MetaTrader 4 Client Terminal build 825

Release Notes: MetaTrader 4

22 May 2015


  1. The new feature in MetaTrader Market allows providing products for rent for 1, 3, 6 or 12 months. This provides undeniable advantages both for developers and buyers. Sellers can significantly increase user confidence in their products, giving the customer a chance to thoroughly check the product functionality at a low cost. For buyers, the rent is another opportunity to assess a product before buying it. Unlike demo versions, rented products have no limitations except for validity period.

    Any developer in the Market may choose whether or not to provide their products for rent, and what will be the cost of this rent.

    Developers may choose not to offer their products for rent selling only full licenses for unlimited use.

    If rent is enabled for a product, its web page shows possible options: rental period and price. Click "Rent" and select the rental period.

    After expiration, you can either extend the product rental period or purchase an unlimited version of the product.

  2. We are introducing a new mechanism of "direct" purchasing. Purchasing a trading robot or an indicator from the Market is now even easier, and you do not even need an account.

    One-Step Purchase
    A user doesn't need to log in to an account and add money to it. A payment for a product can now be made straight from the platform using one of the available payment systems. To maintain a clear and unified history of purchases from the Market, the required amount will be first transfered to your account, from which a payment for the product will be made.

    You can easily access and review all your payments from your Profile.

  1. The Strategy Tester now allows testing not only Expert Advisors, but also indicators. This can be done in the visual testing mode. The behavior of the indicator is shown on a chart, which is plotted based on a sequences of ticks simulated in the tester.

    This feature is especially useful for the users who want to purchase an indicator from the MetaTrader Market. Before purchasing an indicator, you can download a free trial version and see its backtest performance in the strategy tester.

Virtual Hosting

  1. Multiple improvements and fixes have been implemented in the Virtual Hosting service.

    The major changes apply to operation in Wine on computers running Linux and Mac OS. Now you can work with an allocated virtual server as usual: migrate it, monitor its performance and view logs.

    MetaTrader 4 running under Wine now allows to use Vistual Hosting Service

    The operation of the Log has also changed. If a user requests too many records, then only part of the first logs for the specified period will be downloaded. This prevents performance degradation resulting from large logs. If you want to download further logs, you no longer need to change the request period. Simply select the last line in the log viewer window and press PgDn.

    MetaTrader 4 Logs now can work with huge amount of messages

    int  WebRequest(
       const string      method,           // HTTP method
       const string      url,              // url address
       const string      headers,          // Headers
