IsEng.
Number Formatting: The number_format function is implemented for formatting numerical values. It includes options for decimal precision, decimal point, and separator.
Cookie Handling: The $.cookie() function is utilized for handling cookies. It stores and retrieves information about the selected tab, enabling the persistence of user preferences across page reloads.
Event Handling: Event handling is prominent in the code. For instance, the .click() method is used to define actions when certain elements, such as tabs or buttons, are clicked.
Error Handling: The code includes error handling for AJAX requests. It displays error messages when there are issues with fetching data from the server.
Language Localization: The code checks the language of the page (English or Russian) and adjusts the content accordingly. This is evident in phrases like "Load more" and "Загрузить еще."
CSS Styling: While not explicitly shown in the provided snippet, the code likely relies on CSS styles to control the visual presentation of elements, such as background images and text formatting.

In summary, the code showcases a sophisticated implementation of web development techniques using jQuery, AJAX, DOM manipulation, and various utility libraries to create a dynamic and responsive user interface for handling financial data.
