   For better representation, search results now contain not only texts but also avatars of articles, books and applications. Use the top panel to view the search results by MetaTrader Appstore Products, Code Base, Signals, MQL5.community Forum and Documentation. If a category has no results, it is highlighted in gray.
   
   
2. Another new product category has been added to MetaTrader AppStore following trading and financial magazines - Books. Now, you can purchase the works of well-known traders and analysts along with trading robots and indicators. The range of books is increasing daily.
   

   
   
   

   
   Just like MetaTrader 4 applications, books can be purchased at MQL5.community Market as well as directly via MetaTrader 4 terminal. All books are accompanied by descriptions and screenshots:
   

   
   
   

   
   Before making a purchase, you can download a preview - the first few pages of a book. The exact number of available pages is defined by a seller.
   
   To buy a book, you should have an MQL5.com account and the necessary amount of funds on it. The account data should be specified at the Community tab of the terminal settings:
   

   
   
   

   
   Click Buy on the book's page to purchase it. Purchase confirmation dialog appears:
   

   
   
   

   
   To continue, agree to the rules of using the Market service and enter your MQL5.community password. After that, the specified amount of funds will be withdrawn from your account and the book will be downloaded. Buy button will be replaced by Open one.
   
   Book files are downloaded to My Documents\MQL5 Market\Books\. The download may be performed in two formats:
   
   
   • MQB - this protected format is used for paid books. When purchasing and downloading a book file, it is encoded so that it can be opened only on the PC it has been downloaded to. Generation of an encoded copy is called activation. Each book can be activated at least 5 times on different hardware. Book sellers can increase the number of activations at their sole discretion.
   • PDF - this format is used for free books and previews. After downloading, such file can be moved and viewed on other devices.
     
   
   The special component called MetaViewer has been added to MetaTrader 4 terminal allowing users to view book files. MetaViewer is a convenient application for viewing books and magazines in MQB and PDF formats. Keyboard arrows are used to turn over the pages: left and right arrows - for page-by-page navigation, while up and down arrows - for scrolling.
